the g_spawn functions.&lt;/doc&gt;

           line=&quot;70&quot;&gt;A GQuark is a non-zero integer which uniquely identifies a
particular string.

A GQuark value of zero is associated to `NULL`.

Given either the string or the `GQuark` identifier it is possible to
retrieve the other.

Quarks are used for both
[datasets and keyed data lists](datalist-and-dataset.html).

To create a new quark from a string, use [func@GLib.quark_from_string]
or [func@GLib.quark_from_static_string].

To find the string corresponding to a given `GQuark`, use
[func@GLib.quark_to_string].

To find the `GQuark` corresponding to a given string, use
[func@GLib.quark_try_string].

Another use for the string pool maintained for the quark functions
is string interning, using [func@GLib.intern_string] or
[func@GLib.intern_static_string]. An interned string is a canonical
representation for a string. One important advantage of interned
strings is that they can be compared for equality by a simple
pointer comparison, rather than using `strcmp()`.&lt;/doc&gt;

`g_ref_string_*()` methods called on it. `g_ref_string_*()` methods cannot be
called on `char*` arrays not allocated using g_ref_string_new().

If using #GRefString with autocleanups, g_autoptr() must be used rather than
g_autofree(), so that the reference counting metadata is also freed.&lt;/doc&gt;

since it is not equivalent to `time_t` on 64-bit platforms
with a 64-bit `time_t`.

Unrelated to #GTimer.

Note that #GTime is defined to always be a 32-bit integer,
unlike `time_t` which may be 64-bit on some systems. Therefore,
#GTime will overflow in the year 2038, and you cannot use the
address of a #GTime variable as argument to the UNIX time()
function.

Instead, do the following:

|[&amp;lt;!-- language=&quot;C&quot; --&amp;gt;
time_t ttime;
GTime gtime;

time (&amp;amp;ttime);
gtime = (GTime)ttime;

a multiple of this alignment. For example, most platforms require int variables
to be aligned at a 4-byte boundary, so `G_ALIGNOF (int)` is 4 on most platforms.

Note this is not necessarily the same as the value returned by GCC’s
`__alignof__` operator, which returns the preferred alignment for a type.
The preferred alignment may be a stricter alignment than the minimal
alignment.&lt;/doc&gt;

get pointers to items as arguments. If the element is found, %TRUE
is returned and the element’s index is returned in @out_match_index
(if non-%NULL). Otherwise, %FALSE is returned and @out_match_index
is undefined. If @target exists multiple times in @array, the index
of the first instance is returned. This search is using a binary
search, so the @array must absolutely be sorted to return a correct
result (if not, the function may produce false-negative).

The @clear_func will be called when an element in the array
data segment is removed and when the array is freed and data
segment is deallocated as well. @clear_func will be passed a
pointer to the element to clear, rather than the element itself.

Note that in contrast with other uses of #GDestroyNotify
functions, @clear_func is expected to clear the contents of
the array element it is given, but not free the element itself.

user data argument.

This is guaranteed to be a stable sort since version 2.32.

There used to be a comment here about making the sort stable by
using the addresses of the elements in the comparison function.
This did not actually work, so any such code should be removed.&lt;/doc&gt;

The sort function @func is passed two elements of the @queue.
It should return 0 if they are equal, a negative value if the
first element should be higher in the @queue or a positive value
if the first element should be lower in the @queue than the second
element.

This function requires that the @queue is sorted before pushing on

The sort function @func is passed two elements of the @queue.
It should return 0 if they are equal, a negative value if the
first element should be higher in the @queue or a positive value
if the first element should be lower in the @queue than the second
element.

This function will lock @queue before it sorts the queue and unlock
it when it is finished.

If you were sorting a list of priority numbers to make sure the
lowest priority would be at the top of the queue, you could use:
|[&amp;lt;!-- language=&quot;C&quot; --&amp;gt;
 gint32 id1;
 gint32 id2;

 id1 = GPOINTER_TO_INT (element1);
 id2 = GPOINTER_TO_INT (element2);

           line=&quot;75&quot;&gt;`GBookmarkFile` lets you parse, edit or create files containing bookmarks.

Bookmarks refer to a URI, along with some meta-data about the resource
pointed by the URI like its MIME type, the application that is registering
the bookmark and the icon that should be used to represent the bookmark.
The data is stored using the
[Desktop Bookmark Specification](http://www.gnome.org/~ebassi/bookmark-spec).

The syntax of the bookmark files is described in detail inside the
Desktop Bookmark Specification, here is a quick summary: bookmark
files use a sub-class of the XML Bookmark Exchange Language
specification, consisting of valid UTF-8 encoded XML, under the
`&amp;lt;xbel&amp;gt;` root element; each bookmark is stored inside a
`&amp;lt;bookmark&amp;gt;` element, using its URI: no relative paths can
be used inside a bookmark file. The bookmark may have a user defined
title and description, to be used instead of the URI. Under the
`&amp;lt;metadata&amp;gt;` element, with its owner attribute set to
`http://freedesktop.org`, is stored the meta-data about a resource
pointed by its URI. The meta-data consists of the resource&#039;s MIME
type; the applications that have registered a bookmark; the groups
to which a bookmark belongs to; a visibility flag, used to set the
bookmark as &quot;private&quot; to the applications and groups that has it
registered; the URI and MIME type of an icon, to be used when
displaying the bookmark inside a GUI.

Here is an example of a bookmark file:
[bookmarks.xbel](https://gitlab.gnome.org/GNOME/glib/-/blob/HEAD/glib/tests/bookmarks.xbel)

A bookmark file might contain more than one bookmark; each bookmark
is accessed through its URI.

The important caveat of bookmark files is that when you add a new
bookmark you must also add the application that is registering it, using
[method@GLib.BookmarkFile.add_application] or [method@GLib.BookmarkFile.set_application_info].
If a bookmark has no applications then it won&#039;t be dumped when creating
the on disk representation, using [method@GLib.BookmarkFile.to_data] or
[method@GLib.BookmarkFile.to_file].&lt;/doc&gt;

             line=&quot;3264&quot;&gt;Adds the application with @name and @exec to the list of
applications that have registered a bookmark for @uri into
@bookmark.

Every bookmark inside a #GBookmarkFile must have at least an
application registered.  Each application must provide a name, a
command line useful for launching the bookmark, the number of times
the bookmark has been registered by the application and the last
time the application registered this bookmark.

If @name is %NULL, the name of the application will be the
same returned by g_get_application_name(); if @exec is %NULL, the
command line will be a composition of the program name as
returned by g_get_prgname() and the &quot;\%u&quot; modifier, which will be
expanded to the bookmark&#039;s URI.

This function will automatically take care of updating the
registrations count and timestamping in case an application
with the same @name had already registered a bookmark for
@uri inside @bookmark.

If no bookmark for @uri is found, one is created.&lt;/doc&gt;

applications that have registered a bookmark for @uri inside
@bookmark.

You should rarely use this function; use g_bookmark_file_add_application()
and g_bookmark_file_remove_application() instead.

@name can be any UTF-8 encoded string used to identify an
application.
@exec can have one of these two modifiers: &quot;\%f&quot;, which will
be expanded as the local file name retrieved from the bookmark&#039;s
URI; &quot;\%u&quot;, which will be expanded as the bookmark&#039;s URI.
The expansion is done automatically when retrieving the stored
command line using the g_bookmark_file_get_application_info() function.
@count is the number of times the application has registered the
bookmark; if is &amp;lt; 0, the current registration count will be increased
by one, if is 0, the application with @name will be removed from
the list of registered applications.
@stamp is the Unix time of the last registration; if it is -1, the
current time will be used.

If you try to remove an application by setting its registration count to
zero, and no bookmark for @uri is found, %FALSE is returned and
@error is set to %G_BOOKMARK_FILE_ERROR_URI_NOT_FOUND; similarly,
in the event that no application @name has registered a bookmark
for @uri,  %FALSE is returned and error is set to
%G_BOOKMARK_FILE_ERROR_APP_NOT_REGISTERED.  Otherwise, if no bookmark
for @uri is found, one is created.&lt;/doc&gt;

allocated and will eventually be freed with g_free().

Do not use it if @len is greater than %G_MAXUINT. #GByteArray
stores the length of its data in #guint, which may be shorter than
#gsize.&lt;/doc&gt;

           line=&quot;39&quot;&gt;A simple refcounted data type representing an immutable sequence of zero or
more bytes from an unspecified origin.

The purpose of a #GBytes is to keep the memory region that it holds
alive for as long as anyone holds a reference to the bytes.  When
the last reference count is dropped, the memory is released. Multiple
unrelated callers can use byte data in the #GBytes without coordinating
their activities, resting assured that the byte data will not change or
move while they hold a reference.

A #GBytes can come from many different origins that may have
different procedures for freeing the memory region.  Examples are
memory from g_malloc(), from memory slices, from a #GMappedFile or
memory from other allocators.

#GBytes work well as keys in #GHashTable. Use g_bytes_equal() and
g_bytes_hash() as parameters to g_hash_table_new() or g_hash_table_new_full().
#GBytes can also be used as keys in a #GTree by passing the g_bytes_compare()
function to g_tree_new().

The data pointed to by this bytes must not be modified. For a mutable
array of bytes see #GByteArray. Use g_bytes_unref_to_array() to create a
mutable array for a #GBytes sequence. To create an immutable #GBytes from
a mutable #GByteArray, use the g_byte_array_free_to_bytes() function.&lt;/doc&gt;

prefix of the longer one then the shorter one is considered to be less than
the longer one. Otherwise the first byte where both differ is used for
comparison. If @bytes1 has a smaller value at that position it is
considered less, otherwise greater than @bytes2.&lt;/doc&gt;

             line=&quot;542&quot;&gt;Gets a pointer to a region in @bytes.

The region starts at @offset many bytes from the start of the data
and contains @n_elements many elements of @element_size size.

@n_elements may be zero, but @element_size must always be non-zero.
Ideally, @element_size is a static constant (eg: sizeof a struct).

This function does careful bounds checking (including checking for
arithmetic overflows) and returns a non-%NULL pointer if the
specified region lies entirely within the @bytes. If the region is
in some way out of range, or if an overflow has occurred, then %NULL
is returned.

Note: it is possible to have a valid zero-size region. In this case,
the returned pointer will be equal to the base pointer of the data of
@bytes, plus @offset.  This will be non-%NULL except for the case
where @bytes itself was a zero-sized region.  Since it is unlikely
that you will be using this function to check for a zero-sized region
in a zero-sized @bytes, %NULL effectively always means &quot;error&quot;.&lt;/doc&gt;

Since 2.56, if @offset is 0 and @length matches the size of @bytes, then
@bytes will be returned with the reference count incremented by 1. If @bytes
is a slice of another #GBytes, then the resulting #GBytes will reference
the same #GBytes instead of @bytes. This allows consumers to simplify the

           line=&quot;35&quot;&gt;GLib provides a generic API for computing checksums (or ‘digests’)
for a sequence of arbitrary bytes, using various hashing algorithms
like MD5, SHA-1 and SHA-256. Checksums are commonly used in various
environments and specifications.

To create a new `GChecksum`, use [ctor@GLib.Checksum.new]. To free
a `GChecksum`, use [method@GLib.Checksum.free].

GLib supports incremental checksums using the `GChecksum` data
structure, by calling [method@GLib.Checksum.update] as long as there’s data
available and then using [method@GLib.Checksum.get_string] or
[method@GLib.Checksum.get_digest] to compute the checksum and return it
either as a string in hexadecimal form, or as a raw sequence of bytes. To
compute the checksum for binary blobs and nul-terminated strings in
one go, use the convenience functions [func@GLib.compute_checksum_for_data]
and [func@GLib.compute_checksum_for_string], respectively.&lt;/doc&gt;

             line=&quot;1449&quot;&gt;Creates a new #GChecksum, using the checksum algorithm @checksum_type.
If the @checksum_type is not known, %NULL is returned.
A #GChecksum can be used to compute the checksum, or digest, of an
arbitrary binary blob, using different hashing algorithms.

A #GChecksum works by feeding a binary blob through g_checksum_update()
until there is data to be checked; the digest can then be extracted
using g_checksum_get_string(), which will return the checksum as a
hexadecimal string; or g_checksum_get_digest(), which will return a
vector of raw bytes. Once either g_checksum_get_string() or
g_checksum_get_digest() have been called on a #GChecksum, the checksum
will be closed and it won&#039;t be possible to call g_checksum_update()
on it anymore.&lt;/doc&gt;

           line=&quot;46&quot;&gt;`GCompletion` provides support for automatic completion of a string
using any group of target strings. It is typically used for file
name completion as is common in many UNIX shells.

A `GCompletion` is created using [func@GLib.Completion.new]. Target items are
added and removed with [method@GLib.Completion.add_items],
[method@GLib.Completion.remove_items] and
[method@GLib.Completion.clear_items]. A completion attempt is requested with
[method@GLib.Completion.complete] or [method@GLib.Completion.complete_utf8].
When no longer needed, the `GCompletion` is freed with
[method@GLib.Completion.free].

Items in the completion can be simple strings (e.g. filenames), or
pointers to arbitrary data structures. If data structures are used
you must provide a [type@GLib.CompletionFunc] in [func@GLib.Completion.new],
which retrieves the item’s string from the data structure. You can change
the way in which strings are compared by setting a different
[type@GLib.CompletionStrncmpFunc] in [method@GLib.Completion.set_compare].

`GCompletion` has been marked as deprecated, since this API is rarely
used and not very actively maintained.&lt;/doc&gt;

           filename=&quot;glib/gthread.c&quot;
           line=&quot;305&quot;&gt;The #GCond struct is an opaque data structure that represents a
condition. Threads can block on a #GCond if they find a certain
condition to be false. If other threads change the state of this
condition they signal the #GCond, and that causes the waiting
threads to be woken up.

Consider the following example of a shared variable.  One or more
threads can wait for data to be published to the variable and when
another thread publishes the data, it can signal one of the waiting
threads to wake up to collect the data.

Here is an example for using GCond to block a thread until a condition
is satisfied:
|[&amp;lt;!-- language=&quot;C&quot; --&amp;gt;
  gpointer current_data = NULL;
  GMutex data_mutex;
  GCond data_cond;

  void
  push_data (gpointer data)
  {
    g_mutex_lock (&amp;amp;data_mutex);
    current_data = data;
    g_cond_signal (&amp;amp;data_cond);
    g_mutex_unlock (&amp;amp;data_mutex);
  }

  gpointer
  pop_data (void)
  {
    gpointer data;

    g_mutex_lock (&amp;amp;data_mutex);
    while (!current_data)
      g_cond_wait (&amp;amp;data_cond, &amp;amp;data_mutex);
    data = current_data;
    current_data = NULL;
    g_mutex_unlock (&amp;amp;data_mutex);

    return data;
  }
]|
Whenever a thread calls pop_data() now, it will wait until
current_data is non-%NULL, i.e. until some other thread
has called push_data().

The example shows that use of a condition variable must always be
paired with a mutex.  Without the use of a mutex, there would be a
race between the check of @current_data by the while loop in
pop_data() and waiting. Specifically, another thread could set
@current_data after the check, and signal the cond (with nobody
waiting on it) before the first thread goes to sleep. #GCond is
specifically useful for its ability to release the mutex and go
to sleep atomically.

It is also important to use the g_cond_wait() and g_cond_wait_until()
functions only inside a loop which checks for the condition to be
true.  See g_cond_wait() for an explanation of why the condition may
not be true even after it returns.

If a #GCond is allocated in static storage then it can be used
without initialisation.  Otherwise, you should call g_cond_init()
on it and g_cond_clear() when done.

A #GCond should only be accessed via the g_cond_ functions.&lt;/doc&gt;

until the time specified by @abs_time. The @mutex is unlocked before
falling asleep and locked again before resuming.

If @abs_time is %NULL, g_cond_timed_wait() acts like g_cond_wait().

This function can be used even if g_thread_init() has not yet been
called, and, in that case, will immediately return %TRUE.

To easily calculate @abs_time a combination of g_get_real_time()
and g_time_val_add() can be used.&lt;/doc&gt;

             line=&quot;768&quot;&gt;Atomically releases @mutex and waits until @cond is signalled.
When this function returns, @mutex is locked again and owned by the
calling thread.

When using condition variables, it is possible that a spurious wakeup
may occur (ie: g_cond_wait() returns even though g_cond_signal() was
not called).  It&#039;s also possible that a stolen wakeup may occur.
This is when g_cond_signal() is called, but another thread acquires
@mutex before this thread and modifies the state of the program in
such a way that when g_cond_wait() is able to return, the expected
condition is no longer met.

For this reason, g_cond_wait() must always be used in a loop.  See
the documentation for #GCond for a complete example.&lt;/doc&gt;

             line=&quot;834&quot;&gt;Waits until either @cond is signalled or @end_time has passed.

As with g_cond_wait() it is possible that a spurious or stolen wakeup
could occur.  For that reason, waiting on a condition variable should
always be in a loop, based on an explicitly-checked predicate.

%TRUE is returned if the condition variable was signalled (or in the
case of a spurious wakeup).  %FALSE is returned if @end_time has
passed.

The following code shows how to correctly perform a timed wait on a
condition variable (extending the example presented in the
documentation for #GCond):

|[&amp;lt;!-- language=&quot;C&quot; --&amp;gt;
gpointer
pop_data_timed (void)
{
  gint64 end_time;
  gpointer data;

  g_mutex_lock (&amp;amp;data_mutex);

  end_time = g_get_monotonic_time () + 5 * G_TIME_SPAN_SECOND;
  while (!current_data)
    if (!g_cond_wait_until (&amp;amp;data_cond, &amp;amp;data_mutex, end_time))
      {
        // timeout has passed.
        g_mutex_unlock (&amp;amp;data_mutex);
        return NULL;
      }

  // there is data for us
  data = current_data;
  current_data = NULL;

  g_mutex_unlock (&amp;amp;data_mutex);

  return data;
}
]|

Notice that the end time is calculated once, before entering the
loop and reused.  This is the motivation behind the use of absolute
time on this API -- if a relative time of 5 seconds were passed
directly to the call and a spurious wakeup occurred, the program would
have to start over waiting again (which would lead to a total wait
time of more than 5 seconds).&lt;/doc&gt;

           line=&quot;52&quot;&gt;A convenience macro which defines two functions. First, returning
the #GQuark for the extended error type @ErrorType; it is called
`error_type_quark()`. Second, returning the private data from a
passed #GError; it is called `error_type_get_private()`.

For this macro to work, a type named `ErrorTypePrivate` should be
defined, `error_type_private_init()`, `error_type_private_copy()`
and `error_type_private_clear()` functions need to be either
declared or defined. The functions should be similar to
#GErrorInitFunc, #GErrorCopyFunc and #GErrorClearFunc,
respectively, but they should receive the private data type instead
of #GError.

See [Extended #GError Domains][gerror-extended-domains] for an example.&lt;/doc&gt;

           line=&quot;62&quot;&gt;`GDate` is a struct for calendrical calculations.

The `GDate` data structure represents a day between January 1, Year 1,
and sometime a few thousand years in the future (right now it will go
to the year 65535 or so, but [method@GLib.Date.set_parse] only parses up to the
year 8000 or so - just count on &quot;a few thousand&quot;). `GDate` is meant to
represent everyday dates, not astronomical dates or historical dates
or ISO timestamps or the like. It extrapolates the current Gregorian
calendar forward and backward in time; there is no attempt to change
the calendar to match time periods or locations. `GDate` does not store
time information; it represents a day.

The `GDate` implementation has several nice features; it is only a
64-bit struct, so storing large numbers of dates is very efficient. It
can keep both a Julian and day-month-year representation of the date,
since some calculations are much easier with one representation or the
other. A Julian representation is simply a count of days since some
fixed day in the past; for #GDate the fixed day is January 1, 1 AD.
(&quot;Julian&quot; dates in the #GDate API aren&#039;t really Julian dates in the
technical sense; technically, Julian dates count from the start of the
Julian period, Jan 1, 4713 BC).

`GDate` is simple to use. First you need a &quot;blank&quot; date; you can get a
dynamically allocated date from [ctor@GLib.Date.new], or you can declare an
automatic variable or array and initialize it by calling [method@GLib.Date.clear].
A cleared date is safe; it&#039;s safe to call [method@GLib.Date.set_dmy] and the other
mutator functions to initialize the value of a cleared date. However, a cleared date
is initially invalid, meaning that it doesn&#039;t represent a day that exists.
It is undefined to call any of the date calculation routines on an invalid date.
If you obtain a date from a user or other unpredictable source, you should check
its validity with the [method@GLib.Date.valid] predicate. [method@GLib.Date.valid]
is also used to check for errors with [method@GLib.Date.set_parse] and other functions
that can fail. Dates can be invalidated by calling [method@GLib.Date.clear] again.

It is very important to use the API to access the `GDate` struct. Often only the
day-month-year or only the Julian representation is valid. Sometimes neither is valid.
Use the API.

GLib also features `GDateTime` which represents a precise time.&lt;/doc&gt;

Works just like the platform&#039;s C library strftime() function,
but only accepts date-related formats; time-related formats
give undefined results. Date must be valid. Unlike strftime()
(which uses the locale encoding), works on a UTF-8 format
string and stores a UTF-8 result.

This function does not provide any conversion specifiers in
addition to those implemented by the platform&#039;s C library.
For example, don&#039;t expect that using g_date_strftime() would
make the \%F provided by the C99 strftime() work on Windows
where the C library only complies to C89.&lt;/doc&gt;

           line=&quot;91&quot;&gt;`GDateTime` is a structure that combines a Gregorian date and time
into a single structure.

`GDateTime` provides many conversion and methods to manipulate dates and times.
Time precision is provided down to microseconds and the time can range
(proleptically) from 0001-01-01 00:00:00 to 9999-12-31 23:59:59.999999.
`GDateTime` follows POSIX time in the sense that it is oblivious to leap
seconds.

`GDateTime` is an immutable object; once it has been created it cannot
be modified further. All modifiers will create a new `GDateTime`.
Nearly all such functions can fail due to the date or time going out
of range, in which case %NULL will be returned.

`GDateTime` is reference counted: the reference count is increased by calling
[method@GLib.DateTime.ref] and decreased by calling [method@GLib.DateTime.unref].
When the reference count drops to 0, the resources allocated by the `GDateTime`
structure are released.

Many parts of the API may produce non-obvious results. As an
example, adding two months to January 31st will yield March 31st
whereas adding one month and then one month again will yield either
March 28th or March 29th.  Also note that adding 24 hours is not
always the same as adding one day (since days containing daylight
savings time transitions are either 23 or 25 hours in length).&lt;/doc&gt;
      &lt;source-position filename=&quot;glib/gdatetime.h&quot; line=&quot;122&quot;/&gt;
      &lt;constructor name=&quot;new&quot; c:identifier=&quot;g_date_time_new&quot; version=&quot;2.26&quot;&gt;
        &lt;doc xml:space=&quot;preserve&quot;
             filename=&quot;glib/gdatetime.c&quot;
             line=&quot;1589&quot;&gt;Creates a new #GDateTime corresponding to the given date and time in
the time zone @tz.

The @year must be between 1 and 9999, @month between 1 and 12 and @day
between 1 and 28, 29, 30 or 31 depending on the month and the year.

@hour must be between 0 and 23 and @minute must be between 0 and 59.

@seconds must be at least 0.0 and must be strictly less than 60.0.
It will be rounded down to the nearest microsecond.

If the given time is not representable in the given time zone (for
example, 02:30 on March 14th 2010 in Toronto, due to daylight savings
time) then the time will be rounded up to the nearest existing time
(in this case, 03:00).  If this matters to you then you should verify
the return value for containing the same as the numbers you gave.

In the case that the given time is ambiguous in the given time zone
(for example, 01:30 on November 7th 2010 in Toronto, due to daylight
savings time) then the time falling within standard (ie:
non-daylight) time is taken.

It not considered a programmer error for the values to this function
to be out of range, but in the case that they are, the function will
return %NULL.

You should release the return value by calling g_date_time_unref()
when you are done with it.&lt;/doc&gt;

[ISO 8601 formatted string](https://en.wikipedia.org/wiki/ISO_8601)
@text. ISO 8601 strings of the form &amp;lt;date&amp;gt;&amp;lt;sep&amp;gt;&amp;lt;time&amp;gt;&amp;lt;tz&amp;gt; are supported, with
some extensions from [RFC 3339](https://tools.ietf.org/html/rfc3339) as
mentioned below.

Note that as #GDateTime &quot;is oblivious to leap seconds&quot;, leap seconds information
in an ISO-8601 string will be ignored, so a `23:59:60` time would be parsed as
`23:59:59`.

&amp;lt;sep&amp;gt; is the separator and can be either &#039;T&#039;, &#039;t&#039; or &#039; &#039;. The latter two
separators are an extension from
[RFC 3339](https://tools.ietf.org/html/rfc3339#section-5.6).

&amp;lt;date&amp;gt; is in the form:

- `YYYY-MM-DD` - Year/month/day, e.g. 2016-08-24.
- `YYYYMMDD` - Same as above without dividers.
- `YYYY-DDD` - Ordinal day where DDD is from 001 to 366, e.g. 2016-237.
- `YYYYDDD` - Same as above without dividers.
- `YYYY-Www-D` - Week day where ww is from 01 to 52 and D from 1-7,
  e.g. 2016-W34-3.
- `YYYYWwwD` - Same as above without dividers.

&amp;lt;time&amp;gt; is in the form:

- `hh:mm:ss(.sss)` - Hours, minutes, seconds (subseconds), e.g. 22:10:42.123.
- `hhmmss(.sss)` - Same as above without dividers.

&amp;lt;tz&amp;gt; is an optional timezone suffix of the form:

- `Z` - UTC.
- `+hh:mm` or `-hh:mm` - Offset from UTC in hours and minutes, e.g. +12:00.
- `+hh` or `-hh` - Offset from UTC in hours, e.g. +12.

If the timezone is not provided in @text it must be provided in @default_tz
(this field is otherwise ignored).

This call can fail (returning %NULL) if @text is not a valid ISO 8601
formatted string.

You should release the return value by calling g_date_time_unref()
when you are done with it.&lt;/doc&gt;

             line=&quot;3657&quot;&gt;Creates a newly allocated string representing the requested @format.

The format strings understood by this function are a subset of the
`strftime()` format language as specified by C99.  The `%D`, `%U` and `%W`
conversions are not supported, nor is the `E` modifier.  The GNU
extensions `%k`, `%l`, `%s` and `%P` are supported, however, as are the
`0`, `_` and `-` modifiers. The Python extension `%f` is also supported.

In contrast to `strftime()`, this function always produces a UTF-8
string, regardless of the current locale.  Note that the rendering of
many formats is locale-dependent and may not match the `strftime()`
output exactly.

The following format specifiers are supported:

- `%a`: the abbreviated weekday name according to the current locale
- `%A`: the full weekday name according to the current locale
- `%b`: the abbreviated month name according to the current locale
- `%B`: the full month name according to the current locale
- `%c`: the preferred date and time representation for the current locale
- `%C`: the century number (year/100) as a 2-digit integer (00-99)
- `%d`: the day of the month as a decimal number (range 01 to 31)
- `%e`: the day of the month as a decimal number (range 1 to 31);
  single digits are preceded by a figure space (U+2007)
- `%F`: equivalent to `%Y-%m-%d` (the ISO 8601 date format)
- `%g`: the last two digits of the ISO 8601 week-based year as a
  decimal number (00-99). This works well with `%V` and `%u`.
- `%G`: the ISO 8601 week-based year as a decimal number. This works
  well with `%V` and `%u`.
- `%h`: equivalent to `%b`
- `%H`: the hour as a decimal number using a 24-hour clock (range 00 to 23)
- `%I`: the hour as a decimal number using a 12-hour clock (range 01 to 12)
- `%j`: the day of the year as a decimal number (range 001 to 366)
- `%k`: the hour (24-hour clock) as a decimal number (range 0 to 23);
  single digits are preceded by a figure space (U+2007)
- `%l`: the hour (12-hour clock) as a decimal number (range 1 to 12);
  single digits are preceded by a figure space (U+2007)
- `%m`: the month as a decimal number (range 01 to 12)
- `%M`: the minute as a decimal number (range 00 to 59)
- `%f`: the microsecond as a decimal number (range 000000 to 999999)
- `%p`: either ‘AM’ or ‘PM’ according to the given time value, or the
  corresponding  strings for the current locale.  Noon is treated as
  ‘PM’ and midnight as ‘AM’. Use of this format specifier is discouraged, as
  many locales have no concept of AM/PM formatting. Use `%c` or `%X` instead.
- `%P`: like `%p` but lowercase: ‘am’ or ‘pm’ or a corresponding string for
  the current locale. Use of this format specifier is discouraged, as
  many locales have no concept of AM/PM formatting. Use `%c` or `%X` instead.
- `%r`: the time in a.m. or p.m. notation. Use of this format specifier is
  discouraged, as many locales have no concept of AM/PM formatting. Use `%c`
  or `%X` instead.
- `%R`: the time in 24-hour notation (`%H:%M`)
- `%s`: the number of seconds since the Epoch, that is, since 1970-01-01
  00:00:00 UTC
- `%S`: the second as a decimal number (range 00 to 60)
- `%t`: a tab character
- `%T`: the time in 24-hour notation with seconds (`%H:%M:%S`)
- `%u`: the ISO 8601 standard day of the week as a decimal, range 1 to 7,
   Monday being 1. This works well with `%G` and `%V`.
- `%V`: the ISO 8601 standard week number of the current year as a decimal
  number, range 01 to 53, where week 1 is the first week that has at
  least 4 days in the new year. See g_date_time_get_week_of_year().
  This works well with `%G` and `%u`.
- `%w`: the day of the week as a decimal, range 0 to 6, Sunday being 0.
  This is not the ISO 8601 standard format — use `%u` instead.
- `%x`: the preferred date representation for the current locale without
  the time
- `%X`: the preferred time representation for the current locale without
  the date
- `%y`: the year as a decimal number without the century
- `%Y`: the year as a decimal number including the century
- `%z`: the time zone as an offset from UTC (`+hhmm`)
- `%:z`: the time zone as an offset from UTC (`+hh:mm`).
  This is a gnulib `strftime()` extension. Since: 2.38
- `%::z`: the time zone as an offset from UTC (`+hh:mm:ss`). This is a
  gnulib `strftime()` extension. Since: 2.38
- `%:::z`: the time zone as an offset from UTC, with `:` to necessary
  precision (e.g., `-04`, `+05:30`). This is a gnulib `strftime()` extension. Since: 2.38
- `%Z`: the time zone or name or abbreviation
- `%%`: a literal `%` character

Some conversion specifications can be modified by preceding the
conversion specifier by one or more modifier characters.

The following modifiers are supported for many of the numeric
conversions:

- `O`: Use alternative numeric symbols, if the current locale supports those.
- `_`: Pad a numeric result with spaces. This overrides the default padding
  for the specifier.
- `-`: Do not pad a numeric result. This overrides the default padding
  for the specifier.
- `0`: Pad a numeric result with zeros. This overrides the default padding
  for the specifier.

The following modifiers are supported for many of the alphabetic conversions:

- `^`: Use upper case if possible. This is a gnulib `strftime()` extension.
  Since: 2.80
- `#`: Use opposite case if possible. This is a gnulib `strftime()`
  extension. Since: 2.80

Additionally, when `O` is used with `B`, `b`, or `h`, it produces the alternative
form of a month name. The alternative form should be used when the month
name is used without a day number (e.g., standalone). It is required in
some languages (Baltic, Slavic, Greek, and more) due to their grammatical
rules. For other languages there is no difference. `%OB` is a GNU and BSD
`strftime()` extension expected to be added to the future POSIX specification,
`%Ob` and `%Oh` are GNU `strftime()` extensions. Since: 2.56

Since GLib 2.80, when `E` is used with `%c`, `%C`, `%x`, `%X`, `%y` or `%Y`,
the date is formatted using an alternate era representation specific to the
locale. This is typically used for the Thai solar calendar or Japanese era
names, for example.

- `%Ec`: the preferred date and time representation for the current locale,
  using the alternate era representation
- `%EC`: the name of the era
- `%Ex`: the preferred date representation for the current locale without
  the time, using the alternate era representation
- `%EX`: the preferred time representation for the current locale without
  the date, using the alternate era representation
- `%Ey`: the year since the beginning of the era denoted by the `%EC`
  specifier
- `%EY`: the full alternative year representation&lt;/doc&gt;

             line=&quot;2361&quot;&gt;Returns the ISO 8601 week-numbering year in which the week containing
@datetime falls.

This function, taken together with g_date_time_get_week_of_year() and
g_date_time_get_day_of_week() can be used to determine the full ISO
week date on which @datetime falls.

This is usually equal to the normal Gregorian year (as returned by
g_date_time_get_year()), except as detailed below:

For Thursday, the week-numbering year is always equal to the usual
calendar year.  For other days, the number is such that every day
within a complete week (Monday to Sunday) is contained within the
same week-numbering year.

For Monday, Tuesday and Wednesday occurring near the end of the year,
this may mean that the week-numbering year is one greater than the
calendar year (so that these days have the same week-numbering year
as the Thursday occurring early in the next year).

For Friday, Saturday and Sunday occurring near the start of the year,
this may mean that the week-numbering year is one less than the
calendar year (so that these days have the same week-numbering year
as the Thursday occurring late in the previous year).

An equivalent description is that the week-numbering year is equal to
the calendar year containing the majority of the days in the current
week (Monday to Sunday).

Note that January 1 0001 in the proleptic Gregorian calendar is a
Monday, so this function never returns 0.&lt;/doc&gt;

             line=&quot;2437&quot;&gt;Returns the ISO 8601 week number for the week containing @datetime.
The ISO 8601 week number is the same for every day of the week (from
Moday through Sunday).  That can produce some unusual results
(described below).

The first week of the year is week 1.  This is the week that contains
the first Thursday of the year.  Equivalently, this is the first week
that has more than 4 of its days falling within the calendar year.

The value 0 is never returned by this function.  Days contained
within a year but occurring before the first ISO 8601 week of that
year are considered as being contained in the last week of the
previous year.  Similarly, the final days of a calendar year may be
considered as being part of the first ISO 8601 week of the next year
if 4 or more days of that week are contained within the new year.&lt;/doc&gt;

The time contained in a #GTimeVal is always stored in the form of

zone associated with @datetime.

On systems where &#039;long&#039; is 32bit (ie: all 32bit systems and all
Windows systems), a #GTimeVal is incapable of storing the entire
range of values that #GDateTime is capable of expressing.  On those
systems, this function returns %FALSE to indicate that the time is
out of range.

On systems where &#039;long&#039; is 64bit, this function never fails.&lt;/doc&gt;

%NULL may also be returned in case of errors. On Unix, you can
check `errno` to find out if %NULL was returned because of an error.

On Unix, the &#039;.&#039; and &#039;..&#039; entries are omitted, and the returned

If @domain contains a `FAILED` (or otherwise generic) error code,
you should generally not check for it explicitly, but should
instead treat any not-explicitly-recognized error code as being
equivalent to the `FAILED` code. This way, if the domain is
extended in the future to provide a more specific error code for
a certain case, your code will still work.&lt;/doc&gt;

@error_type_name should not be freed. @error_type_private_size must
be greater than 0.

@error_type_init receives an initialized #GError and should then initialize
the private data.

@error_type_copy is a function that receives both original and a copy
#GError and should copy the fields of the private error data. The standard
#GError fields are already handled.

@error_type_clear receives the pointer to the error, and it should free the
fields of the private error data. It should not free the struct itself though.

already takes care of passing valid information to this function.&lt;/doc&gt;

           line=&quot;74&quot;&gt;Specifies the type of the hash function which is passed to
g_hash_table_new() when a #GHashTable is created.

The function is passed a key and should return a #guint hash value.
The functions g_direct_hash(), g_int_hash() and g_str_hash() provide
hash functions which can be used when the key is a #gpointer, #gint*,
and #gchar* respectively.

g_direct_hash() is also the appropriate hash function for keys
of the form `GINT_TO_POINTER (n)` (or similar macros).

A good hash functions should produce
hash values that are evenly distributed over a fairly large range.
The modulus is taken with the hash table size (a prime number) to
find the &#039;bucket&#039; to place each key into. The function should also
be very fast, since it is called for each key lookup.

Note that the hash functions provided by GLib have these qualities,
but are not particularly robust against manufactured keys that
cause hash collisions. Therefore, you should consider choosing
a more secure hash function when using a GHashTable with keys
that originate in untrusted data (such as HTTP requests).
Using g_str_hash() in that situation might make your application
vulnerable to
[Algorithmic Complexity Attacks](https://lwn.net/Articles/474912/).

The key to choosing a good hash is unpredictability.  Even
cryptographic hashes are very easy to find collisions for when the
remainder is taken modulo a somewhat predictable prime number.  There
must be an element of randomness that an attacker is unable to guess.&lt;/doc&gt;

is equivalent to calling g_hash_table_replace() with @key as both the
key and the value.

In particular, this means that if @key already exists in the hash table, then
the old copy of @key in the hash table is freed and @key replaces it in the
table.

When a hash table only ever contains keys that have themselves as the
corresponding value it is able to be stored more efficiently.  See
the discussion in the section description.

Starting from GLib 2.40, this function returns a boolean value to
indicate whether the newly added value was already in the hash table

g_hash_table_find() or g_hash_table_foreach() (e.g. in the order of

to use additional or different data structures for reverse lookups
(keep in mind that an O(n) find/foreach operation issued for all n
values in a hash table ends up needing O(n*n) operations).&lt;/doc&gt;

The returned array is %NULL-terminated but may contain %NULL as a
key.  Use @length to determine the true length if it&#039;s possible that
%NULL was used as the value for a key.

Note: in the common case of a string-keyed #GHashTable, the return
value of this function can be conveniently cast to (const gchar **).

This iterates over every entry in the hash table to build its return value.
To iterate over the entries in a #GHashTable more efficiently, use a
#GHashTableIter.

You should always free the return result with g_free().  In the
above-mentioned case of a string-keyed hash table, it may be
appropriate to use g_strfreev() if you call g_hash_table_steal_all()
first to transfer ownership of the keys.&lt;/doc&gt;

Hash values returned by @hash_func are used to determine where keys
are stored within the #GHashTable data structure. The g_direct_hash(),
g_int_hash(), g_int64_hash(), g_double_hash() and g_str_hash()
functions are provided for some common types of keys.
If @hash_func is %NULL, g_direct_hash() is used.

@key_equal_func is used when looking up keys in the #GHashTable.
The g_direct_equal(), g_int_equal(), g_int64_equal(), g_double_equal()
and g_str_equal() functions are provided for the most common types
of keys. If @key_equal_func is %NULL, keys are compared directly in
a similar fashion to g_direct_equal(), but without the overhead of
a function call. @key_equal_func is called with the key from the hash table
as its first parameter, and the user-provided key to check against as
its second.&lt;/doc&gt;

recursively remove further items from the hash table. This is only
permissible if the application still holds a reference to the hash table.
This means that you may need to ensure that the hash table is empty by
calling g_hash_table_remove_all() before releasing the last reference using
g_hash_table_unref().&lt;/doc&gt;

If found, the stolen key and value are removed from the hash table without
calling the key and value destroy functions, and ownership is transferred to
the caller of this method, as with g_hash_table_steal(). That is the case
regardless whether @stolen_key or @stolen_value output parameters are
requested.

You can pass %NULL for @lookup_key, provided the hash and equal functions
of @hash_table are %NULL-safe.

The dictionary implementation optimizes for having all values identical to
their keys, for example by using g_hash_table_add(). When stealing both the
key and the value from such a dictionary, the value will be %NULL.&lt;/doc&gt;

uses algorithms like SHA1 in a secure way to produce a digest of a
key and data.

Both the key and data are arbitrary byte arrays of bytes or characters.

Support for HMAC Digests has been added in GLib 2.30, and support for SHA-512
in GLib 2.42. Support for SHA-384 was added in GLib 2.52.

To create a new `GHmac`, use [ctor@GLib.Hmac.new]. To free a `GHmac`, use
[method@GLib.Hmac.unref].&lt;/doc&gt;

             line=&quot;69&quot;&gt;Creates a new #GHmac, using the digest algorithm @digest_type.
If the @digest_type is not known, %NULL is returned.
A #GHmac can be used to compute the HMAC of a key and an
arbitrary binary blob, using different hashing algorithms.

A #GHmac works by feeding a binary blob through g_hmac_update()
until the data is complete; the digest can then be extracted
using g_hmac_get_string(), which will return the checksum as a
hexadecimal string; or g_hmac_get_digest(), which will return a
array of raw bytes. Once either g_hmac_get_string() or
g_hmac_get_digest() have been called on a #GHmac, the HMAC
will be closed and it won&#039;t be possible to call g_hmac_update()
on it anymore.

Support for digests of type %G_CHECKSUM_SHA512 has been added in GLib 2.42.
Support for %G_CHECKSUM_SHA384 was added in GLib 2.52.&lt;/doc&gt;

set, is implementation defined. This function may return success (with a

           line=&quot;46&quot;&gt;The `GIOChannel` data type aims to provide a portable method for
using file descriptors, pipes, and sockets, and integrating them
into the main event loop (see [struct@GLib.MainContext]). Currently,
full support is available on UNIX platforms; support for Windows
is only partially complete.

To create a new `GIOChannel` on UNIX systems use
[ctor@GLib.IOChannel.unix_new]. This works for plain file descriptors,
pipes and sockets. Alternatively, a channel can be created for a
file in a system independent manner using [ctor@GLib.IOChannel.new_file].

Once a `GIOChannel` has been created, it can be used in a generic
manner with the functions [method@GLib.IOChannel.read_chars],
[method@GLib.IOChannel.write_chars], [method@GLib.IOChannel.seek_position],
and [method@GLib.IOChannel.shutdown].

To add a `GIOChannel` to the main event loop, use [func@GLib.io_add_watch] or
[func@GLib.io_add_watch_full]. Here you specify which events you are
interested in on the `GIOChannel`, and provide a function to be called
whenever these events occur.

`GIOChannel` instances are created with an initial reference count of 1.
[method@GLib.IOChannel.ref] and [method@GLib.IOChannel.unref] can be used to
increment or decrement the reference count respectively. When the
reference count falls to 0, the `GIOChannel` is freed. (Though it
isn’t closed automatically, unless it was created using
[ctor@GLib.IOChannel.new_file].) Using [func@GLib.io_add_watch] or
[func@GLib.io_add_watch_full] increments a channel’s reference count.

The new functions [method@GLib.IOChannel.read_chars],
[method@GLib.IOChannel.read_line], [method@GLib.IOChannel.read_line_string],
[method@GLib.IOChannel.read_to_end], [method@GLib.IOChannel.write_chars],
[method@GLib.IOChannel.seek_position], and [method@GLib.IOChannel.flush]
should not be mixed with the deprecated functions
[method@GLib.IOChannel.read], [method@GLib.IOChannel.write], and
[method@GLib.IOChannel.seek] on the same channel.&lt;/doc&gt;

             line=&quot;587&quot;&gt;Creates a new #GIOChannel given a file descriptor. On UNIX systems
this works for plain files, pipes, and sockets.

The returned #GIOChannel has a reference count of 1.

The default encoding for #GIOChannel is UTF-8. If your application
is reading output from a command using via pipe, you may need to set
the encoding to the encoding of the current locale (see
g_get_charset()) with the g_io_channel_set_encoding() function.
By default, the fd passed will not be closed when the final reference
to the #GIOChannel data structure is dropped.

If you want to read raw binary data without interpretation, then
call the g_io_channel_set_encoding() function with %NULL for the
encoding argument.

This function is available in GLib on Windows, too, but you should
avoid using it on Windows. The domain of file descriptors and
sockets overlap. There is no way for GLib to know which one you mean
in case the argument you pass to this function happens to be both a
valid file descriptor and socket. If that happens a warning is
issued, and GLib assumes that it is the file descriptor you mean.&lt;/doc&gt;

of a socket with the UNIX shutdown() function), the user
should immediately call g_io_channel_get_flags() to update
the internal values of these flags.&lt;/doc&gt;

is %NULL. For any other encoding, the channel must be buffered.

A buffered channel can only be set unbuffered if the channel&#039;s
internal buffers have been flushed. Newly created channels or
channels which have returned %G_IO_STATUS_EOF
not require such a flush. For write-only channels, a call to
g_io_channel_flush () is sufficient. For all other channels,
the buffers may be flushed by a call to g_io_channel_seek_position ().
This includes the possibility of seeking with seek type %G_SEEK_CUR
and an offset of zero. Note that this means that socket-based
channels cannot be set unbuffered once they have had data
read from them.

On unbuffered channels, it is safe to mix read and write
calls from the new and old APIs, if this is necessary for
maintaining old code.

The default state of the channel is buffered.&lt;/doc&gt;

             line=&quot;1269&quot;&gt;Sets the encoding for the input/output of the channel.
The internal encoding is always UTF-8. The default encoding
for the external file is UTF-8.

The encoding %NULL is safe to use with binary data.

The encoding can only be set if one of the following conditions
is true:

- The channel was just created, and has not been written to or read from yet.

- The channel is write-only.

- The channel is a file, and the file pointer was just repositioned
  by a call to g_io_channel_seek_position(). (This flushes all the
  internal buffers.)

- The current encoding is %NULL or UTF-8.

- One of the (new API) read functions has just returned %G_IO_STATUS_EOF
  (or, in the case of g_io_channel_read_to_end(), %G_IO_STATUS_NORMAL).

-  One of the functions g_io_channel_read_chars() or
   g_io_channel_read_unichar() has returned %G_IO_STATUS_AGAIN or
   %G_IO_STATUS_ERROR. This may be useful in the case of
   %G_CONVERT_ERROR_ILLEGAL_SEQUENCE.
   Returning one of these statuses from g_io_channel_read_line(),
   g_io_channel_read_line_string(), or g_io_channel_read_to_end()
   does not guarantee that the encoding can be changed.

Channels which do not meet one of the above conditions cannot call
g_io_channel_seek_position() with an offset of %G_SEEK_CUR, and, if
they are &quot;seekable&quot;, cannot call g_io_channel_write_chars() after
calling one of the API &quot;read&quot; functions.&lt;/doc&gt;

`GKeyFile` lets you parse, edit or create files containing groups of
key-value pairs, which we call &quot;key files&quot; for lack of a better name.
Several freedesktop.org specifications use key files now, e.g the
[Desktop Entry Specification](http://freedesktop.org/Standards/desktop-entry-spec)
and the [Icon Theme Specification](http://freedesktop.org/Standards/icon-theme-spec).

The syntax of key files is described in detail in the
[Desktop Entry Specification](http://freedesktop.org/Standards/desktop-entry-spec),
here is a quick summary: Key files consists of groups of key-value pairs, interspersed
with comments.

```txt
# this is just an example
# there can be comments before the first group

[First Group]

Name=Key File Example\tthis value shows\nescaping

# localized strings are stored in multiple key-value pairs
Welcome=Hello
Welcome[de]=Hallo
Welcome[fr_FR]=Bonjour
Welcome[it]=Ciao

[Another Group]

Numbers=2;20;-200;0

Booleans=true;false;true;true
```

Lines beginning with a &#039;#&#039; and blank lines are considered comments.

Groups are started by a header line containing the group name enclosed
in &#039;[&#039; and &#039;]&#039;, and ended implicitly by the start of the next group or
the end of the file. Each key-value pair must be contained in a group.

Key-value pairs generally have the form `key=value`, with the exception
of localized strings, which have the form `key[locale]=value`, with a
locale identifier of the form `lang_COUNTRY@MODIFIER` where `COUNTRY`
and `MODIFIER` are optional. Space before and after the &#039;=&#039; character
are ignored. Newline, tab, carriage return and backslash characters in
value are escaped as `\n`, `\t`, `\r`, and `\\\\`, respectively. To preserve
leading spaces in values, these can also be escaped as `\s`.

Key files can store strings (possibly with localized variants), integers,
booleans and lists of these. Lists are separated by a separator character,
typically &#039;;&#039; or &#039;,&#039;. To use the list separator character in a value in
a list, it has to be escaped by prefixing it with a backslash.

This syntax is obviously inspired by the .ini files commonly met
on Windows, but there are some important differences:

- .ini files use the &#039;;&#039; character to begin comments,
  key files use the &#039;#&#039; character.

- Key files do not allow for ungrouped keys meaning only
  comments can precede the first group.

- Key files are always encoded in UTF-8.

- Key and Group names are case-sensitive. For example, a group called
  [GROUP] is a different from [group].

- .ini files don&#039;t have a strongly typed boolean entry type,
   they only have GetProfileInt(). In key files, only
   true and false (in lower case) are allowed.

Note that in contrast to the
[Desktop Entry Specification](http://freedesktop.org/Standards/desktop-entry-spec),
groups in key files may contain the same key multiple times; the last entry wins.
Key files may also contain multiple groups with the same name; they are merged
together. Another difference is that keys and group names in key files are not
restricted to ASCII characters.

Here is an example of loading a key file and reading a value:

```c
g_autoptr(GError) error = NULL;
g_autoptr(GKeyFile) key_file = g_key_file_new ();

if (!g_key_file_load_from_file (key_file, &quot;key-file.ini&quot;, flags, &amp;amp;error))
  {
    if (!g_error_matches (error, G_FILE_ERROR, G_FILE_ERROR_NOENT))
      g_warning (&quot;Error loading key file: %s&quot;, error-&amp;gt;message);
    return;

the return value both carries meaning and signals an error.  To use
this function, you must pass a #GError pointer in @error, and check
whether it is not %NULL to see if an error occurred.

%G_LOCK_DEFINE defines a lock. It can appear in any place where
variable definitions may appear in programs, i.e. in the first block
of a function or outside of functions. The @name parameter will be
mangled to get the name of the #GMutex. This means that you
can use names of existing variables as the parameter - e.g. the name
of the variable you intend to protect with the lock. Look at our
give_me_next_number() example using the `G_LOCK` macros:

Here is an example for using the `G_LOCK` convenience macros:

|[&amp;lt;!-- language=&quot;C&quot; --&amp;gt;
  G_LOCK_DEFINE (current_number);

  int
  give_me_next_number (void)
  {
    static int current_number = 0;
    int ret_val;

    G_LOCK (current_number);
    ret_val = current_number = calc_next_number (current_number);
    G_UNLOCK (current_number);

           line=&quot;91&quot;&gt;Defines the log domain. See [Log Domains](#log-domains).

Libraries should define this so that any messages
which they log can be differentiated from messages from other
libraries and application code. But be careful not to define
it in any public header files.

Log domains must be unique, and it is recommended that they are the
application or library name, optionally followed by a hyphen and a sub-domain
name. For example, `bloatpad` or `bloatpad-io`.

If undefined, it defaults to the default %NULL (or `&quot;&quot;`) log domain; this is
not advisable, as it cannot be filtered against using the `G_MESSAGES_DEBUG`
environment variable.

For example, GTK uses this in its `Makefile.am`:
|[
AM_CPPFLAGS = -DG_LOG_DOMAIN=\&quot;Gtk\&quot;
]|

Applications can choose to leave it as the default %NULL (or `&quot;&quot;`)
domain. However, defining the domain offers the same advantages as
above.&lt;/doc&gt;

Note that the return value is the new start of the list,

g_list_append() has to traverse the entire list to find the end,
which is inefficient when adding multiple elements. A common idiom
to avoid the inefficiency is to use g_list_prepend() and reverse
the list with g_list_reverse() when all elements have been added.

|[&amp;lt;!-- language=&quot;C&quot; --&amp;gt;
// Notice that these are initialized to the empty list.
GList *string_list = NULL, *number_list = NULL;

// This is a list of strings.
string_list = g_list_append (string_list, &quot;first&quot;);
string_list = g_list_append (string_list, &quot;second&quot;);

// This is a list of integers.
number_list = g_list_append (number_list, GINT_TO_POINTER (27));
number_list = g_list_append (number_list, GINT_TO_POINTER (14));

             line=&quot;634&quot;&gt;Makes a full (deep) copy of a #GList.

In contrast with g_list_copy(), this function uses @func to make
a copy of each list element, in addition to copying the list
container itself.

@func, as a #GCopyFunc, takes two arguments, the data to be copied
and a @user_data pointer. On common processor architectures, it&#039;s safe to
pass %NULL as @user_data if the copy function takes only one argument. You
may get compiler warnings from this though if compiling with GCC’s
`-Wcast-function-type` warning.

For instance, if @list holds a list of GObjects, you can do:
|[&amp;lt;!-- language=&quot;C&quot; --&amp;gt;
another_list = g_list_copy_deep (list, (GCopyFunc) g_object_ref, NULL);
]|

And, to entirely free the new list, you could do:
|[&amp;lt;!-- language=&quot;C&quot; --&amp;gt;
g_list_free_full (another_list, g_object_unref);

The default log handler, [func@GLib.log_default_handler], automatically appends a
new-line character to @message when printing it. It is advised that any
custom log handler functions behave similarly, so that logging calls in user
code do not need modifying to add a new-line character to the message if the
log handler is changed.

This is not used if structured logging is enabled; see
[Using Structured Logging](logging.html#using-structured-logging).&lt;/doc&gt;

           line=&quot;166&quot;&gt;Writer function for log entries. A log entry is a collection of one or more
#GLogFields, using the standard [field names from journal
specification](https://www.freedesktop.org/software/systemd/man/systemd.journal-fields.html).
See g_log_structured() for more information.

Writer functions must ignore fields which they do not recognise, unless they
can write arbitrary binary output, as field values may be arbitrary binary.

@log_level is guaranteed to be included in @fields as the `PRIORITY` field,
but is provided separately for convenience of deciding whether or where to
output the log entry.

Writer functions should return %G_LOG_WRITER_HANDLED if they handled the log
message successfully or if they deliberately ignored it. If there was an
error handling the message (for example, if the writer function is meant to
send messages to a remote logging server and there is a network error), it
should return %G_LOG_WRITER_UNHANDLED. This allows writer functions to be
chained and fall back to simpler handlers in case of failure.&lt;/doc&gt;

This feature is only supported on GCC and clang. This macro is not defined on

`-Wdeclaration-after-statement` is used, or C standard prior to C99.

It is a programmer error to attempt to look up a non-existent source.

More specifically: source IDs can be reissued after a source has been
destroyed and therefore it is never valid to use this function with a
source ID which may have already been removed.  An example is when
scheduling an idle to run in another thread with g_idle_add(): the
idle may already have run and been removed by the time this function
is called on its (now invalid) source ID.  This source ID may have
been reissued, leading to the operation being performed against the
wrong source.&lt;/doc&gt;

invocation of @function.

If @context is %NULL then the global-default main context — as
returned by g_main_context_default() — is used.

If @context is owned by the current thread, @function is called
directly.  Otherwise, if @context is the thread-default main context
of the current thread and g_main_context_acquire() succeeds, then
@function is called and g_main_context_release() is called
afterwards.

In any other case, an idle source is created to call @function and
that source is attached to @context (presumably to be run in another
thread).  The idle source is attached with %G_PRIORITY_DEFAULT
priority.  If you want a different priority, use
g_main_context_invoke_full().

Note that, as with normal idle functions, @function should probably
return %FALSE.  If it returns %TRUE, it will be continuously run in a
loop (and may prevent this call from returning).&lt;/doc&gt;

             line=&quot;729&quot;&gt;Acquires @context and sets it as the thread-default context for the
current thread. This will cause certain asynchronous operations
(such as most [gio][gio]-based I/O) which are
started in this thread to run under @context and deliver their
results to its main loop, rather than running under the global
default main context in the main thread. Note that calling this function
changes the context returned by g_main_context_get_thread_default(),
not the one returned by g_main_context_default(), so it does not affect
the context used by functions like g_idle_add().

Normally you would call this function shortly after creating a new
thread, passing it a #GMainContext which will be run by a
#GMainLoop in that thread, to set a new default context for all
async operations in that thread. In this case you may not need to
ever call g_main_context_pop_thread_default(), assuming you want the
new #GMainContext to be the default for the whole lifecycle of the
thread.

If you don&#039;t have control over how the new thread was created (e.g.
in the new thread isn&#039;t newly created, or if the thread life
cycle is managed by a #GThreadPool), it is always suggested to wrap
the logic that needs to use the new #GMainContext inside a
g_main_context_push_thread_default() / g_main_context_pop_thread_default()
pair, otherwise threads that are re-used will end up never explicitly
releasing the #GMainContext reference they hold.

In some cases you may want to schedule a single operation in a
non-default context, or temporarily use a non-default context in
the main thread. In that case, you can wrap the call to the
asynchronous operation inside a
g_main_context_push_thread_default() /
g_main_context_pop_thread_default() pair, but it is up to you to
ensure that no other asynchronous operations accidentally get
started while the non-default context is active.

Beware that libraries that predate this function may not correctly
handle being used from a thread with a thread-default context. Eg,
see g_file_supports_thread_contexts().&lt;/doc&gt;

This API is useful for low-level control over #GMainContext; for
example, integrating it with main loop implementations such as
#GMainLoop.

Another related use for this function is when implementing a main
loop with a termination condition, computed from multiple threads:

|[&amp;lt;!-- language=&quot;C&quot; --&amp;gt;
  #define NUM_TASKS 10
  static gint tasks_remaining = NUM_TASKS;  // (atomic)
  ...
 
  while (g_atomic_int_get (&amp;amp;tasks_remaining) != 0)
    g_main_context_iteration (NULL, TRUE);
]|
 
Then in a thread:
|[&amp;lt;!-- language=&quot;C&quot; --&amp;gt;
  perform_work();

  if (g_atomic_int_dec_and_test (&amp;amp;tasks_remaining))
    g_main_context_wakeup (NULL);
]|&lt;/doc&gt;

of the #GMappedFile. Therefore, mapping should only be used if the file

atomically (e.g. using g_file_set_contents()).

If @writable is %TRUE, the mapped buffer may be modified, otherwise
it is an error to modify the mapped buffer. Modifications to the buffer
are not visible to other processes mapping the same file, and are not

of the #GMappedFile. Therefore, mapping should only be used if the file
will not be modified, or if all modifications of the file are done
atomically (e.g. using g_file_set_contents()).&lt;/doc&gt;

feed a document into the parser incrementally, via multiple calls
to this function. Typically, as you receive data from a network
connection or file, you feed each received chunk of data into this
function, aborting the process if an error occurs. Once an error
is reported, no further data may be fed to the #GMarkupParseContext;
all errors are fatal.&lt;/doc&gt;

This function exists to collect the user_data allocated by a
matching call to g_markup_parse_context_push(). It must be called
in the end_element handler corresponding to the start_element
handler during which g_markup_parse_context_push() was called.
You must not call this function from the error callback -- the
@user_data is provided directly to the callback in that case.

This function is not intended to be directly called by users
interested in invoking subparsers. Instead, it is intended to
be used by the subparsers themselves to implement a higher-level
interface.&lt;/doc&gt;

             line=&quot;1946&quot;&gt;Temporarily redirects markup data to a sub-parser.

This function may only be called from the start_element handler of
a #GMarkupParser. It must be matched with a corresponding call to
g_markup_parse_context_pop() in the matching end_element handler
(except in the case that the parser aborts due to an error).

All tags, text and other data between the matching tags is
redirected to the subparser given by @parser. @user_data is used
as the user_data for that parser. @user_data is also passed to the
error callback in the event that an error occurs. This includes
errors that occur in subparsers of the subparser.

The end tag matching the start tag for which this call was made is
handled by the previous parser (which is given its own user_data)
which is why g_markup_parse_context_pop() is provided to allow &quot;one
last access&quot; to the @user_data provided to this function. In the
case of error, the @user_data provided here is passed directly to
the error callback of the subparser and g_markup_parse_context_pop()
should not be called. In either case, if @user_data was allocated
then it ought to be freed from both of these locations.

This function is not intended to be directly called by users
interested in invoking subparsers. Instead, it is intended to be
used by the subparsers themselves to implement a higher-level
interface.

As an example, see the following implementation of a simple
parser that counts the number of tags encountered.

|[&amp;lt;!-- language=&quot;C&quot; --&amp;gt;
typedef struct
{
  gint tag_count;
} CounterData;

static void
counter_start_element (GMarkupParseContext  *context,
                       const gchar          *element_name,
                       const gchar         **attribute_names,
                       const gchar         **attribute_values,
                       gpointer              user_data,
                       GError              **error)
{
  CounterData *data = user_data;

  data-&amp;gt;tag_count++;
}

static void
counter_error (GMarkupParseContext *context,
               GError              *error,
               gpointer             user_data)
{
  CounterData *data = user_data;

  g_slice_free (CounterData, data);
}

static GMarkupParser counter_subparser =
{
  counter_start_element,
  NULL,
  NULL,
  NULL,
  counter_error
};
]|

In order to allow this parser to be easily used as a subparser, the
following interface is provided:

|[&amp;lt;!-- language=&quot;C&quot; --&amp;gt;
void
start_counting (GMarkupParseContext *context)
{
  CounterData *data = g_slice_new (CounterData);

  data-&amp;gt;tag_count = 0;
  g_markup_parse_context_push (context, &amp;amp;counter_subparser, data);
}

gint
end_counting (GMarkupParseContext *context)
{
  CounterData *data = g_markup_parse_context_pop (context);
  int result;

  result = data-&amp;gt;tag_count;
  g_slice_free (CounterData, data);

  return result;
}
]|

The subparser would then be used as follows:

|[&amp;lt;!-- language=&quot;C&quot; --&amp;gt;
static void start_element (context, element_name, ...)
{
  if (strcmp (element_name, &quot;count-these&quot;) == 0)
    start_counting (context);

  // else, handle other tags...
}

static void end_element (context, element_name, ...)
{
  if (strcmp (element_name, &quot;count-these&quot;) == 0)
    g_print (&quot;Counted %d tags\n&quot;, end_counting (context));

  // else, handle other tags...
}
]|&lt;/doc&gt;

references and escape sequences expanded. References refer to the last
match done with @string against @regex and have the same syntax used by
g_regex_replace().

The @string_to_expand must be UTF-8 encoded even if %G_REGEX_RAW was
passed to g_regex_new().

The backreferences are extracted from the string passed to the match
function, so you cannot call this function after freeing the string.

@match_info may be %NULL in which case @string_to_expand must not
contain references. For instance &quot;foo\n&quot; does not refer to an actual
pattern and &#039;\n&#039; merely will be replaced with \n character,
while to expand &quot;\0&quot; (whole match) one needs the result of a match.
Use g_regex_check_replacement() to find out whether @string_to_expand
contains references.&lt;/doc&gt;

set, 2 the second, and so on.

If @match_num is a valid sub pattern but it didn&#039;t match anything

If the match was obtained using the DFA algorithm, that is using

string is not that of a set of parentheses but that of a matched
substring. Substrings are matched in reverse order of length, so
0 is the longest match.

parentheses. 0 is the full text of the match, 1 is the first
paren set, 2 the second, and so on.

If @match_num is a valid sub pattern but it didn&#039;t match anything
(e.g. sub pattern 1, matching &quot;b&quot; against &quot;(a)?b&quot;) then @start_pos
and @end_pos are set to -1 and %TRUE is returned.

If the match was obtained using the DFA algorithm, that is using
g_regex_match_all() or g_regex_match_all_full(), the retrieved
position is not that of a set of parentheses but that of a matched
substring. Substrings are matched in reverse order of length, so
0 is the longest match.&lt;/doc&gt;

             line=&quot;1279&quot;&gt;Usually if the string passed to g_regex_match*() matches as far as
it goes, but is too short to match the entire pattern, %FALSE is
returned. There are circumstances where it might be helpful to
distinguish this case from other cases in which there is no match.

Consider, for example, an application where a human is required to
type in data for a field with specific formatting requirements. An
example might be a date in the form ddmmmyy, defined by the pattern
&quot;^\d?\d(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\d\d$&quot;.
If the application sees the user’s keystrokes one by one, and can
check that what has been typed so far is potentially valid, it is
able to raise an error as soon as a mistake is made.

GRegex supports the concept of partial matching by means of the
%G_REGEX_MATCH_PARTIAL_SOFT and %G_REGEX_MATCH_PARTIAL_HARD flags.
When they are used, the return code for
g_regex_match() or g_regex_match_full() is, as usual, %TRUE
for a complete match, %FALSE otherwise. But, when these functions
return %FALSE, you can check if the match was partial calling
g_match_info_is_partial_match().

The difference between %G_REGEX_MATCH_PARTIAL_SOFT and
%G_REGEX_MATCH_PARTIAL_HARD is that when a partial match is encountered
with %G_REGEX_MATCH_PARTIAL_SOFT, matching continues to search for a
possible complete match, while with %G_REGEX_MATCH_PARTIAL_HARD matching
stops at the partial match.
When both %G_REGEX_MATCH_PARTIAL_SOFT and %G_REGEX_MATCH_PARTIAL_HARD
are set, the latter takes precedence.

There were formerly some restrictions on the pattern for partial matching.
The restrictions no longer apply.

See pcrepartial(3) for more information on partial matching.&lt;/doc&gt;

           filename=&quot;glib/gthread.c&quot;
           line=&quot;161&quot;&gt;The #GMutex struct is an opaque data structure to represent a mutex
(mutual exclusion). It can be used to protect data against shared
access.

Take for example the following function:
|[&amp;lt;!-- language=&quot;C&quot; --&amp;gt;
  int
  give_me_next_number (void)
  {
    static int current_number = 0;

    // now do a very complicated calculation to calculate the new
    // number, this might for example be a random number generator
    current_number = calc_next_number (current_number);

    return current_number;
  }
]|
It is easy to see that this won&#039;t work in a multi-threaded
application. There current_number must be protected against shared
access. A #GMutex can be used as a solution to this problem:
|[&amp;lt;!-- language=&quot;C&quot; --&amp;gt;
  int
  give_me_next_number (void)
  {
    static GMutex mutex;
    static int current_number = 0;
    int ret_val;

    g_mutex_lock (&amp;amp;mutex);
    ret_val = current_number = calc_next_number (current_number);
    g_mutex_unlock (&amp;amp;mutex);

    return ret_val;
  }
]|
Notice that the #GMutex is not initialised to any particular value.
Its placement in static storage ensures that it will be initialised
to all-zeros, which is appropriate.

If a #GMutex is placed in other contexts (eg: embedded in a struct)
then it must be explicitly initialised using g_mutex_init().

A #GMutex should only be accessed via g_mutex_ functions.&lt;/doc&gt;

This function is useful to initialize a mutex that has been
allocated on the stack, or as part of a larger structure.
It is not necessary to initialize a mutex that has been
statically allocated.

|[&amp;lt;!-- language=&quot;C&quot; --&amp;gt;
  typedef struct {
    GMutex m;
    ...
  } Blob;

Blob *b;

b = g_new (Blob, 1);
g_mutex_init (&amp;amp;b-&amp;gt;m);
]|

To undo the effect of g_mutex_init() when a mutex is no longer
needed, use g_mutex_clear().

Calling g_mutex_init() on an already initialized #GMutex leads
to undefined behaviour.&lt;/doc&gt;

g_once_init_leave() and the unique address @value_location, it can
be ensured that an initialization section will be executed only once
during a program&#039;s life time, and that concurrent threads are
blocked until initialization completed. To be used in constructs
like this:

which have been added to @context. A side-effect of
calling this function is that g_set_prgname() will be
called.

If the parsing is successful, any parsed arguments are
removed from the array and @argc and @argv are updated
accordingly. A &#039;--&#039; option is stripped from @argv
unless there are unparsed options before and after it,
or some of the options after it start with &#039;-&#039;. In case
of an error, @argc and @argv are left unmodified.

If automatic `--help` support is enabled
(see g_option_context_set_help_enabled()), and the
@argv array contains one of the recognized help options,
this function will produce help output to stdout and
call `exit (0)`.

Note that function depends on the [current locale][setlocale] for
automatic character set conversion of string and filename
arguments.&lt;/doc&gt;

This function is similar to g_option_context_parse() except that it
respects the normal memory rules when dealing with a strv instead of
assuming that the passed-in array is the argv of the main function.

In particular, strings that are removed from the arguments list will
be freed using g_free().

On Windows, the strings are expected to be in UTF-8.  This is in
contrast to g_option_context_parse() which expects them to be in the
system codepage, which is how they are passed as @argv to main().
See g_win32_get_command_line() for a solution.

This function is useful if you are trying to use #GOptionContext with
#GApplication.&lt;/doc&gt;

             line=&quot;342&quot;&gt;Sets strict POSIX mode.

By default, this mode is disabled.

In strict POSIX mode, the first non-argument parameter encountered
(eg: filename) terminates argument processing.  Remaining arguments
are treated as non-options and are not attempted to be parsed.

If strict POSIX mode is disabled then parsing is done in the GNU way
where option arguments can be freely mixed with non-options.

As an example, consider &quot;ls foo -l&quot;.  With GNU style parsing, this
will list &quot;foo&quot; in long mode.  In strict POSIX style, this will list
the files named &quot;foo&quot; and &quot;-l&quot;.

It may be useful to force strict POSIX mode when creating &quot;verb
style&quot; command line tools.  For example, the &quot;gsettings&quot; command line
tool supports the global option &quot;--schemadir&quot; as well as many
subcommands (&quot;get&quot;, &quot;set&quot;, etc.) which each have their own set of
arguments.  Using strict POSIX mode will allow parsing the global
options up to the verb name while leaving the remaining options to be
parsed by the relevant subcommand (which can be determined by
examining the verb name, which should be present in argv[1] after
parsing).&lt;/doc&gt;

The @parameter_string can serve multiple purposes. It can be used
to add descriptions for &quot;rest&quot; arguments, which are not parsed by
the #GOptionContext, typically something like &quot;FILES&quot; or
&quot;FILE1 FILE2...&quot;. If you are using %G_OPTION_REMAINING for
collecting &quot;rest&quot; arguments, GLib handles this automatically by
using the @arg_description of the corresponding #GOptionEntry in
the usage summary.

Another usage is to give a short summary of the program
functionality, like &quot; - frob the strings&quot;, which will be displayed
in the same line as the usage. For a longer description of the
program functionality that should be displayed as a paragraph
below the usage line, use g_option_context_set_summary().

Note that the @parameter_string is translated using the
function set with g_option_context_set_translate_func(), so
it should normally be passed untranslated.&lt;/doc&gt;

           line=&quot;969&quot;&gt;A macro to assist with the static initialisation of a #GPrivate.

This macro is useful for the case that a #GDestroyNotify function
should be associated with the key.  This is needed when the key will be
used to point at memory that should be deallocated when the thread
exits.

Additionally, the #GDestroyNotify will also be called on the previous
value stored in the key when g_private_replace() is used.

If no #GDestroyNotify is needed, then use of this macro is not
required -- if the #GPrivate is declared in static scope then it will
be properly initialised by default (ie: to all zeros).  See the
examples below.

individual elements, using the platform specific conventions for path

g_path_buf_push (&amp;amp;path, &quot;usr&quot;);

If the path buffer contains a path, this is the equivalent of
popping the path buffer and pushing @file_name, creating a
sibling of the original path.

           line=&quot;33&quot;&gt;A `GPatternSpec` struct is the &#039;compiled&#039; form of a glob-style pattern.

The [func@GLib.pattern_match_simple] and [method@GLib.PatternSpec.match] functions
match a string against a pattern containing &#039;*&#039; and &#039;?&#039; wildcards with similar
semantics as the standard `glob()` function: &#039;*&#039; matches an arbitrary,
possibly empty, string, &#039;?&#039; matches an arbitrary character.

Note that in contrast to `glob()`, the &#039;/&#039; character can be matched by
the wildcards, there are no &#039;[...]&#039; character ranges and &#039;*&#039; and &#039;?&#039;
can not be escaped to include them literally in a pattern.

When multiple strings must be matched against the same pattern, it is better
to compile the pattern to a [struct@GLib.PatternSpec] using
[ctor@GLib.PatternSpec.new] and use [method@GLib.PatternSpec.match_string]
instead of [func@GLib.pattern_match_simple]. This avoids the overhead of repeated
pattern compilation.&lt;/doc&gt;

length of the string given is mandatory. The reversed string can be
omitted by passing %NULL, this is more efficient if the reversed
version of the string to be matched is not at hand, as
g_pattern_match() will only construct it if the compiled pattern
requires reverse matches.

Note that, if the user code will (possibly) match a string against a
multitude of patterns containing wildcards, chances are high that
some patterns will require a reversed string. In this case, it&#039;s
more efficient to provide the reversed string to avoid multiple
constructions thereof in the various calls to g_pattern_match().

Note also that the reverse of a UTF-8 encoded string can in general
not be obtained by g_strreverse(). This works only if the string
does not contain any multibyte characters. GLib offers the
g_utf8_strreverse() function to reverse UTF-8 encoded strings.&lt;/doc&gt;

thread-local data key. It is approximately equivalent to the
pthread_setspecific()/pthread_getspecific() APIs on POSIX and to
TlsSetValue()/TlsGetValue() on Windows.

If you don&#039;t already know why you might want this functionality,
then you probably don&#039;t need it.

#GPrivate is a very limited resource (as far as 128 per program,
shared between all libraries). It is also not possible to destroy a
#GPrivate after it has been used. As such, it is only ever acceptable
to use #GPrivate in static scope, and even then sparingly so.

See G_PRIVATE_INIT() for a couple of examples.

The #GPrivate structure should be considered opaque.  It should only
be accessed via the g_private_ functions.&lt;/doc&gt;

@func, as a #GCopyFunc, takes two arguments, the data to be copied
and a @user_data pointer. On common processor architectures, it&#039;s safe to
pass %NULL as @user_data if the copy function takes only one argument. You
may get compiler warnings from this though if compiling with GCC’s
`-Wcast-function-type` warning.

If @func is %NULL, then only the pointers (and not what they are
pointing to) are copied to the new #GPtrArray.

The copy of @array will have the same #GDestroyNotify for its elements as
@array. The copy will also be %NULL terminated if (and only if) the source
array is.&lt;/doc&gt;

@func, as a #GCopyFunc, takes two arguments, the data to be copied

pass %NULL as @user_data if the copy function takes only one argument. You
may get compiler warnings from this though if compiling with GCC’s
`-Wcast-function-type` warning.

If @func is %NULL, then only the pointers (and not what they are
pointing to) are copied to the new #GPtrArray.

Whether @array_to_extend is %NULL terminated stays unchanged by this function.&lt;/doc&gt;

it frees the memory block holding the elements as well. Pass %FALSE
if you want to free the #GPtrArray wrapper but preserve the
underlying array for use elsewhere. If the reference count of @array
is greater than one, the #GPtrArray wrapper is preserved but the
size of @array will be set to zero.

If array contents point to dynamically-allocated memory, they should
be freed separately if @free_seg is %TRUE and no #GDestroyNotify
function has been set for @array.

Note that if the array is %NULL terminated and @free_seg is %FALSE
then this will always return an allocated %NULL terminated buffer.
If pdata is previously %NULL, a new buffer will be allocated.

This function is not thread-safe. If using a #GPtrArray from multiple

additional %NULL pointer after the last element, beyond the

#GPtrArray created by other constructors are not automatically %NULL
terminated.

Note that if the @array&#039;s length is zero and currently no
data array is allocated, then pdata will still be %NULL.
%GPtrArray will only %NULL terminate pdata, if an actual
array is allocated. It does not guarantee that an array
is always allocated. In other words, if the length is zero,
then pdata may either point to a %NULL terminated array of length
zero or be %NULL.&lt;/doc&gt;

the pointers in the array.

Use g_ptr_array_sort_values() if you want to use normal
#GCompareFuncs, otherwise here is a full example of use:

|[&amp;lt;!-- language=&quot;C&quot; --&amp;gt;
typedef struct
{
  gchar *name;
  gint size;
} FileListEntry;

static gint
sort_filelist (gconstpointer a, gconstpointer b)
{
  const FileListEntry *entry1 = *((FileListEntry **) a);
  const FileListEntry *entry2 = *((FileListEntry **) b);

  return g_ascii_strcasecmp (entry1-&amp;gt;name, entry2-&amp;gt;name);
}

…
g_autoptr (GPtrArray) file_list = NULL;

// initialize file_list array and load with many FileListEntry entries
...
// now sort it with
g_ptr_array_sort (file_list, sort_filelist);

This is guaranteed to be a stable sort since version 2.32.&lt;/doc&gt;

Note that this should be used in a place where it is allowed to declare a
variable, which could be before any statement in the case
`-Wdeclaration-after-statement` is used, or C standard prior to C99.

           filename=&quot;glib/gthread.c&quot;
           line=&quot;233&quot;&gt;The GRWLock struct is an opaque data structure to represent a
reader-writer lock. It is similar to a #GMutex in that it allows
multiple threads to coordinate access to a shared resource.

The difference to a mutex is that a reader-writer lock discriminates
between read-only (&#039;reader&#039;) and full (&#039;writer&#039;) access. While only
one thread at a time is allowed write access (by holding the &#039;writer&#039;
lock via g_rw_lock_writer_lock()), multiple threads can gain
simultaneous read-only access (by holding the &#039;reader&#039; lock via
g_rw_lock_reader_lock()).

It is unspecified whether readers or writers have priority in acquiring the
lock when a reader already holds the lock and a writer is queued to acquire
it.

Here is an example for an array with access functions:
|[&amp;lt;!-- language=&quot;C&quot; --&amp;gt;
  GRWLock lock;
  GPtrArray *array;

  gpointer
  my_array_get (guint index)
  {
    gpointer retval = NULL;

    if (!array)
      return NULL;

    g_rw_lock_reader_lock (&amp;amp;lock);
    if (index &amp;lt; array-&amp;gt;len)
      retval = g_ptr_array_index (array, index);
    g_rw_lock_reader_unlock (&amp;amp;lock);

    return retval;
  }

  void
  my_array_set (guint index, gpointer data)
  {
    g_rw_lock_writer_lock (&amp;amp;lock);

    if (!array)
      array = g_ptr_array_new ();

    if (index &amp;gt;= array-&amp;gt;len)
      g_ptr_array_set_size (array, index+1);
    g_ptr_array_index (array, index) = data;

    g_rw_lock_writer_unlock (&amp;amp;lock);
  }
 ]|
This example shows an array which can be accessed by many readers
(the my_array_get() function) simultaneously, whereas the writers
(the my_array_set() function) will only be allowed one at a time
and only if no readers currently access the array. This is because
of the potentially dangerous resizing of the array. Using these
functions is fully multi-thread safe now.

If a #GRWLock is allocated in static storage then it can be used
without initialisation.  Otherwise, you should call
g_rw_lock_init() on it and g_rw_lock_clear() when done.

A GRWLock should only be accessed with the g_rw_lock_ functions.&lt;/doc&gt;

             line=&quot;518&quot;&gt;Frees the resources allocated to a lock with g_rw_lock_init().

This function should not be used with a #GRWLock that has been

This function is useful to initialize a lock that has been
allocated on the stack, or as part of a larger structure.  It is not
necessary to initialise a reader-writer lock that has been statically
allocated.

|[&amp;lt;!-- language=&quot;C&quot; --&amp;gt;
  typedef struct {
    GRWLock l;
    ...
  } Blob;

Blob *b;

b = g_new (Blob, 1);
g_rw_lock_init (&amp;amp;b-&amp;gt;l);
]|

To undo the effect of g_rw_lock_init() when a lock is no longer
needed, use g_rw_lock_clear().

Calling g_rw_lock_init() on an already initialized #GRWLock leads
to undefined behaviour.&lt;/doc&gt;

the write lock on @rw_lock, the current thread will block until the
write lock was (held and) released. If another thread does not hold
the write lock, but is waiting for it, it is implementation defined
whether the reader or writer will block. Read locks can be taken
recursively.

Calling g_rw_lock_reader_lock() while the current thread already
owns a write lock leads to undefined behaviour. Read locks however
can be taken recursively, in which case you need to make sure to
call g_rw_lock_reader_unlock() the same amount of times.

It is implementation-defined how many read locks are allowed to be
held on the same lock simultaneously. If the limit is hit,
or if a deadlock is detected, a critical warning will be emitted.&lt;/doc&gt;

recursive mutex. It is similar to a #GMutex with the difference
that it is possible to lock a GRecMutex multiple times in the same
thread without deadlock. When doing so, care has to be taken to
unlock the recursive mutex as often as it has been locked.

If a #GRecMutex is allocated in static storage then it can be used
without initialisation.  Otherwise, you should call
g_rec_mutex_init() on it and g_rec_mutex_clear() when done.

A GRecMutex should only be accessed with the
g_rec_mutex_ functions.&lt;/doc&gt;

Calling g_rec_mutex_init() on an already initialized #GRecMutex
leads to undefined behaviour.

To undo the effect of g_rec_mutex_init() when a recursive mutex
is no longer needed, use g_rec_mutex_clear().&lt;/doc&gt;

           line=&quot;42&quot;&gt;A `GRegex` is the &quot;compiled&quot; form of a regular expression pattern.

`GRegex` implements regular expression pattern matching using syntax and
semantics similar to Perl regular expression. See the
[PCRE documentation](man:pcrepattern(3)) for the syntax definition.

Some functions accept a @start_position argument, setting it differs
from just passing over a shortened string and setting %G_REGEX_MATCH_NOTBOL
in the case of a pattern that begins with any kind of lookbehind assertion.
For example, consider the pattern &quot;\Biss\B&quot; which finds occurrences of &quot;iss&quot;
in the middle of words. (&quot;\B&quot; matches only if the current position in the
subject is not a word boundary.) When applied to the string &quot;Mississipi&quot;
from the fourth byte, namely &quot;issipi&quot;, it does not match, because &quot;\B&quot; is
always false at the start of the subject, which is deemed to be a word
boundary. However, if the entire string is passed , but with
@start_position set to 4, it finds the second occurrence of &quot;iss&quot; because
it is able to look behind the starting point to discover that it is
preceded by a letter.

Note that, unless you set the %G_REGEX_RAW flag, all the strings passed
to these functions must be encoded in UTF-8. The lengths and the positions
inside the strings are in bytes and not in characters, so, for instance,
&quot;\xc3\xa0&quot; (i.e. &quot;à&quot;) is two bytes long but it is treated as a
single character. If you set %G_REGEX_RAW the strings can be non-valid
UTF-8 strings and a byte is treated as a character, so &quot;\xc3\xa0&quot; is two
bytes and two characters long.

When matching a pattern, &quot;\n&quot; matches only against a &quot;\n&quot; character in
the string, and &quot;\r&quot; matches only a &quot;\r&quot; character. To match any newline
sequence use &quot;\R&quot;. This particular group matches either the two-character
sequence CR + LF (&quot;\r\n&quot;), or one of the single characters LF (linefeed,
U+000A, &quot;\n&quot;), VT vertical tab, U+000B, &quot;\v&quot;), FF (formfeed, U+000C, &quot;\f&quot;),
CR (carriage return, U+000D, &quot;\r&quot;), NEL (next line, U+0085), LS (line
separator, U+2028), or PS (paragraph separator, U+2029).

The behaviour of the dot, circumflex, and dollar metacharacters are
affected by newline characters, the default is to recognize any newline
character (the same characters recognized by &quot;\R&quot;). This can be changed
with `G_REGEX_NEWLINE_CR`, `G_REGEX_NEWLINE_LF` and `G_REGEX_NEWLINE_CRLF`
compile options, and with `G_REGEX_MATCH_NEWLINE_ANY`,
`G_REGEX_MATCH_NEWLINE_CR`, `G_REGEX_MATCH_NEWLINE_LF` and
`G_REGEX_MATCH_NEWLINE_CRLF` match options. These settings are also
relevant when compiling a pattern if `G_REGEX_EXTENDED` is set, and an
unescaped &quot;#&quot; outside a character class is encountered. This indicates
a comment that lasts until after the next newline.

Creating and manipulating the same `GRegex` structure from different
threads is not a problem as `GRegex` does not modify its internal
state between creation and destruction, on the other hand `GMatchInfo`
is not threadsafe.

The regular expressions low-level functionalities are obtained through
the excellent [PCRE](http://www.pcre.org/) library written by Philip Hazel.&lt;/doc&gt;

The @match_options are combined with the match options specified
when the @regex structure was created, letting you have more
flexibility in reusing #GRegex structures.

Unless %G_REGEX_RAW is specified in the options, @string must be valid UTF-8.

A #GMatchInfo structure, used to get information on the match,
is stored in @match_info if not %NULL. Note that if @match_info
is not %NULL then it is created even if the function returns %FALSE,
i.e. you must free it regardless if regular expression actually matched.

To retrieve all the non-overlapping matches of the pattern in
string you can use g_match_info_next().

             line=&quot;2340&quot;&gt;Using the standard algorithm for regular expression matching only
the longest match in the @string is retrieved, it is not possible
to obtain all the available matches. For instance matching
&quot;&amp;lt;a&amp;gt; &amp;lt;b&amp;gt; &amp;lt;c&amp;gt;&quot; against the pattern &quot;&amp;lt;.*&amp;gt;&quot;
you get &quot;&amp;lt;a&amp;gt; &amp;lt;b&amp;gt; &amp;lt;c&amp;gt;&quot;.

This function uses a different algorithm (called DFA, i.e. deterministic
finite automaton), so it can retrieve all the possible matches, all
starting at the same point in the string. For instance matching
&quot;&amp;lt;a&amp;gt; &amp;lt;b&amp;gt; &amp;lt;c&amp;gt;&quot; against the pattern &quot;&amp;lt;.*&amp;gt;;&quot;
you would obtain three matches: &quot;&amp;lt;a&amp;gt; &amp;lt;b&amp;gt; &amp;lt;c&amp;gt;&quot;,
&quot;&amp;lt;a&amp;gt; &amp;lt;b&amp;gt;&quot; and &quot;&amp;lt;a&amp;gt;&quot;.

The number of matched strings is retrieved using
g_match_info_get_match_count(). To obtain the matched strings and
their position you can use, respectively, g_match_info_fetch() and
g_match_info_fetch_pos(). Note that the strings are returned in
reverse order of length; that is, the longest matching string is
given first.

Note that the DFA algorithm is slower than the standard one and it
is not able to capture substrings, so backreferences do not work.

Setting @start_position differs from just passing over a shortened
string and setting %G_REGEX_MATCH_NOTBOL in the case of a pattern
that begins with any kind of lookbehind assertion, such as &quot;\b&quot;.

Unless %G_REGEX_RAW is specified in the options, @string must be valid UTF-8.

A #GMatchInfo structure, used to get information on the match, is
stored in @match_info if not %NULL. Note that if @match_info is
not %NULL then it is created even if the function returns %FALSE,
i.e. you must free it regardless if regular expression actually
matched.

you use any #GMatchInfo method (except g_match_info_free()) after

             line=&quot;2207&quot;&gt;Scans for a match in @string for the pattern in @regex.
The @match_options are combined with the match options specified
when the @regex structure was created, letting you have more
flexibility in reusing #GRegex structures.

Setting @start_position differs from just passing over a shortened
string and setting %G_REGEX_MATCH_NOTBOL in the case of a pattern
that begins with any kind of lookbehind assertion, such as &quot;\b&quot;.

Unless %G_REGEX_RAW is specified in the options, @string must be valid UTF-8.

A #GMatchInfo structure, used to get information on the match, is
stored in @match_info if not %NULL. Note that if @match_info is
not %NULL then it is created even if the function returns %FALSE,
i.e. you must free it regardless if regular expression actually
matched.

@string is not copied and is used in #GMatchInfo internally. If
you use any #GMatchInfo method (except g_match_info_free()) after
freeing or modifying @string then the behaviour is undefined.

To retrieve all the non-overlapping matches of the pattern in
string you can use g_match_info_next().

number-th captured subexpression of the match, &#039;\g&amp;lt;name&amp;gt;&#039; refers
to the captured subexpression with the given name. &#039;\0&#039; refers
to the complete match, but &#039;\0&#039; followed by a number is the octal
representation of a character. To include a literal &#039;\&#039; in the
replacement, write &#039;\\\\&#039;.

There are also escapes that changes the case of the following text:

- \l: Convert to lower case the next character
- \u: Convert to upper case the next character
- \L: Convert to lower case till \E
- \U: Convert to upper case till \E
- \E: End case modification

If you do not need to use backreferences use g_regex_replace_literal().

The @replacement string must be UTF-8 encoded even if %G_REGEX_RAW was
passed to g_regex_new(). If you want to use not UTF-8 encoded strings
you can use g_regex_replace_literal().

If the pattern contains capturing parentheses, then the text for each

anywhere in the string, then the whole string is returned as the first

As a special case, the result of splitting the empty string &quot;&quot; is an
empty vector, not a vector containing a single string. The reason for
this special case is that being able to represent an empty vector is
typically more useful than consistent handling of empty elements. If
you do need to represent empty elements, you&#039;ll need to check for the
empty string before calling this function.

A pattern that can match empty strings splits @string into separate
characters wherever it matches the empty string between characters.
For example splitting &quot;ab c&quot; using as a separator &quot;\s*&quot;, you will get
&quot;a&quot;, &quot;b&quot; and &quot;c&quot;.&lt;/doc&gt;

the tokens. If the pattern contains capturing parentheses,
then the text for each of the substrings will also be returned.
If the pattern does not match anywhere in the string, then the
whole string is returned as the first token.

This function is equivalent to g_regex_split() but it does
not require to compile the pattern with g_regex_new(), avoiding
some lines of code when you need just to do a split without
extracting substrings, capture counts, and so on.

If this function is to be called on the same @pattern more than
once, it&#039;s more efficient to compile the pattern once with
g_regex_new() and then use g_regex_split().

As a special case, the result of splitting the empty string &quot;&quot;
is an empty vector, not a vector containing a single string.
The reason for this special case is that being able to represent
an empty vector is typically more useful than consistent handling
of empty elements. If you do need to represent empty elements,
you&#039;ll need to check for the empty string before calling this
function.

A pattern that can match empty strings splits @string into
separate characters wherever it matches the empty string between
characters. For example splitting &quot;ab c&quot; using as a separator
&quot;\s*&quot;, you will get &quot;a&quot;, &quot;b&quot; and &quot;c&quot;.&lt;/doc&gt;

           line=&quot;50&quot;&gt;A `GRelation` is a table of data which can be indexed on any number
of fields, rather like simple database tables. A `GRelation` contains
a number of records, called tuples. Each record contains a number of
fields. Records are not ordered, so it is not possible to find the
record at a particular index.

Note that `GRelation` tables are currently limited to 2 fields.

To create a `GRelation`, use [func@GLib.Relation.new].

To specify which fields should be indexed, use [method@GLib.Relation.index].
Note that this must be called before any tuples are added to the
`GRelation`.

To add records to a `GRelation` use [method@GLib.Relation.insert].

To determine if a given record appears in a `GRelation`, use
[method@GLib.Relation.exists]. Note that fields are compared directly, so
pointers must point to the exact same position (i.e. different
copies of the same string will not match.)

To count the number of records which have a particular value in a
given field, use [method@GLib.Relation.count].

To get all the records which have a particular value in a given
field, use [method@GLib.Relation.select]. To access fields of the resulting
records, use [method@GLib.Tuples.index]. To free the resulting records use
[method@GLib.Tuples.destroy].

To delete all records which have a particular value in a given
field, use [method@GLib.Relation.delete].

To destroy the `GRelation`, use [method@GLib.Relation.destroy].

To help debug `GRelation` objects, use [method@GLib.Relation.print].

`GRelation` has been marked as deprecated, since this API has never
been fully implemented, is not very actively maintained and rarely

The return value is the new start of the list, which may
have changed, so make sure you store the new value.

Note that g_slist_append() has to traverse the entire list
to find the end, which is inefficient when adding multiple
elements. A common idiom to avoid the inefficiency is to prepend
the elements and reverse the list when all elements have been added.

In contrast with g_slist_copy(), this function uses @func to make a copy of
each list element, in addition to copying the list container itself.

@func, as a #GCopyFunc, takes two arguments, the data to be copied
and a @user_data pointer. On common processor architectures, it&#039;s safe to
pass %NULL as @user_data if the copy function takes only one argument. You
may get compiler warnings from this though if compiling with GCC’s
`-Wcast-function-type` warning.

For instance, if @list holds a list of GObjects, you can do:
|[&amp;lt;!-- language=&quot;C&quot; --&amp;gt;
another_list = g_slist_copy_deep (list, (GCopyFunc) g_object_ref, NULL);
]|

And, to entirely free the new list, you could do:
|[&amp;lt;!-- language=&quot;C&quot; --&amp;gt;
g_slist_free_full (another_list, g_object_unref);
]|&lt;/doc&gt;

Removing arbitrary nodes from a singly-linked list requires time

find yourself using g_slist_delete_link() frequently, you should
consider a different data structure, such as the doubly-linked

it is used by the default message handler when displaying
warnings and errors. If you are scanning a file, the filename
would be a good choice.

can place them here.

If you want to use your own message handler you can set the
@msg_handler field. The type of the message handler function

The token data is placed in the @next_token, @next_value, @next_line,

Note that, while the token is not removed from the input stream
(i.e. the next call to g_scanner_get_next_token() will return the
same token), it will not be reevaluated. This can lead to surprising
results when changing scope or the scanner configuration after peeking
the next token. Getting the next token after switching the scope or
configuration will return whatever was peeked before, regardless of
any symbols that may have been added or removed in the new scope.&lt;/doc&gt;

@cmp_func is called with two items of the @seq, and @cmp_data.
It should return 0 if the items are equal, a negative value
if the first item comes before the second, and a positive value
if the second item comes before the first.

Note that when adding a large amount of data to a #GSequence,
it is more efficient to do unsorted insertions and then call

@iter_cmp is called with two iterators pointing into @seq.
It should return 0 if the iterators are equal, a negative
value if the first iterator comes before the second, and a
positive value if the second iterator comes before the first.

Note that when adding a large amount of data to a #GSequence,
it is more efficient to do unsorted insertions and then call
g_sequence_sort() or g_sequence_sort_iter().&lt;/doc&gt;

@iter_cmp is called with two iterators pointing into @seq.
It should return 0 if the iterators are equal, a negative value
if the first iterator comes before the second, and a positive
value if the second iterator comes before the first.

If you are simply searching for an existing element of the sequence,
consider using g_sequence_lookup_iter().

This function will fail if the data contained in the sequence is
unsorted.&lt;/doc&gt;

added to a #GMainContext, @child_source will be automatically added
with the same priority, when @child_source is triggered, it will
cause @source to dispatch (in addition to calling its own
callback), and when @source is destroyed, it will destroy
@child_source as well. (@source will also still be dispatched if
its own prepare/check functions indicate that it is ready.)

If you don&#039;t need @child_source to do anything on its own when it
triggers, you can call g_source_set_dummy_callback() on it to set a
callback that does nothing (except return %TRUE if appropriate).

@source will hold a reference on @child_source while @child_source
is attached to it.

monitoring of the fd using g_source_remove_unix_fd() or
g_source_modify_unix_fd().

It is not necessary to remove the fd before destroying the source; it
will be cleaned up automatically.

This is important when you operate upon your objects
from within idle handlers, but may have freed the object
before the dispatch of your idle handler.

  g_mutex_lock (&amp;amp;self-&amp;gt;idle_id_mutex);
  // do stuff with self
  self-&amp;gt;idle_id = 0;
  g_mutex_unlock (&amp;amp;self-&amp;gt;idle_id_mutex);
   
  return G_SOURCE_REMOVE;
}
 
static void
some_widget_do_stuff_later (SomeWidget *self)
{
  g_mutex_lock (&amp;amp;self-&amp;gt;idle_id_mutex);
  self-&amp;gt;idle_id = g_idle_add (idle_callback, self);
  g_mutex_unlock (&amp;amp;self-&amp;gt;idle_id_mutex);
}
 
static void

{
  g_mutex_init (&amp;amp;self-&amp;gt;idle_id_mutex);

  // ...
}

{
  SomeWidget *self = SOME_WIDGET (object);
   
  if (self-&amp;gt;idle_id)
    g_source_remove (self-&amp;gt;idle_id);
   
  g_mutex_clear (&amp;amp;self-&amp;gt;idle_id_mutex);

  G_OBJECT_CLASS (parent_class)-&amp;gt;finalize (object);
}
]|

This will fail in a multi-threaded application if the
widget is destroyed before the idle handler fires due
to the use after free in the callback. A solution, to
this particular problem, is to check to if the source
has already been destroy within the callback.

|[&amp;lt;!-- language=&quot;C&quot; --&amp;gt;
static gboolean
idle_callback (gpointer data)

  SomeWidget *self = data;

    {
      // do stuff with self
    }
  g_mutex_unlock (&amp;amp;self-&amp;gt;idle_id_mutex);
  
  return FALSE;
}

Calls to this function from a thread other than the one acquired by the
#GMainContext the #GSource is attached to are typically redundant, as the
source could be destroyed immediately after this function returns. However,
once a source is destroyed it cannot be un-destroyed, so this function can be
used for opportunistic checks from any thread.&lt;/doc&gt;

             line=&quot;1702&quot;&gt;Sets the callback function for a source. The callback for a source is
called from the source&#039;s dispatch function.

The exact type of @func depends on the type of source; ie. you
should not count on @func being called with @data as its first
parameter. Cast @func with G_SOURCE_FUNC() to avoid warnings about
incompatible function types.

See [memory management of sources][mainloop-memory-management] for details
on how to handle memory management of @data.

Typically, you won&#039;t use this function. Instead use functions specific
to the type of source you are using, such as g_idle_add() or g_timeout_add().

It is safe to call this function multiple times on a source which has already
been attached to a context. The changes will take effect for the next time
the source is dispatched after this call returns.

Note that g_source_destroy() for a currently attached source has the effect
of also unsetting the callback.&lt;/doc&gt;

allow for the reference count to increase again until @dispose returns.

The dispose function can be used to clear any &quot;weak&quot; references to the
@source in other data structures in a thread-safe way where it is possible
for another thread to increase the reference count of @source again while
it is being freed.

The finalize function can not be used for this purpose as at that point
@source is already partially freed and not valid anymore.

             line=&quot;2056&quot;&gt;Sets a name for the source, used in debugging and profiling.
The name defaults to #NULL.

The source name should describe in a human-readable way
what the source does. For example, &quot;X11 event queue&quot;
or &quot;GTK repaint idle handler&quot; or whatever it is.

It is permitted to call this function multiple times, but is not
recommended due to the potential performance impact.  For example,
one could change the name in the &quot;check&quot; function of a #GSourceFuncs
to include details like the event type in the source name.

Use caution if changing the name while another thread may be
accessing it with g_source_get_name(); that function does not copy
the value, and changing the value will free it while the other thread
may be attempting to use it.

Also see g_source_set_static_name().&lt;/doc&gt;

reached (or passed).  If the monotonic time is in the past (as it
always will be if @ready_time is 0) then the source will be
dispatched immediately.

If @ready_time is -1 then the source is never woken up on the basis
of the passage of time.

Dispatching the source does not reset the ready time.  You should do
so yourself, from the source dispatch function.

Note that if you have a pair of sources where the ready time of one
suggests that it will be delivered first but the priority for the
other suggests that it would be delivered first, and the ready time
for both sources is reached during the same main context iteration,
then the order of dispatch is undefined.

It is a no-op to call this function on a #GSource which has already been
destroyed with g_source_destroy().

This API is only intended to be used by implementations of #GSource.
Do not call this API on a #GSource that you did not create.&lt;/doc&gt;

scheduling an idle to run in another thread with g_idle_add(): the
idle may already have run and been removed by the time this function
is called on its (now invalid) source ID.  This source ID may have
been reissued, leading to the operation being performed against the

           line=&quot;101&quot;&gt;The `GSourceFuncs` struct contains a table of
functions used to handle event sources in a generic manner.

For idle sources, the prepare and check functions always return %TRUE
to indicate that the source is always ready to be processed. The prepare
function also returns a timeout value of 0 to ensure that the poll() call
doesn&#039;t block (since that would be time wasted which could have been spent
running the idle function).

For timeout sources, the prepare and check functions both return %TRUE
if the timeout interval has expired. The prepare function also returns
a timeout value to ensure that the poll() call doesn&#039;t block too long
and miss the next timeout.

For file descriptor sources, the prepare function typically returns %FALSE,
since it must wait until poll() has been called before it knows whether
any events need to be processed. It sets the returned timeout to -1 to
indicate that it doesn&#039;t mind how long the poll() call blocks. In the
check function, it tests the results of the poll() call to see if the
required condition has been met, and returns %TRUE if so.&lt;/doc&gt;

    source can determine that it is ready here (without waiting for the
    results of the poll() call) it should return %TRUE. It can also return
    a @timeout_ value which should be the maximum timeout (in milliseconds)
    which should be passed to the poll() call. The actual timeout used will
    be -1 if all sources returned -1, or it will be the minimum of all
    the @timeout_ values returned which were &amp;gt;= 0.  Since 2.36 this may
    be %NULL, in which case the effect is as if the function always returns
    %FALSE with a timeout of -1.  If @prepare returns a
    timeout and the source also has a ready time set, then the
    lower of the two will be used.&lt;/doc&gt;

           line=&quot;105&quot;&gt;Specifies the type of the setup function passed to g_spawn_async(),
g_spawn_sync() and g_spawn_async_with_pipes(), which can, in very
limited ways, be used to affect the child&#039;s execution.

On POSIX platforms, the function is called in the child after GLib
has performed all the setup it plans to perform, but before calling
exec(). Actions taken in this function will only affect the child,
not the parent.

On Windows, the function is called in the parent. Its usefulness on
Windows is thus questionable. In many cases executing the child setup
function in the parent can have ill effects, and you should be very
careful when porting software to Windows that uses child setup
functions.

However, even on POSIX, you are extremely limited in what you can
safely do from a #GSpawnChildSetupFunc, because any mutexes that were
held by other threads in the parent process at the time of the fork()
will still be locked in the child process, and they will never be
unlocked (since the threads that held them don&#039;t exist in the child).
POSIX allows only async-signal-safe functions (see signal(7)) to be
called in the child between fork() and exec(), which drastically limits
the usefulness of child setup functions.

In particular, it is not safe to call any function which may
call malloc(), which includes POSIX functions such as setenv().
If you need to set up the child environment differently from
the parent, you should use g_get_environ(), g_environ_setenv(),
and g_environ_unsetenv(), and then pass the complete environment
list to the `g_spawn...` function.&lt;/doc&gt;

           line=&quot;392&quot;&gt;A #GStaticMutex works like a #GMutex.

Prior to GLib 2.32, GStaticMutex had the significant advantage
that it doesn&#039;t need to be created at run-time, but can be defined
at compile-time. Since 2.32, #GMutex can be statically allocated
as well, and GStaticMutex has been deprecated.

Here is a version of our give_me_next_number() example using
a GStaticMutex:
|[
  int
  give_me_next_number (void)
  {
    static int current_number = 0;
    int ret_val;
    static GStaticMutex mutex = G_STATIC_MUTEX_INIT;

    g_static_mutex_lock (&amp;amp;mutex);
    ret_val = current_number = calc_next_number (current_number);
    g_static_mutex_unlock (&amp;amp;mutex);

    return ret_val;
  }
]|

Sometimes you would like to dynamically create a mutex. If you don&#039;t
want to require prior calling to g_thread_init(), because your code
should also be usable in non-threaded programs, you are not able to
use g_mutex_new() and thus #GMutex, as that requires a prior call to
g_thread_init(). In these cases you can also use a #GStaticMutex.
It must be initialized with g_static_mutex_init() before using it
and freed with with g_static_mutex_free() when not needed anymore to
free up any allocated resources.

Even though #GStaticMutex is not opaque, it should only be used with
the following functions, as it is defined differently on different
platforms.

All of the g_static_mutex_* functions apart from
g_static_mutex_get_mutex() can also be used even if g_thread_init()
has not yet been called. Then they do nothing, apart from
g_static_mutex_trylock() which does nothing but returning %TRUE.

All of the g_static_mutex_* functions are actually macros. Apart from
taking their addresses, you can however use them as if they were
functions.&lt;/doc&gt;

      &lt;/field&gt;

You don&#039;t have to call this functions for a #GStaticMutex with an
unbounded lifetime, i.e. objects declared &#039;static&#039;, but if you have
a #GStaticMutex as a member of a structure and the structure is
freed, you should also free the #GStaticMutex.

Calling g_static_mutex_free() on a locked mutex may result in
undefined behaviour.&lt;/doc&gt;

@notify is used quite differently from @destructor in g_private_new().&lt;/doc&gt;

           line=&quot;849&quot;&gt;The #GStaticRWLock struct represents a read-write lock. A read-write
lock can be used for protecting data that some portions of code only
read from, while others also write. In such situations it is
desirable that several readers can read at once, whereas of course
only one writer may write at a time.

Take a look at the following example:
|[
  GStaticRWLock rwlock = G_STATIC_RW_LOCK_INIT;
  GPtrArray *array;

  gpointer
  my_array_get (guint index)
  {
    gpointer retval = NULL;

    if (!array)
      return NULL;

    g_static_rw_lock_reader_lock (&amp;amp;rwlock);
    if (index &amp;lt; array-&amp;gt;len)
      retval = g_ptr_array_index (array, index);
    g_static_rw_lock_reader_unlock (&amp;amp;rwlock);

    return retval;
  }

  void
  my_array_set (guint index, gpointer data)
  {
    g_static_rw_lock_writer_lock (&amp;amp;rwlock);

    if (!array)
      array = g_ptr_array_new ();

    if (index &amp;gt;= array-&amp;gt;len)
      g_ptr_array_set_size (array, index + 1);
    g_ptr_array_index (array, index) = data;

    g_static_rw_lock_writer_unlock (&amp;amp;rwlock);
  }
]|

This example shows an array which can be accessed by many readers
(the my_array_get() function) simultaneously, whereas the writers
(the my_array_set() function) will only be allowed once at a time
and only if no readers currently access the array. This is because
of the potentially dangerous resizing of the array. Using these
functions is fully multi-thread safe now.

Most of the time, writers should have precedence over readers. That
means, for this implementation, that as soon as a writer wants to
lock the data, no other reader is allowed to lock the data, whereas,
of course, the readers that already have locked the data are allowed
to finish their operation. As soon as the last reader unlocks the
data, the writer will lock it.

Even though #GStaticRWLock is not opaque, it should only be used
with the following functions.

All of the g_static_rw_lock_* functions can be used even if
g_thread_init() has not been called. Then they do nothing, apart
from g_static_rw_lock_*_trylock, which does nothing but returning %TRUE.

A read-write lock has a higher overhead than a mutex. For example, both
g_static_rw_lock_reader_lock() and g_static_rw_lock_reader_unlock() have
to lock and unlock a #GStaticMutex, so it takes at least twice the time
to lock and unlock a #GStaticRWLock that it does to lock and unlock a
#GStaticMutex. So only data structures that are accessed by multiple
readers, and which keep the lock for a considerable time justify a
#GStaticRWLock. The above example most probably would fare better with a
#GStaticMutex.&lt;/doc&gt;

multiple times by one thread. If you enter it n times, you have to
unlock it n times again to let other threads lock it. An exception
is the function g_static_rec_mutex_unlock_full(): that allows you to
unlock a #GStaticRecMutex completely returning the depth, (i.e. the
number of times this mutex was locked). The depth can later be used
to restore the state of the #GStaticRecMutex by calling
g_static_rec_mutex_lock_full(). In GLib 2.32, #GStaticRecMutex has
been deprecated in favor of #GRecMutex.

Even though #GStaticRecMutex is not opaque, it should only be used
with the following functions.

All of the g_static_rec_mutex_* functions can be used even if
g_thread_init() has not been called. Then they do nothing, apart
from g_static_rec_mutex_trylock(), which does nothing but returning
%TRUE.&lt;/doc&gt;

The emphasis of `GString` is on text, typically UTF-8. Crucially, the &quot;str&quot; member
of a `GString` is guaranteed to have a trailing nul character, and it is therefore
always safe to call functions such as `strchr()` or `strdup()` on it.

However, a `GString` can also hold arbitrary binary data, because it has a &quot;len&quot; member,
which includes any possible embedded nul characters in the data. Conceptually then,
`GString` is like a `GByteArray` with the addition of many convenience methods for
text, and a guaranteed nul terminator.&lt;/doc&gt;

If @len is positive, @val may contain embedded nuls and need
not be nul-terminated. It is the caller&#039;s responsibility to
ensure that @val has at least @len addressable bytes.

If @len is negative, @val must be nul-terminated and @len
is considered to request the entire string length. This
makes g_string_append_len() equivalent to g_string_append().&lt;/doc&gt;

is considered to request the entire string length. This

           line=&quot;44&quot;&gt;`GStringChunk` provides efficient storage of groups of strings

String chunks are used to store groups of strings. Memory is
allocated in blocks, and as strings are added to the `GStringChunk`
they are copied into the next free position in a block. When a block
is full a new block is allocated.

When storing a large number of strings, string chunks are more
efficient than using [func@GLib.strdup] since fewer calls to `malloc()`
are needed, and less memory is wasted in memory allocation overheads.

By adding strings with [method@GLib.StringChunk.insert_const] it is also
possible to remove duplicates.

To create a new `GStringChunk` use [func@GLib.StringChunk.new].

To add strings to a `GStringChunk` use [method@GLib.StringChunk.insert].

To add strings to a `GStringChunk`, but without duplicating strings
which are already in the `GStringChunk`, use [method@GLib.StringChunk.insert_const].

To free the entire `GStringChunk` use [method@GLib.StringChunk.free].
It is not possible to free individual strings.&lt;/doc&gt;

string has already been added to the #GStringChunk with

This function is useful if you need to copy a large number
of strings but do not want to waste space storing duplicates.
But you must remember that there may be several pointers to
the same string, and so any changes made to the strings
should be done very carefully.

Note that g_string_chunk_insert_const() will not return a
pointer to a string added with g_string_chunk_insert(), even
if they do match.&lt;/doc&gt;

           line=&quot;302&quot;&gt;Creates a unique temporary directory for each unit test and uses
g_set_user_dirs() to set XDG directories to point into subdirectories of it
for the duration of the unit test. The directory tree is cleaned up after the
test finishes successfully. Note that this doesn’t take effect until
g_test_run() is called, so calls to (for example) g_get_user_home_dir() will
return the system-wide value when made in a test program’s main() function.

The following functions will return subdirectories of the temporary directory
when this option is used. The specific subdirectory paths in use are not
guaranteed to be stable API — always use a getter function to retrieve them.

 - g_get_home_dir()
 - g_get_user_cache_dir()
 - g_get_system_config_dirs()
 - g_get_user_config_dir()
 - g_get_system_data_dirs()
 - g_get_user_data_dir()
 - g_get_user_state_dir()
 - g_get_user_runtime_dir()

The subdirectories may not be created by the test harness; as with normal
calls to functions like g_get_user_cache_dir(), the caller must be prepared
to create the directory if it doesn’t exist.&lt;/doc&gt;

These two options correspond rather directly to the &#039;dist&#039; and
&#039;built&#039; terminology that automake uses and are explicitly used to
distinguish between the &#039;srcdir&#039; and &#039;builddir&#039; being separate.  All
files in your project should either be dist (in the
`EXTRA_DIST` or `dist_schema_DATA`
sense, in which case they will always be in the srcdir) or built (in
the `BUILT_SOURCES` sense, in which case they will
always be in the builddir).

Note: as a general rule of automake, files that are generated only as
part of the build-from-git process (but then are distributed with the
tarball) always go in srcdir (even if doing a srcdir != builddir
build from git) and are considered as distributed files.&lt;/doc&gt;

GThread is refcounted, see g_thread_ref() and g_thread_unref().
The thread represented by it holds a reference while it is running,
and g_thread_join() consumes the reference that it is given, so
it is normally not necessary to manage GThread references
explicitly.

             line=&quot;846&quot;&gt;This function creates a new thread. The new thread starts by invoking
@func with the argument data. The thread will run until @func returns
or until g_thread_exit() is called from the new thread. The return value
of @func becomes the return value of the thread, which can be obtained
with g_thread_join().

The @name can be useful for discriminating threads in a debugger.
It is not used for other purposes and does not have to be unique.
Some systems restrict the length of @name to 16 bytes.

If the thread can not be created the program aborts. See
g_thread_try_new() if you want to attempt to deal with failures.

If you are using threads to offload (potentially many) short-lived tasks,
#GThreadPool may be more appropriate than manually spawning and tracking
multiple #GThreads.

To free the struct returned by this function, use g_thread_unref().
Note that g_thread_join() implicitly unrefs the #GThread as well.

New threads by default inherit their scheduler policy (POSIX) or thread
priority (Windows) of the thread creating the new thread.

This behaviour changed in GLib 2.64: before threads on Windows were not
inheriting the thread priority but were spawned with the default priority.
Starting with GLib 2.64 the behaviour is now consistent between Windows and
POSIX and all threads inherit their parent thread&#039;s priority.&lt;/doc&gt;

given to g_thread_new(), returns or g_thread_exit() is called.
If @thread has already terminated, then g_thread_join()
returns immediately.

Any thread can wait for any other thread by calling g_thread_join(),
not just its &#039;creator&#039;. Calling g_thread_join() from multiple threads
for the same @thread leads to undefined behaviour.

The value returned by @func or given to g_thread_exit() is
returned by this function.

g_thread_join() consumes the reference to the passed-in @thread.
This will usually cause the #GThread struct and associated resources
to be freed. Use g_thread_ref() to obtain an extra reference if you
want to keep the GThread alive beyond the g_thread_join() call.&lt;/doc&gt;

If another thread is waiting for us using g_thread_join() then the
waiting thread will be woken up and get @retval as the return value
of g_thread_join().

Calling g_thread_exit() with a parameter @retval is equivalent to
returning @retval from the function @func, as given to g_thread_new().

You must only call g_thread_exit() from a thread that you created
yourself with g_thread_new() or related APIs. You must not call
this function from a thread created with another threading library
or or from within a #GThreadPool.&lt;/doc&gt;

thread system by calling g_thread_init().

Since version 2.24, calling g_thread_init() multiple times is allowed,
but nothing happens except for the first call.

Since version 2.32, GLib does not support custom thread implementations
anymore and the @vtable parameter is ignored and you should pass %NULL.

&amp;lt;note&amp;gt;&amp;lt;para&amp;gt;g_thread_init() must not be called directly or indirectly
in a callback from GLib. Also no mutexes may be currently locked while
calling g_thread_init().&amp;lt;/para&amp;gt;&amp;lt;/note&amp;gt;

&amp;lt;note&amp;gt;&amp;lt;para&amp;gt;To use g_thread_init() in your program, you have to link
with the libraries that the command &amp;lt;command&amp;gt;pkg-config --libs
gthread-2.0&amp;lt;/command&amp;gt; outputs. This is not the case for all the
other thread-related functions of GLib. Those can be used without
having to link with the thread libraries.&amp;lt;/para&amp;gt;&amp;lt;/note&amp;gt;&lt;/doc&gt;
        &lt;doc-deprecated xml:space=&quot;preserve&quot;&gt;This function is no longer necessary. The GLib

           line=&quot;45&quot;&gt;The `GThreadPool` struct represents a thread pool.

A thread pool is useful when you wish to asynchronously fork out the execution of work
and continue working in your own thread. If that will happen often, the overhead of starting
and destroying a thread each time might be too high. In such cases reusing already started
threads seems like a good idea. And it indeed is, but implementing this can be tedious
and error-prone.

Therefore GLib provides thread pools for your convenience. An added advantage is, that the
threads can be shared between the different subsystems of your program, when they are using GLib.

To create a new thread pool, you use [func@GLib.ThreadPool.new].
It is destroyed by [method@GLib.ThreadPool.free].

If you want to execute a certain task within a thread pool, use [method@GLib.ThreadPool.push].

To get the current number of running threads you call [method@GLib.ThreadPool.get_num_threads].
To get the number of still unprocessed tasks you call [method@GLib.ThreadPool.unprocessed].
To control the maximum number of threads for a thread pool, you use
[method@GLib.ThreadPool.get_max_threads]. and [method@GLib.ThreadPool.set_max_threads].

Finally you can control the number of unused threads, that are kept alive by GLib for future use.
The current number can be fetched with [func@GLib.ThreadPool.get_num_unused_threads].
The maximum number can be controlled by [func@GLib.ThreadPool.get_max_unused_threads] and
[func@GLib.ThreadPool.set_max_unused_threads]. All currently unused threads
can be stopped by calling [func@GLib.ThreadPool.stop_unused_threads].&lt;/doc&gt;

If @immediate is %TRUE, no new task is processed for @pool.
Otherwise @pool is not freed before the last task is processed.
Note however, that no thread of this pool is interrupted while
processing a task. Instead at least all still running threads
can finish their tasks before the @pool is freed.

If @wait_ is %TRUE, this function does not return before all
tasks to be processed (dependent on @immediate, whether all
or only the currently running) are ready.
Otherwise this function returns immediately.

After calling this function @pool must not be used anymore.&lt;/doc&gt;

When the number of currently running threads is lower than the
maximal allowed number of threads, a new thread is started (or
reused) with the properties given to g_thread_pool_new().
Otherwise, @data stays in the queue until a thread in this pool
finishes its previous task and processes @data.

@error can be %NULL to ignore errors, or non-%NULL to report
errors. An error can only occur when a new thread couldn&#039;t be
created. In that case @data is simply appended to the queue of
work to do.

A value of -1 means that the maximal number of threads
is unlimited. If @pool is an exclusive thread pool, setting
the maximal number of threads to -1 is not allowed.

Setting @max_threads to 0 means stopping all work for @pool.
It is effectively frozen until @max_threads is set to a non-zero
value again.

A thread is never terminated while calling @func, as supplied by
g_thread_pool_new(). Instead the maximal number of threads only
has effect for the allocation of new threads in g_thread_pool_push().
A new thread is allocated, whenever the number of currently
running threads in @pool is smaller than the maximal number.

@error can be %NULL to ignore errors, or non-%NULL to report
errors. An error can only occur when a new thread couldn&#039;t be
created.

             line=&quot;489&quot;&gt;This function creates a new thread pool.

Whenever you call g_thread_pool_push(), either a new thread is
created or an unused one is reused. At most @max_threads threads
are running concurrently for this thread pool. @max_threads = -1
allows unlimited threads to be created for this thread pool. The
newly created or reused thread now executes the function @func
with the two arguments. The first one is the parameter to
g_thread_pool_push() and the second one is @user_data.

Pass g_get_num_processors() to @max_threads to create as many threads as
there are logical processors on the system. This will not pin each thread to
a specific processor.

The parameter @exclusive determines whether the thread pool owns
all threads exclusive or shares them with other thread pools.
If @exclusive is %TRUE, @max_threads threads are started
immediately and they will run exclusively for this thread pool
until it is destroyed by g_thread_pool_free(). If @exclusive is
%FALSE, threads are created when needed and shared between all
non-exclusive thread pools. This implies that @max_threads may
not be -1 for exclusive thread pools. Besides, exclusive thread
pools are not affected by g_thread_pool_set_max_idle_time()
since their threads are never considered idle and returned to the
global pool.

Note that the threads used by exclusive thread pools will all inherit the
scheduler settings of the current thread while the threads used by
non-exclusive thread pools will inherit the scheduler settings from the
first thread that created such a thread pool.

At least one thread will be spawned when this function is called, either to
create the @max_threads exclusive threads, or to preserve the scheduler
settings of the current thread for future spawns.

@error can be %NULL to ignore errors, or non-%NULL to report
errors. An error can only occur when @exclusive is set to %TRUE
and not all @max_threads threads could be created.
See #GThreadError for possible errors that may occur.
Note, even in case of error a valid #GThreadPool is returned.&lt;/doc&gt;

Second, if the time is in local time, specifies if it is local
standard time or local daylight time.  This is important for the case
where the same local time occurs twice (during daylight savings time

GLib is attempting to unify around the use of 64-bit integers to

             line=&quot;549&quot;&gt;Converts @time_ into an RFC 3339 encoded string, relative to the
Coordinated Universal Time (UTC). This is one of the many formats
allowed by ISO 8601.

ISO 8601 allows a large number of date/time formats, with or without
punctuation and optional elements. The format returned by this function
is a complete date and time, with optional punctuation included, the
UTC time zone represented as &quot;Z&quot;, and the @tv_usec part included if
and only if it is nonzero, i.e. either
&quot;YYYY-MM-DDTHH:MM:SSZ&quot; or &quot;YYYY-MM-DDTHH:MM:SS.fffffZ&quot;.

This corresponds to the Internet date/time format defined by
[RFC 3339](https://www.ietf.org/rfc/rfc3339.txt),
and to either of the two most-precise formats defined by
the W3C Note
[Date and Time Formats](http://www.w3.org/TR/NOTE-datetime-19980827).
Both of these documents are profiles of ISO 8601.

Use g_date_time_format() or g_strdup_printf() if a different
variation of ISO 8601 format is required.

If @time_ represents a date which is too large to fit into a `struct tm`,
%NULL will be returned. This is platform dependent. Note also that since
`GTimeVal` stores the number of seconds as a `glong`, on 32-bit systems it
is subject to the year 2038 problem. Accordingly, since GLib 2.62, this
function has been deprecated. Equivalent functionality is available using:
|[
GDateTime *dt = g_date_time_new_from_unix_utc (time_val);
iso8601_string = g_date_time_format_iso8601 (dt);
g_date_time_unref (dt);
]|

The return value of g_time_val_to_iso8601() has been nullable since GLib
2.54; before then, GLib would crash under the same conditions.&lt;/doc&gt;

to a #GTimeVal and puts it into @time_.

@iso_date must include year, month, day, hours, minutes, and
seconds. It can optionally include fractions of a second and a time
zone indicator. (In the absence of any time zone indication, the
timestamp is assumed to be in local time.)

Any leading or trailing space in @iso_date is ignored.

This function was deprecated, along with #GTimeVal itself, in GLib 2.62.
Equivalent functionality is available using code like:

           line=&quot;55&quot;&gt;A `GTimeZone` represents a time zone, at no particular point in time.

The `GTimeZone` struct is refcounted and immutable.

Each time zone has an identifier (for example, ‘Europe/London’) which is
platform dependent. See [ctor@GLib.TimeZone.new] for information on the
identifier formats. The identifier of a time zone can be retrieved using
[method@GLib.TimeZone.get_identifier].

A time zone contains a number of intervals. Each interval has an abbreviation
to describe it (for example, ‘PDT’), an offset to UTC and a flag indicating
if the daylight savings time is in effect during that interval. A time zone
always has at least one interval — interval 0. Note that interval abbreviations
are not the same as time zone identifiers (apart from ‘UTC’), and cannot be
passed to [ctor@GLib.TimeZone.new].

Every UTC time is contained within exactly one interval, but a given
local time may be contained within zero, one or two intervals (due to
incontinuities associated with daylight savings time).

An interval may refer to a specific period of time (eg: the duration
of daylight savings time during 2010) or it may refer to many periods
of time that share the same properties (eg: all periods of daylight
savings time).  It is also possible (usually for political reasons)
that some properties (like the abbreviation) change between intervals
without other properties changing.&lt;/doc&gt;

             filename=&quot;glib/gtimezone.c&quot;
             line=&quot;1757&quot;&gt;Creates a #GTimeZone corresponding to @identifier. If @identifier cannot be
parsed or loaded, %NULL is returned.

@identifier can either be an RFC3339/ISO 8601 time offset or
something that would pass as a valid value for the `TZ` environment
variable (including %NULL).

In Windows, @identifier can also be the unlocalized name of a time
zone for standard time, for example &quot;Pacific Standard Time&quot;.

Valid RFC3339 time offsets are `&quot;Z&quot;` (for UTC) or
`&quot;±hh:mm&quot;`.  ISO 8601 additionally specifies
`&quot;±hhmm&quot;` and `&quot;±hh&quot;`.  Offsets are
time values to be added to Coordinated Universal Time (UTC) to get
the local time.

In UNIX, the `TZ` environment variable typically corresponds
to the name of a file in the zoneinfo database, an absolute path to a file
somewhere else, or a string in
&quot;std offset [dst [offset],start[/time],end[/time]]&quot; (POSIX) format.
There  are  no spaces in the specification. The name of standard
and daylight savings time zone must be three or more alphabetic
characters. Offsets are time values to be added to local time to
get Coordinated Universal Time (UTC) and should be
`&quot;[±]hh[[:]mm[:ss]]&quot;`.  Dates are either
`&quot;Jn&quot;` (Julian day with n between 1 and 365, leap
years not counted), `&quot;n&quot;` (zero-based Julian day
with n between 0 and 365) or `&quot;Mm.w.d&quot;` (day d
(0 &amp;lt;= d &amp;lt;= 6) of week w (1 &amp;lt;= w &amp;lt;= 5) of month m (1 &amp;lt;= m &amp;lt;= 12), day
0 is a Sunday).  Times are in local wall clock time, the default is
02:00:00.

In Windows, the &quot;tzn[+|–]hh[:mm[:ss]][dzn]&quot; format is used, but also
accepts POSIX format.  The Windows format uses US rules for all time
zones; daylight savings time is 60 minutes behind the standard time
with date and time of change taken from Pacific Standard Time.
Offsets are time values to be added to the local time to get
Coordinated Universal Time (UTC).

g_time_zone_new_local() calls this function with the value of the
`TZ` environment variable. This function itself is independent of
the value of `TZ`, but if @identifier is %NULL then `/etc/localtime`
will be consulted to discover the correct time zone on UNIX and the
registry will be consulted or GetTimeZoneInformation() will be used
to get the local time zone on Windows.

If intervals are not available, only time zone rules from `TZ`
environment variable or other means, then they will be computed
from year 1900 to 2037.  If the maximum year for the rules is
available and it is greater than 2037, then it will followed
instead.

See
[RFC3339 §5.6](http://tools.ietf.org/html/rfc3339#section-5.6)
for a precise definition of valid RFC3339 time offsets
(the `time-offset` expansion) and ISO 8601 for the
full list of valid time offsets.  See
[The GNU C Library manual](http://www.gnu.org/s/libc/manual/html_node/TZ-Variable.html)
for an explanation of the possible
values of the `TZ` environment variable. See

when you are done with it.&lt;/doc&gt;

This is equivalent to calling g_time_zone_new() with the value of

when you are done with it.&lt;/doc&gt;

The meaning of @time_ depends on @type.

This function is similar to g_time_zone_find_interval(), with the
difference that it always succeeds (by making the adjustments
described below).

In any of the cases where g_time_zone_find_interval() succeeds then
this function returns the same value, without modifying @time_.

This function may, however, modify @time_ in order to deal with
non-existent times.  If the non-existent local @time_ of 02:30 were
requested on March 14th 2010 in Toronto then this function would
adjust @time_ to be 03:00 and return the interval containing the
adjusted time.&lt;/doc&gt;

             line=&quot;2310&quot;&gt;Finds an interval within @tz that corresponds to the given @time_.
The meaning of @time_ depends on @type.

If @type is %G_TIME_TYPE_UNIVERSAL then this function will always
succeed (since universal time is monotonic and continuous).

Otherwise @time_ is treated as local time.  The distinction between
%G_TIME_TYPE_STANDARD and %G_TIME_TYPE_DAYLIGHT is ignored except in
the case that the given @time_ is ambiguous.  In Toronto, for example,
01:30 on November 7th 2010 occurred twice (once inside of daylight
savings time and the next, an hour later, outside of daylight savings
time).  In this case, the different value of @type would result in a
different interval being returned.

It is still possible for this function to fail.  In Toronto, for
example, 02:00 on March 14th 2010 does not exist (due to the leap
forward to begin daylight savings time).  -1 is returned in that
case.&lt;/doc&gt;

           line=&quot;36&quot;&gt;A `GTrashStack` is an efficient way to keep a stack of unused allocated
memory chunks. Each memory chunk is required to be large enough to hold
a `gpointer`. This allows the stack to be maintained without any space
overhead, since the stack pointers can be stored inside the memory chunks.

There is no function to create a `GTrashStack`. A `NULL` `GTrashStack*`
is a perfectly valid empty stack.

Each piece of memory that is pushed onto the stack is cast to a
`GTrashStack*`.

There is no longer any good reason to use `GTrashStack`.  If you have
extra pieces of memory, `free()` them and allocate them again later.&lt;/doc&gt;

you supplied a @key_destroy_func when creating the #GTree, the passed
key is freed using that function.

so that the distance from the root to every leaf is as small as possible.

URI scheme, so [method@GLib.Uri.get_scheme] will always return a non-`NULL`
answer. Likewise, by definition, all URIs have a path component, so
[method@GLib.Uri.get_path] will always return a non-`NULL` string (which may
be empty).

If the URI string has an
[‘authority’ component](https://tools.ietf.org/html/rfc3986#section-3) (that
is, if the scheme is followed by `://` rather than just `:`), then the
`GUri` will contain a hostname, and possibly a port and ‘userinfo’.
Additionally, depending on how the `GUri` was constructed/parsed (for example,
using the `G_URI_FLAGS_HAS_PASSWORD` and `G_URI_FLAGS_HAS_AUTH_PARAMS` flags),
the userinfo may be split out into a username, password, and
additional authorization-related parameters.

Normally, the components of a `GUri` will have all `%`-encoded
characters decoded. However, if you construct/parse a `GUri` with
`G_URI_FLAGS_ENCODED`, then the `%`-encoding will be preserved instead in
the userinfo, path, and query fields (and in the host field if also
created with `G_URI_FLAGS_NON_DNS`). In particular, this is necessary if
the URI may contain binary data or non-UTF-8 text, or if decoding
the components might change the interpretation of the URI.

For example, with the encoded flag:

```c
g_autoptr(GUri) uri = g_uri_parse (&quot;http://host/path?query=http%3A%2F%2Fhost%2Fpath%3Fparam%3Dvalue&quot;, G_URI_FLAGS_ENCODED, &amp;amp;err);
g_assert_cmpstr (g_uri_get_query (uri), ==, &quot;query=http%3A%2F%2Fhost%2Fpath%3Fparam%3Dvalue&quot;);
```

While the default `%`-decoding behaviour would give:

```c
g_autoptr(GUri) uri = g_uri_parse (&quot;http://host/path?query=http%3A%2F%2Fhost%2Fpath%3Fparam%3Dvalue&quot;, G_URI_FLAGS_NONE, &amp;amp;err);
g_assert_cmpstr (g_uri_get_query (uri), ==, &quot;query=http://host/path?param=value&quot;);
```

During decoding, if an invalid UTF-8 string is encountered, parsing will fail
with an error indicating the bad string location:

```c
g_autoptr(GUri) uri = g_uri_parse (&quot;http://host/path?query=http%3A%2F%2Fhost%2Fpath%3Fbad%3D%00alue&quot;, G_URI_FLAGS_NONE, &amp;amp;err);
g_assert_error (err, G_URI_ERROR, G_URI_ERROR_BAD_QUERY);
```

You should pass `G_URI_FLAGS_ENCODED` or `G_URI_FLAGS_ENCODED_QUERY` if you
need to handle that case manually. In particular, if the query string
contains `=` characters that are `%`-encoded, you should let
[func@GLib.Uri.parse_params] do the decoding once of the query.

`GUri` is immutable once constructed, and can safely be accessed from
multiple threads. Its reference counting is atomic.

Note that the scope of `GUri` is to help manipulate URIs in various applications,
following [RFC 3986](https://tools.ietf.org/html/rfc3986). In particular,
it doesn&#039;t intend to cover web browser needs, and doesn’t implement the
[WHATWG URL](https://url.spec.whatwg.org/) standard. No APIs are provided to
help prevent
[homograph attacks](https://en.wikipedia.org/wiki/IDN_homograph_attack), so
`GUri` is not suitable for formatting URIs for display to the user for making
security-sensitive decisions.

## Relative and absolute URIs

As defined in [RFC 3986](https://tools.ietf.org/html/rfc3986#section-4), the
hierarchical nature of URIs means that they can either be ‘relative
references’ (sometimes referred to as ‘relative URIs’) or ‘URIs’ (for
clarity, ‘URIs’ are referred to in this documentation as
‘absolute URIs’ — although
[in constrast to RFC 3986](https://tools.ietf.org/html/rfc3986#section-4.3),
fragment identifiers are always allowed).

Relative references have one or more components of the URI missing. In
particular, they have no scheme. Any other component, such as hostname,
query, etc. may be missing, apart from a path, which has to be specified (but
may be empty). The path may be relative, starting with `./` rather than `/`.

For example, a valid relative reference is `./path?query`,
`/?query#fragment` or `//example.com`.

Absolute URIs have a scheme specified. Any other components of the URI which
are missing are specified as explicitly unset in the URI, rather than being
resolved relative to a base URI using [method@GLib.Uri.parse_relative].

For example, a valid absolute URI is `file:///home/bob` or
`https://search.com?query=string`.

A `GUri` instance is always an absolute URI. A string may be an absolute URI
or a relative reference; see the documentation for individual functions as to
what forms they accept.

## Parsing URIs

The most minimalist APIs for parsing URIs are [func@GLib.Uri.split] and
[func@GLib.Uri.split_with_user]. These split a URI into its component
parts, and return the parts; the difference between the two is that
[func@GLib.Uri.split] treats the ‘userinfo’ component of the URI as a
single element, while [func@GLib.Uri.split_with_user] can (depending on the
[flags@GLib.UriFlags] you pass) treat it as containing a username, password,
and authentication parameters. Alternatively, [func@GLib.Uri.split_network]
can be used when you are only interested in the components that are
needed to initiate a network connection to the service (scheme,
host, and port).

[func@GLib.Uri.parse] is similar to [func@GLib.Uri.split], but instead of
returning individual strings, it returns a `GUri` structure (and it requires
that the URI be an absolute URI).

[func@GLib.Uri.resolve_relative] and [method@GLib.Uri.parse_relative] allow
you to resolve a relative URI relative to a base URI.
[func@GLib.Uri.resolve_relative] takes two strings and returns a string,
and [method@GLib.Uri.parse_relative] takes a `GUri` and a string and returns a
`GUri`.

All of the parsing functions take a [flags@GLib.UriFlags] argument describing
exactly how to parse the URI; see the documentation for that type
for more details on the specific flags that you can pass. If you
need to choose different flags based on the type of URI, you can
use [func@GLib.Uri.peek_scheme] on the URI string to check the scheme
first, and use that to decide what flags to parse it with.

For example, you might want to use `G_URI_PARAMS_WWW_FORM` when parsing the
params for a web URI, so compare the result of [func@GLib.Uri.peek_scheme]
against `http` and `https`.

## Building URIs

[func@GLib.Uri.join] and [func@GLib.Uri.join_with_user] can be used to construct
valid URI strings from a set of component strings. They are the
inverse of [func@GLib.Uri.split] and [func@GLib.Uri.split_with_user].

Similarly, [func@GLib.Uri.build] and [func@GLib.Uri.build_with_user] can be
used to construct a `GUri` from a set of component strings.

As with the parsing functions, the building functions take a
[flags@GLib.UriFlags] argument. In particular, it is important to keep in mind
whether the URI components you are using are already `%`-encoded. If so,
you must pass the `G_URI_FLAGS_ENCODED` flag.

## `file://` URIs

Note that Windows and Unix both define special rules for parsing
`file://` URIs (involving non-UTF-8 character sets on Unix, and the
interpretation of path separators on Windows). `GUri` does not
implement these rules. Use [func@GLib.filename_from_uri] and
[func@GLib.filename_to_uri] if you want to properly convert between
`file://` URIs and local filenames.

## URI Equality

Note that there is no `g_uri_equal ()` function, because comparing
URIs usefully requires scheme-specific knowledge that `GUri` does
not have. `GUri` can help with normalization if you use the various
encoded [flags@GLib.UriFlags] as well as `G_URI_FLAGS_SCHEME_NORMALIZE`
however it is not comprehensive.
For example, `data:,foo` and `data:;base64,Zm9v` resolve to the same
thing according to the `data:` URI specification which GLib does not
handle.&lt;/doc&gt;
      &lt;source-position filename=&quot;glib/guri.h&quot; line=&quot;33&quot;/&gt;
      &lt;method name=&quot;get_auth_params&quot;
              c:identifier=&quot;g_uri_get_auth_params&quot;
              version=&quot;2.66&quot;&gt;

             filename=&quot;glib/guri.c&quot;
             line=&quot;2439&quot;&gt;Gets @uri&#039;s authentication parameters, which may contain
`%`-encoding, depending on the flags with which @uri was created.
(If @uri was not created with %G_URI_FLAGS_HAS_AUTH_PARAMS then this will
be %NULL.)

Depending on the URI scheme, g_uri_parse_params() may be useful for
further parsing this information.&lt;/doc&gt;

This is not guaranteed to return a string which is identical to the
string that @uri was parsed from. However, if the source URI was
syntactically correct (according to RFC 3986), and it was parsed
with %G_URI_FLAGS_ENCODED, then g_uri_to_string() is guaranteed to return
a string which is at least semantically equivalent to the source
URI (according to RFC 3986).

If @uri might contain sensitive details, such as authentication parameters,
or private data in its query string, and the returned string is going to be
logged, then consider using g_uri_to_string_partial() to redact parts.&lt;/doc&gt;

             line=&quot;2272&quot;&gt;Many URI schemes include one or more attribute/value pairs as part of the URI
value. This method can be used to parse them into a hash table. When an
attribute has multiple occurrences, the last value is the final returned
value. If you need to handle repeated attributes differently, use
#GUriParamsIter.

The @params string is assumed to still be `%`-encoded, but the returned
values will be fully decoded. (Thus it is possible that the returned values
may contain `=` or @separators, if the value was encoded in the input.)
Invalid `%`-encoding is treated as with the %G_URI_FLAGS_PARSE_RELAXED
rules for g_uri_parse(). (However, if @params is the path or query string
from a #GUri that was parsed without %G_URI_FLAGS_PARSE_RELAXED and
%G_URI_FLAGS_ENCODED, then you already know that it does not contain any
invalid encoding.)

%G_URI_PARAMS_WWW_FORM is handled as documented for g_uri_params_iter_init().

If %G_URI_PARAMS_CASE_INSENSITIVE is passed to @flags, attributes will be
compared case-insensitively, so a params string `attr=123&amp;amp;Attr=456` will only
return a single attribute–value pair, `Attr=456`. Case will be preserved in
the returned attributes.

If @params cannot be parsed (for example, it contains two @separators
characters in a row), then @error is set and %NULL is returned.&lt;/doc&gt;

[RFC 3986](https://tools.ietf.org/html/rfc3986#section-3) decodes the scheme
as:

URI = scheme &quot;:&quot; hier-part [ &quot;?&quot; query ] [ &quot;#&quot; fragment ]
]|
Common schemes include `file`, `https`, `svn+ssh`, etc.

Unlike g_uri_parse_scheme(), the returned scheme is normalized to
all-lowercase and does not need to be freed.&lt;/doc&gt;

returns the pieces. Any component that doesn&#039;t appear in @uri_ref will be
returned as %NULL (but note that all URIs always have a path component,
though it may be the empty string).

If @flags contains %G_URI_FLAGS_ENCODED, then `%`-encoded characters in
@uri_ref will remain encoded in the output strings. (If not,
then all such characters will be decoded.) Note that decoding will
only work if the URI components are ASCII or UTF-8, so you will
need to use %G_URI_FLAGS_ENCODED if they are not.

Note that the %G_URI_FLAGS_HAS_PASSWORD and
%G_URI_FLAGS_HAS_AUTH_PARAMS @flags are ignored by g_uri_split(),
since it always returns only the full userinfo; use
g_uri_split_with_user() if you want it split up.&lt;/doc&gt;

%G_URI_FLAGS_HAS_AUTH_PARAMS.&lt;/doc&gt;

A #GUriParamsIter structure represents an iterator that can be used to
iterate over the attribute/value pairs of a URI query string. #GUriParamsIter

g_uri_params_iter_init(). See the documentation for g_uri_params_iter_init()

             line=&quot;2103&quot;&gt;Initializes an attribute/value pair iterator.

The iterator keeps pointers to the @params and @separators arguments, those
variables must thus outlive the iterator and not be modified during the
iteration.

If %G_URI_PARAMS_WWW_FORM is passed in @flags, `+` characters in the param
string will be replaced with spaces in the output. For example, `foo=bar+baz`
will give attribute `foo` with value `bar baz`. This is commonly used on the
web (the `https` and `http` schemes only), but is deprecated in favour of
the equivalent of encoding spaces as `%20`.

Unlike with g_uri_parse_params(), %G_URI_PARAMS_CASE_INSENSITIVE has no
effect if passed to @flags for g_uri_params_iter_init(). The caller is
responsible for doing their own case-insensitive comparisons.

           line=&quot;38&quot;&gt;`GVariant` is a variant datatype; it can contain one or more values
along with information about the type of the values.

A `GVariant` may contain simple types, like an integer, or a boolean value;
or complex types, like an array of two strings, or a dictionary of key
value pairs. A `GVariant` is also immutable: once it’s been created neither
its type nor its content can be modified further.

`GVariant` is useful whenever data needs to be serialized, for example when
sending method parameters in D-Bus, or when saving settings using
[`GSettings`](../gio/class.Settings.html).

When creating a new `GVariant`, you pass the data you want to store in it
along with a string representing the type of data you wish to pass to it.

For instance, if you want to create a `GVariant` holding an integer value you
can use:

```c
GVariant *v = g_variant_new (&quot;u&quot;, 40);
```

The string `u` in the first argument tells `GVariant` that the data passed to
the constructor (`40`) is going to be an unsigned integer.

More advanced examples of `GVariant` in use can be found in documentation for
[`GVariant` format strings](gvariant-format-strings.html#pointers).

The range of possible values is determined by the type.

The type system used by `GVariant` is [type@GLib.VariantType].

`GVariant` instances always have a type and a value (which are given
at construction time).  The type and value of a `GVariant` instance
can never change other than by the `GVariant` itself being
destroyed.  A `GVariant` cannot contain a pointer.

`GVariant` is reference counted using [method@GLib.Variant.ref] and
[method@GLib.Variant.unref].  `GVariant` also has floating reference counts —
see [method@GLib.Variant.ref_sink].

`GVariant` is completely threadsafe.  A `GVariant` instance can be
concurrently accessed in any way from any number of threads without
problems.

`GVariant` is heavily optimised for dealing with data in serialized
form.  It works particularly well with data located in memory-mapped
files.  It can perform nearly all deserialization operations in a
small constant time, usually touching only a single memory page.
Serialized `GVariant` data can also be sent over the network.

`GVariant` is largely compatible with D-Bus.  Almost all types of
`GVariant` instances can be sent over D-Bus.  See [type@GLib.VariantType] for
exceptions.  (However, `GVariant`’s serialization format is not the same
as the serialization format of a D-Bus message body: use
[GDBusMessage](../gio/class.DBusMessage.html), in the GIO library, for those.)

For space-efficiency, the `GVariant` serialization format does not
automatically include the variant’s length, type or endianness,
which must either be implied from context (such as knowledge that a
particular file format always contains a little-endian
`G_VARIANT_TYPE_VARIANT` which occupies the whole length of the file)
or supplied out-of-band (for instance, a length, type and/or endianness
indicator could be placed at the beginning of a file, network message
or network stream).

A `GVariant`’s size is limited mainly by any lower level operating
system constraints, such as the number of bits in `gsize`.  For
example, it is reasonable to have a 2GB file mapped into memory
with [struct@GLib.MappedFile], and call [ctor@GLib.Variant.new_from_data] on
it.

For convenience to C programmers, `GVariant` features powerful
varargs-based value construction and destruction.  This feature is
designed to be embedded in other libraries.

There is a Python-inspired text language for describing `GVariant`
values.  `GVariant` includes a printer for this language and a parser
with type inferencing.

## Memory Use

`GVariant` tries to be quite efficient with respect to memory use.
This section gives a rough idea of how much memory is used by the
current implementation.  The information here is subject to change
in the future.

The memory allocated by `GVariant` can be grouped into 4 broad
purposes: memory for serialized data, memory for the type
information cache, buffer management memory and memory for the
`GVariant` structure itself.

## Serialized Data Memory

This is the memory that is used for storing `GVariant` data in
serialized form.  This is what would be sent over the network or
what would end up on disk, not counting any indicator of the
endianness, or of the length or type of the top-level variant.

The amount of memory required to store a boolean is 1 byte. 16,
32 and 64 bit integers and double precision floating point numbers
use their ‘natural’ size.  Strings (including object path and
signature strings) are stored with a nul terminator, and as such
use the length of the string plus 1 byte.

‘Maybe’ types use no space at all to represent the null value and
use the same amount of space (sometimes plus one byte) as the
equivalent non-maybe-typed value to represent the non-null case.

Arrays use the amount of space required to store each of their
members, concatenated.  Additionally, if the items stored in an
array are not of a fixed-size (ie: strings, other arrays, etc)
then an additional framing offset is stored for each item.  The
size of this offset is either 1, 2 or 4 bytes depending on the
overall size of the container.  Additionally, extra padding bytes
are added as required for alignment of child values.

Tuples (including dictionary entries) use the amount of space
required to store each of their members, concatenated, plus one
framing offset (as per arrays) for each non-fixed-sized item in
the tuple, except for the last one.  Additionally, extra padding
bytes are added as required for alignment of child values.

Variants use the same amount of space as the item inside of the
variant, plus 1 byte, plus the length of the type string for the
item inside the variant.

As an example, consider a dictionary mapping strings to variants.
In the case that the dictionary is empty, 0 bytes are required for
the serialization.

If we add an item ‘width’ that maps to the int32 value of 500 then
we will use 4 bytes to store the int32 (so 6 for the variant
containing it) and 6 bytes for the string.  The variant must be
aligned to 8 after the 6 bytes of the string, so that’s 2 extra
bytes.  6 (string) + 2 (padding) + 6 (variant) is 14 bytes used
for the dictionary entry.  An additional 1 byte is added to the
array as a framing offset making a total of 15 bytes.

If we add another entry, ‘title’ that maps to a nullable string
that happens to have a value of null, then we use 0 bytes for the
null value (and 3 bytes for the variant to contain it along with
its type string) plus 6 bytes for the string.  Again, we need 2
padding bytes.  That makes a total of 6 + 2 + 3 = 11 bytes.

We now require extra padding between the two items in the array.
After the 14 bytes of the first item, that’s 2 bytes required.
We now require 2 framing offsets for an extra two
bytes. 14 + 2 + 11 + 2 = 29 bytes to encode the entire two-item
dictionary.

## Type Information Cache

For each `GVariant` type that currently exists in the program a type
information structure is kept in the type information cache.  The
type information structure is required for rapid deserialization.

Continuing with the above example, if a `GVariant` exists with the
type `a{sv}` then a type information struct will exist for
`a{sv}`, `{sv}`, `s`, and `v`.  Multiple uses of the same type
will share the same type information.  Additionally, all
single-digit types are stored in read-only static memory and do
not contribute to the writable memory footprint of a program using
`GVariant`.

Aside from the type information structures stored in read-only
memory, there are two forms of type information.  One is used for
container types where there is a single element type: arrays and
maybe types.  The other is used for container types where there
are multiple element types: tuples and dictionary entries.

Array type info structures are `6 * sizeof (void *)`, plus the
memory required to store the type string itself.  This means that
on 32-bit systems, the cache entry for `a{sv}` would require 30
bytes of memory (plus allocation overhead).

Tuple type info structures are `6 * sizeof (void *)`, plus `4 *
sizeof (void *)` for each item in the tuple, plus the memory
required to store the type string itself.  A 2-item tuple, for
example, would have a type information structure that consumed
writable memory in the size of `14 * sizeof (void *)` (plus type
string)  This means that on 32-bit systems, the cache entry for
`{sv}` would require 61 bytes of memory (plus allocation overhead).

This means that in total, for our `a{sv}` example, 91 bytes of
type information would be allocated.

The type information cache, additionally, uses a [struct@GLib.HashTable] to
store and look up the cached items and stores a pointer to this
hash table in static storage.  The hash table is freed when there
are zero items in the type cache.

Although these sizes may seem large it is important to remember
that a program will probably only have a very small number of
different types of values in it and that only one type information
structure is required for many different values of the same type.

## Buffer Management Memory

`GVariant` uses an internal buffer management structure to deal
with the various different possible sources of serialized data
that it uses.  The buffer is responsible for ensuring that the
correct call is made when the data is no longer in use by
`GVariant`.  This may involve a [func@GLib.free] or
even [method@GLib.MappedFile.unref].

One buffer management structure is used for each chunk of
serialized data.  The size of the buffer management structure
is `4 * (void *)`.  On 32-bit systems, that’s 16 bytes.

## GVariant structure

The size of a `GVariant` structure is `6 * (void *)`.  On 32-bit
systems, that’s 24 bytes.

`GVariant` structures only exist if they are explicitly created
with API calls.  For example, if a `GVariant` is constructed out of
serialized data for the example given above (with the dictionary)
then although there are 9 individual values that comprise the
entire dictionary (two keys, two values, two variants containing
the values, two dictionary entries, plus the dictionary itself),
only 1 `GVariant` instance exists — the one referring to the
dictionary.

If calls are made to start accessing the other values then
`GVariant` instances will exist for those values only for as long
as they are in use (ie: until you call [method@GLib.Variant.unref]).  The
type information is shared.  The serialized data and the buffer
management structure for that serialized data is shared by the
child.

## Summary

To put the entire example together, for our dictionary mapping
strings to variants (with two entries, as given above), we are
using 91 bytes of memory for type information, 29 bytes of memory
for the serialized data, 16 bytes for buffer management and 24
bytes for the `GVariant` instance, or a total of 160 bytes, plus
allocation overhead.  If we were to use [method@GLib.Variant.get_child_value]
to access the two dictionary entries, we would use an additional 48
bytes.  If we were to have other dictionaries of the same type, we
would use more memory for the serialized data and buffer
management for those dictionaries, but the type information would
be shared.&lt;/doc&gt;

             line=&quot;5364&quot;&gt;Creates a new #GVariant instance.

Think of this function as an analogue to g_strdup_printf().

The type of the created instance and the arguments that are expected
by this function are determined by @format_string. See the section on
[GVariant format strings][gvariant-format-strings]. Please note that
the syntax of the format string is very likely to be extended in the
future.

The first character of the format string must not be &#039;*&#039; &#039;?&#039; &#039;@&#039; or
&#039;r&#039;; in essence, a new #GVariant must always be constructed by this
function (and not merely passed through it unmodified).

Note that the arguments must be of the correct width for their types
specified in @format_string. This can be achieved by casting them. See
the [GVariant varargs documentation][gvariant-varargs].

@child_type must be non-%NULL if @n_children is zero.  Otherwise, the
child type is determined by inspecting the first element of the
@children array.  If @child_type is non-%NULL then it must be a
definite type.

The items of the array are taken from the @children array.  No entry
in the @children array may be %NULL.

All items in the array must have the same type, which must be the
same as @child_type, if given.

If the @children are floating references (see g_variant_ref_sink()), the
new instance takes ownership of them as if via g_variant_ref_sink().&lt;/doc&gt;

@element_size must be the size of a single element in the array.

you might say sizeof(gint32). This value isn&#039;t used except for the purpose
of a double-check that the form of the serialized data matches the caller&#039;s
expectation.

             line=&quot;6164&quot;&gt;Creates a new #GVariant instance from serialized data.

@type is the type of #GVariant instance that will be constructed.
The interpretation of @data depends on knowing the type.

@data is not modified by this function and must remain valid with an
unchanging value until such a time as @notify is called with
@user_data.  If the contents of @data change before that time then
the result is undefined.

If @data is trusted to be serialized data in normal form then
@trusted should be %TRUE.  This applies to serialized data created
within this process or read from a trusted location on the disk (such
as a file installed in /usr/lib alongside your application).  You
should set trusted to %FALSE if @data is read from the network, a
file in the user&#039;s home directory, etc.

If @data was not stored in this machine&#039;s native endianness, any multi-byte
numeric values in the returned variant will also be in non-native
endianness. g_variant_byteswap() can be used to recover the original values.

@notify will be called with @user_data when @data is no longer
needed.  The exact time of this call is unspecified and might even be
before this function returns.

Note: @data must be backed by memory that is aligned appropriately for the
@type being loaded. Otherwise this function will internally create a copy of
the memory (since GLib 2.60) or (in older versions) fail and exit the
process.&lt;/doc&gt;

             line=&quot;2650&quot;&gt;Parses @format and returns the result.

@format must be a text format #GVariant with one extension: at any
point that a value may appear in the text, a &#039;%&#039; character followed
by a GVariant format string (as per g_variant_new()) may appear.  In
that case, the same arguments are collected from the argument list as
g_variant_new() would have collected.

Note that the arguments must be of the correct width for their types
specified in @format. This can be achieved by casting them. See
the [GVariant varargs documentation][gvariant-varargs].

Consider this simple example:
|[&amp;lt;!-- language=&quot;C&quot; --&amp;gt;
 g_variant_new_parsed (&quot;[(&#039;one&#039;, 1), (&#039;two&#039;, %i), (%s, 3)]&quot;, 2, &quot;three&quot;);
]|

In the example, the variable argument parameters are collected and
filled in as if they were part of the original string to produce the
result of
|[&amp;lt;!-- language=&quot;C&quot; --&amp;gt;
[(&#039;one&#039;, 1), (&#039;two&#039;, 2), (&#039;three&#039;, 3)]
]|

This function is intended only to be used with @format as a string
literal.  Any parse error is fatal to the calling process.  If you
want to parse data from untrusted sources, use g_variant_parse().

You may not use this function to return, unmodified, a single
#GVariant pointer from the argument list.  ie: @format may not solely
be anything along the lines of &quot;%*&quot;, &quot;%?&quot;, &quot;\%r&quot;, or anything starting
with &quot;%@&quot;.&lt;/doc&gt;

             line=&quot;2588&quot;&gt;Parses @format and returns the result.

This is the version of g_variant_new_parsed() intended to be used
from libraries.

The return value will be floating if it was a newly created GVariant
instance.  In the case that @format simply specified the collection
of a #GVariant pointer (eg: @format was &quot;%*&quot;) then the collected
#GVariant pointer will be returned unmodified, without adding any
additional references.

Note that the arguments in @app must be of the correct width for their types
specified in @format when collected into the #va_list. See
the [GVariant varargs documentation][gvariant-varargs].

In order to behave correctly in all cases it is necessary for the
calling function to g_variant_ref_sink() the return result before
returning control to the user that originally provided the pointer.
At this point, the caller will have their own full reference to the
result.  This can also be done by adding the result to a container,
or by passing it to another g_variant_new() call.&lt;/doc&gt;

             line=&quot;5421&quot;&gt;This function is intended to be used by libraries based on
#GVariant that want to provide g_variant_new()-like functionality
to their users.

The API is more general than g_variant_new() to allow a wider range
of possible uses.

@format_string must still point to a valid format string, but it only
needs to be nul-terminated if @endptr is %NULL.  If @endptr is
non-%NULL then it is updated to point to the first character past the
end of the format string.

@app is a pointer to a #va_list.  The arguments, according to
@format_string, are collected from this #va_list and the list is left
pointing to the argument following the last.

Note that the arguments in @app must be of the correct width for their
types specified in @format_string when collected into the #va_list.
See the [GVariant varargs documentation][gvariant-varargs].

These two generalisations allow mixing of multiple calls to
g_variant_new_va() and g_variant_get_va() within a single actual
varargs call by the user.

The return value will be floating if it was a newly created GVariant
instance (for example, if the format string was &quot;(ii)&quot;).  In the case
that the format_string was &#039;*&#039;, &#039;?&#039;, &#039;r&#039;, or a format starting with
&#039;@&#039; then the collected #GVariant pointer will be returned unmodified,
without adding any additional references.

In order to behave correctly in all cases it is necessary for the
calling function to g_variant_ref_sink() the return result before
returning control to the user that originally provided the pointer.
At this point, the caller will have their own full reference to the
result.  This can also be done by adding the result to a container,
or by passing it to another g_variant_new() call.&lt;/doc&gt;

This function is an identity mapping on any value that does not
contain multi-byte numeric data.  That include strings, booleans,
bytes and containers containing only these things (recursively).

While this function can safely handle untrusted, non-normal data, it is
recommended to check whether the input is in normal form beforehand, using
g_variant_is_normal_form(), and to reject non-normal inputs if your
application can be strict about what inputs it rejects.

The returned value is always in normal form and is marked as trusted.
A full, not floating, reference is returned.&lt;/doc&gt;

If @copy_only is %TRUE then this function additionally checks that it
would be safe to call g_variant_unref() on @value immediately after
the call to g_variant_get() without invalidating the result.  This is
only possible if deep copies are made (ie: there are no pointers to
the data inside of the soon-to-be-freed #GVariant instance).  If this
check fails then a g_critical() is printed and %FALSE is returned.

This function is meant to be used by functions that wish to provide
varargs accessors to #GVariant values of uncertain values (eg:
g_variant_lookup() or g_menu_model_get_item_attribute()).&lt;/doc&gt;

The types of @one and @two are #gconstpointer only to allow use of
this function with #GTree, #GPtrArray, etc.  They must each be a
#GVariant.

Comparison is only defined for basic types (ie: booleans, numbers,
strings).  For booleans, %FALSE is less than %TRUE.  Numbers are
ordered in the usual way.  Strings are in ASCII lexographical order.

It is a programmer error to attempt to compare container values or
two values that have types that are not exactly equal.  For example,
you cannot compare a 32-bit signed integer with a 32-bit unsigned
integer.  Also note that this function is not particularly
well-behaved when it comes to comparison of doubles; in particular,
the handling of incomparable values (ie: NaN) is undefined.

If you only require an equality comparison, g_variant_equal() is more
general.&lt;/doc&gt;

Think of this function as an analogue to scanf().

The arguments that are expected by this function are entirely
determined by @format_string.  @format_string also restricts the
permissible types of @value.  It is an error to give a value with
an incompatible type.  See the section on
[GVariant format strings][gvariant-format-strings].
Please note that the syntax of the format string is very likely to be
extended in the future.

@format_string determines the C types that are used for unpacking
the values and also determines if the values are copied or borrowed,
see the section on
[`GVariant` format strings](gvariant-format-strings.html#pointers).&lt;/doc&gt;

entries.  It is an error to call this function on any other type of
#GVariant.

It is an error if @index_ is greater than the number of child items
in the container.  See g_variant_n_children().

The returned value is never floating.  You should free it with
g_variant_unref() when you&#039;re done with it.

Note that values borrowed from the returned child are not guaranteed to
still be valid after the child is freed even if you still hold a reference
to @value, if @value has not been serialized at the time this function is
called. To avoid this, you can serialize @value by calling
g_variant_get_data() and optionally ignoring the return value.

There may be implementation specific restrictions on deeply nested values,
which would result in the unit tuple being returned as the child value,
instead of further nested children. #GVariant is guaranteed to handle
nesting up to at least 64 levels.

This function is O(1).&lt;/doc&gt;

             line=&quot;990&quot;&gt;Returns a pointer to the serialized form of a #GVariant instance.
The returned data may not be in fully-normalised form if read from an
untrusted source.  The returned data must not be freed; it remains
valid for as long as @value exists.

If @value is a fixed-sized value that was deserialized from a
corrupted serialized container then %NULL may be returned.  In this
case, the proper thing to do is typically to use the appropriate
number of nul bytes in place of @value.  If @value is not fixed-sized
then %NULL is never returned.

In the case that @value is already in serialized form, this function
is O(1).  If the value is not already in serialized form,
serialization occurs implicitly and is approximately O(n) in the size
of the result.

To deserialize the data returned by this function, in addition to the
serialized data, you must know the type of the #GVariant, and (if the
machine might be different) the endianness of the machine that stored
it. As a result, file formats or network messages that incorporate
serialized #GVariants must include this information either
implicitly (for instance &quot;the file always contains a

             line=&quot;1101&quot;&gt;Provides access to the serialized data for an array of fixed-sized
items.

@value must be an array with fixed-sized elements.  Numeric types are
fixed-size, as are tuples containing only other fixed-sized types.

@element_size must be the size of a single element in the array,
as given by the section on
[serialized data memory][gvariant-serialized-data-memory].

In particular, arrays of these fixed-sized types can be interpreted
as an array of the given C type, with @element_size set to the size
the appropriate type:
- %G_VARIANT_TYPE_INT16 (etc.): #gint16 (etc.)
- %G_VARIANT_TYPE_BOOLEAN: #guchar (not #gboolean!)
- %G_VARIANT_TYPE_BYTE: #guint8
- %G_VARIANT_TYPE_HANDLE: #guint32
- %G_VARIANT_TYPE_DOUBLE: #gdouble

For example, if calling this function for an array of 32-bit integers,
you might say `sizeof(gint32)`. This value isn&#039;t used except for the purpose
of a double-check that the form of the serialized data matches the caller&#039;s
expectation.

@n_elements, which must be non-%NULL, is set equal to the number of
items in the array.&lt;/doc&gt;

trusted to be in normal form.

If @value is already trusted to be in normal form then a new
reference to @value is returned.

If @value is not already trusted, then it is scanned to check if it
is in normal form.  If it is found to be in normal form then it is
marked as trusted and a new reference to it is returned.

If @value is found not to be in normal form then a new trusted
#GVariant is created with the same value as @value. The non-normal parts of
@value will be replaced with default values which are guaranteed to be in
normal form.

It makes sense to call this function if you&#039;ve received #GVariant
data from untrusted sources and you want to ensure your serialized
output is definitely in normal form.

If @value is already in normal form, a new reference will be returned
(which will be floating if @value is floating). If it is not in normal form,
the newly created #GVariant will be returned with a single non-floating
reference. Typically, g_variant_take_ref() should be called on the return
value from this function to guarantee ownership of a single non-floating
reference to it.&lt;/doc&gt;

%G_VARIANT_TYPE_OBJECT_PATH and %G_VARIANT_TYPE_SIGNATURE.

The string will always be UTF-8 encoded, will never be %NULL, and will never
contain nul bytes.

If @length is non-%NULL then the length of the string (in bytes) is
returned there.  For trusted values, this information is already
known.  Untrusted values will be validated and, if valid, a strlen() will be
performed. If invalid, a default value will be returned — for
%G_VARIANT_TYPE_OBJECT_PATH, this is `&quot;/&quot;`, and for other types it is the
empty string.

It is an error to call this function with a @value of any type
other than those three.

The return value remains valid as long as @value exists.&lt;/doc&gt;

             line=&quot;5532&quot;&gt;This function is intended to be used by libraries based on #GVariant
that want to provide g_variant_get()-like functionality to their
users.

The API is more general than g_variant_get() to allow a wider range
of possible uses.

@format_string must still point to a valid format string, but it only
need to be nul-terminated if @endptr is %NULL.  If @endptr is
non-%NULL then it is updated to point to the first character past the
end of the format string.

@app is a pointer to a #va_list.  The arguments, according to
@format_string, are collected from this #va_list and the list is left
pointing to the argument following the last.

These two generalisations allow mixing of multiple calls to
g_variant_new_va() and g_variant_get_va() within a single actual
varargs call by the user.

@format_string determines the C types that are used for unpacking
the values and also determines if the values are copied or borrowed,
see the section on
[`GVariant` format strings](gvariant-format-strings.html#pointers).&lt;/doc&gt;

             line=&quot;1332&quot;&gt;Checks if @value is in normal form.

The main reason to do this is to detect if a given chunk of
serialized data is in normal form: load the data into a #GVariant
using g_variant_new_from_data() and then use this function to
check.

If @value is found to be in normal form then it will be marked as
being trusted.  If the value was already marked as being trusted then
this function will immediately return %TRUE.

There may be implementation specific restrictions on deeply nested values.
GVariant is guaranteed to handle nesting up to at least 64 levels.&lt;/doc&gt;

This function is a wrapper around g_variant_lookup_value() and
g_variant_get().  In the case that %NULL would have been returned,
this function returns %FALSE.  Otherwise, it unpacks the returned
value and returns %TRUE.

@format_string determines the C types that are used for unpacking
the values and also determines if the values are copied or borrowed,
see the section on
[`GVariant` format strings](gvariant-format-strings.html#pointers).

This function is currently implemented with a linear scan.  If you
plan to do many lookups then #GVariantDict may be more efficient.&lt;/doc&gt;

             line=&quot;1009&quot;&gt;Looks up a value in a dictionary #GVariant.

This function works with dictionaries of the type a{s*} (and equally
well with type a{o*}, but we only further discuss the string case
for sake of clarity).

In the event that @dictionary has the type a{sv}, the @expected_type
string specifies what type of value is expected to be inside of the
variant. If the value inside the variant has a different type then
%NULL is returned. In the event that @dictionary has a value type other
than v then @expected_type must directly match the value type and it is
used to unpack the value directly or an error occurs.

In either case, if @key is not found in @dictionary, %NULL is returned.

If the key is found and the value has the correct type, it is
returned.  If @expected_type was specified then any non-%NULL return
value will have this type.

This function is currently implemented with a linear scan.  If you
plan to do many lookups then #GVariantDict may be more efficient.&lt;/doc&gt;

             line=&quot;832&quot;&gt;#GVariant uses a floating reference count system.  All functions with
names starting with `g_variant_new_` return floating
references.

Calling g_variant_ref_sink() on a #GVariant with a floating reference
will convert the floating reference into a full reference.  Calling
g_variant_ref_sink() on a non-floating #GVariant results in an
additional normal reference being added.

In other words, if the @value is floating, then this call &quot;assumes
ownership&quot; of the floating reference, converting it to a normal
reference.  If the @value is not floating, then this call adds a
new normal reference increasing the reference count by one.

All calls that result in a #GVariant instance being inserted into a
container will call g_variant_ref_sink() on the instance.  This means
that if the value was just created (and has only its floating
reference) then the container will assume sole ownership of the value
at that point and the caller will not need to unreference it.  This
makes certain common styles of programming much easier while still
maintaining normal refcounting semantics in situations where values
are not floating.&lt;/doc&gt;

The stored data is in machine native byte order but may not be in

g_variant_get_normal_form() for a solution.

As with g_variant_get_data(), to be able to deserialize the
serialized variant successfully, its type and (if the destination
machine might be different) its endianness must also be available.

This function is approximately O(n) in the size of @data.&lt;/doc&gt;

Typically you want to use g_variant_ref_sink() in order to
automatically do the correct thing with respect to floating or
non-floating references, but there is one specific scenario where
this function is helpful.

The situation where this function is helpful is when creating an API
that allows the user to provide a callback function that returns a
#GVariant.  We certainly want to allow the user the flexibility to
return a non-floating reference from this callback (for the case
where the value that is being returned already exists).

At the same time, the style of the #GVariant API makes it likely that
for newly-created #GVariant instances, the user can be saved some
typing if they are allowed to return a #GVariant with a floating
reference.

Using this function on the return value of the user&#039;s callback allows
the user to do whichever is more convenient for them.  The caller
will always receives exactly one full reference to the value: either
the one that was returned in the first place, or a floating reference
that has been converted to a full reference.

This function has an odd interaction when combined with
g_variant_ref_sink() running at the same time in another thread on
the same #GVariant instance.  If g_variant_ref_sink() runs first then
the result will be that the floating reference is converted to a hard
reference.  If g_variant_take_ref() runs first then the result will
be that the floating reference is converted to a hard reference and
an additional reference on top of that one is added.  It is best to
avoid this situation.&lt;/doc&gt;

             line=&quot;2483&quot;&gt;Parses a #GVariant from a text representation.

A single #GVariant is parsed from the content of @text.

The format is described [here](gvariant-text-format.html).

The memory at @limit will never be accessed and the parser behaves as
if the character at @limit is the nul terminator.  This has the
effect of bounding @text.

If @endptr is non-%NULL then @text is permitted to contain data
following the value that this function parses and @endptr will be
updated to point to the first character past the end of the text
parsed by this function.  If @endptr is %NULL and there is extra data
then an error is returned.

If @type is non-%NULL then the value will be parsed to have that
type.  This may result in additional parse errors (in the case that
the parsed value doesn&#039;t fit the type) but may also result in fewer
errors (in the case that the type would have been ambiguous, such as
with empty arrays).

In the event that the parsing is successful, the resulting #GVariant
is returned. It is never floating, and must be freed with
[method@GLib.Variant.unref].

In case of any error, %NULL will be returned.  If @error is non-%NULL
then it will be set to reflect the error that occurred.

Officially, the language understood by the parser is “any string
produced by [method@GLib.Variant.print]”. This explicitly includes
`g_variant_print()`’s annotated types like `int64 -1000`.

There may be implementation specific restrictions on deeply nested values,
which would result in a %G_VARIANT_PARSE_ERROR_RECURSION error. #GVariant is
guaranteed to handle nesting up to at least 64 levels.&lt;/doc&gt;

error within the string for which parsing was attempted.

The resulting string is suitable for output to the console or other
monospace media where newlines are treated in the usual way.

The message will typically look something like one of the following:

|[
unterminated string constant:
  (1, 2, 3, &#039;abc
            ^^^^
]|

or

|[
unable to find a common type:
  [1, 2, 3, &#039;str&#039;]
   ^        ^^^^^
]|

The format of the message may change in a future version.

@error must have come from a failed attempt to g_variant_parse() and
@source_str must be exactly the same string that caused the error.
If @source_str was not nul-terminated when you passed it to
g_variant_parse() then you must add nul termination before using this
function.&lt;/doc&gt;

It is an error to call this function in any way that would create an

putting different types of items into an array, putting the wrong
types or number of items in a tuple, putting more than one value into
a variant, etc.

If @value is a floating reference (see g_variant_ref_sink()),
the @builder instance takes ownership of @value.&lt;/doc&gt;

It typically only makes sense to do this on a stack-allocated
#GVariantBuilder if you want to abort building the value part-way
through.  This function need not be called if you call
g_variant_builder_end() and it also doesn&#039;t need to be called on
builders allocated with g_variant_builder_new() (see
g_variant_builder_unref() for that).

This function leaves the #GVariantBuilder structure set to all-zeros.
It is valid to call this function on either an initialised
#GVariantBuilder or one that is set to all-zeros but it is not valid
to call this function on uninitialised memory.&lt;/doc&gt;

It is not permissible to use @builder in any way after this call
except for reference counting operations (in the case of a
heap-allocated #GVariantBuilder) or by reinitialising it with
g_variant_builder_init() (in the case of stack-allocated). This
means that for the stack-allocated builders there is no need to
call g_variant_builder_clear() after the call to
g_variant_builder_end().

It is an error to call this function in any way that would create an
inconsistent value to be constructed (ie: insufficient number of
items added to a container with a specific number of children
required).  It is also an error to call this function if the builder
was created with an indefinite array or maybe type and no children
have been added; in this case it is impossible to infer the type of
the empty array.&lt;/doc&gt;

             line=&quot;3399&quot;&gt;Initialises a #GVariantBuilder structure.

@type must be non-%NULL.  It specifies the type of container to
construct.  It can be an indefinite type such as
%G_VARIANT_TYPE_ARRAY or a definite type such as &quot;as&quot; or &quot;(ii)&quot;.
Maybe, array, tuple, dictionary entry and variant-typed values may be
constructed.

After the builder is initialised, values are added using
g_variant_builder_add_value() or g_variant_builder_add().

After all the child values are added, g_variant_builder_end() frees
the memory associated with the builder and returns the #GVariant that
was created.

This function completely ignores the previous contents of @builder.
On one hand this means that it is valid to pass in completely
uninitialised memory.  On the other hand, this means that if you are
initialising over top of an existing #GVariantBuilder you need to
first call g_variant_builder_clear() in order to avoid leaking
memory.

You must not call g_variant_builder_ref() or
g_variant_builder_unref() on a #GVariantBuilder that was initialised
with this function.  If you ever pass a reference to a
#GVariantBuilder outside of the control of your own code then you
should assume that the person receiving that reference may try to use
reference counting; you should use g_variant_builder_new() instead of
this function.&lt;/doc&gt;

must include the tuple itself.

It can be used for doing a sequence of dictionary lookups in an
efficient way on an existing #GVariant dictionary or it can be used
to construct new dictionaries with a hashtable-like interface.  It
can also be used for taking existing dictionaries and modifying them
in order to create new ones.

#GVariantDict can only be used with %G_VARIANT_TYPE_VARDICT
dictionaries.

It is possible to use #GVariantDict allocated on the stack or on the
heap.  When using a stack-allocated #GVariantDict, you begin with a
call to g_variant_dict_init() and free the resources with a call to
g_variant_dict_clear().

Heap-allocated #GVariantDict follows normal refcounting rules: you
allocate it with g_variant_dict_new() and use g_variant_dict_ref()
and g_variant_dict_unref().

g_variant_dict_end() is used to convert the #GVariantDict back into a
dictionary-type #GVariant.  When used with stack-allocated instances,
this also implicitly frees all associated memory, but for
heap-allocated instances, you must still call g_variant_dict_unref()
afterwards.

You will typically want to use a heap-allocated #GVariantDict when
you expose it as part of an API.  For most other uses, the
stack-allocated form will be more convenient.

Consider the following two examples that do the same thing in each
style: take an existing dictionary and look up the &quot;count&quot; uint32
key, adding 1 to it if it is found, or returning an error if the
key is not found.  Each returns the new dictionary as a floating
#GVariant.

any other call.

In some cases it may be easier to place a #GVariantDict directly on
the stack of the calling function and initialise it with
g_variant_dict_init().  This is particularly useful when you are
using #GVariantDict to construct a #GVariant.&lt;/doc&gt;

It typically only makes sense to do this on a stack-allocated

through.  This function need not be called if you call
g_variant_dict_end() and it also doesn&#039;t need to be called on dicts
allocated with g_variant_dict_new (see g_variant_dict_unref() for
that).

It is valid to call this function on either an initialised
#GVariantDict or one that was previously cleared by an earlier call
to g_variant_dict_clear() but it is not valid to call this function
on uninitialised memory.&lt;/doc&gt;

If @from_asv is given, it is used to initialise the dictionary.

This function completely ignores the previous contents of @dict.  On
one hand this means that it is valid to pass in completely
uninitialised memory.  On the other hand, this means that if you are
initialising over top of an existing #GVariantDict you need to first
call g_variant_dict_clear() in order to avoid leaking memory.

You must not call g_variant_dict_ref() or g_variant_dict_unref() on a
#GVariantDict that was initialised with this function.  If you ever
pass a reference to a #GVariantDict outside of the control of your
own code then you should assume that the person receiving that
reference may try to use reference counting; you should use
g_variant_dict_new() instead of this function.&lt;/doc&gt;

g_variant_get().  In the case that %NULL would have been returned,
this function returns %FALSE and does not modify the values of the arguments
passed in to @....  Otherwise, it unpacks the returned
value and returns %TRUE.

@format_string determines the C types that are used for unpacking the
values and also determines if the values are copied or borrowed, see the

             line=&quot;5763&quot;&gt;Gets the next item in the container and unpacks it into the variable
argument list according to @format_string, returning %TRUE.

If no more items remain then %FALSE is returned.

On the first call to this function, the pointers appearing on the
variable argument list are assumed to point at uninitialised memory.
On the second and later calls, it is assumed that the same pointers
will be given and that they will point to the memory as set by the
previous call to this function.  This allows the previous values to
be freed, as appropriate.

This function is intended to be used with a while loop as
demonstrated in the following example.  This function can only be
used when iterating over an array.  It is only valid to call this
function with a string constant for the format string and the same
string constant must be used each time.  Mixing calls to this
function and g_variant_iter_next() or g_variant_iter_next_value() on
the same iterator causes undefined behavior.

If you break out of a such a while loop using g_variant_iter_loop() then
you must free or unreference all the unpacked values as you would with
g_variant_get(). Failure to do so will cause a memory leak.

Here is an example for memory management with g_variant_iter_loop():
|[&amp;lt;!-- language=&quot;C&quot; --&amp;gt;
  // Iterates a dictionary of type &#039;a{sv}&#039;
  void
  iterate_dictionary (GVariant *dictionary)
  {
    GVariantIter iter;
    GVariant *value;
    gchar *key;

    g_variant_iter_init (&amp;amp;iter, dictionary);
    while (g_variant_iter_loop (&amp;amp;iter, &quot;{sv}&quot;, &amp;amp;key, &amp;amp;value))
      {
        g_print (&quot;Item &#039;%s&#039; has type &#039;%s&#039;\n&quot;, key,
                 g_variant_get_type_string (value));

        // no need to free &#039;key&#039; and &#039;value&#039; here
        // unless breaking out of this loop
      }
  }
]|

For most cases you should use g_variant_iter_next().

This function is really only useful when unpacking into #GVariant or
#GVariantIter in order to allow you to skip the call to
g_variant_unref() or g_variant_iter_free().

For example, if you are only looping over simple integer and string
types, g_variant_iter_next() is definitely preferred.  For string
types, use the &#039;&amp;amp;&#039; prefix to avoid allocating any memory at all (and
thereby avoiding the need to free anything as well).

@format_string determines the C types that are used for unpacking
the values and also determines if the values are copied or borrowed.

[`GVariant` format strings](gvariant-format-strings.html#pointers).&lt;/doc&gt;

If no more items remain then %FALSE is returned.

All of the pointers given on the variable arguments list of this
function are assumed to point at uninitialised memory.  It is the
responsibility of the caller to free all of the values returned by
the unpacking process.

Here is an example for memory management with g_variant_iter_next():
|[&amp;lt;!-- language=&quot;C&quot; --&amp;gt;
  // Iterates a dictionary of type &#039;a{sv}&#039;
  void
  iterate_dictionary (GVariant *dictionary)
  {
    GVariantIter iter;
    GVariant *value;
    gchar *key;

    g_variant_iter_init (&amp;amp;iter, dictionary);
    while (g_variant_iter_next (&amp;amp;iter, &quot;{sv}&quot;, &amp;amp;key, &amp;amp;value))
      {
        g_print (&quot;Item &#039;%s&#039; has type &#039;%s&#039;\n&quot;, key,
                 g_variant_get_type_string (value));

        // must free data for ourselves
        g_variant_unref (value);
        g_free (key);
      }
  }
]|

For a solution that is likely to be more convenient to C programmers
when dealing with loops, see g_variant_iter_loop().

@format_string determines the C types that are used for unpacking
the values and also determines if the values are copied or borrowed.

you no longer need it.

           line=&quot;34&quot;&gt;A type in the [type@GLib.Variant] type system.

This section introduces the [type@GLib.Variant] type system. It is based, in
large part, on the D-Bus type system, with two major changes and
some minor lifting of restrictions. The
[D-Bus specification](http://dbus.freedesktop.org/doc/dbus-specification.html),
therefore, provides a significant amount of
information that is useful when working with [type@GLib.Variant].

The first major change with respect to the D-Bus type system is the
introduction of maybe (or ‘nullable’) types.  Any type in [type@GLib.Variant]
can be converted to a maybe type, in which case, `nothing` (or `null`)
becomes a valid value.  Maybe types have been added by introducing the
character `m` to type strings.

The second major change is that the [type@GLib.Variant] type system supports
the concept of ‘indefinite types’ — types that are less specific than
the normal types found in D-Bus.  For example, it is possible to speak
of ‘an array of any type’ in [type@GLib.Variant], where the D-Bus type system
would require you to speak of ‘an array of integers’ or ‘an array of
strings’.  Indefinite types have been added by introducing the
characters `*`, `?` and `r` to type strings.

Finally, all arbitrary restrictions relating to the complexity of
types are lifted along with the restriction that dictionary entries
may only appear nested inside of arrays.

Just as in D-Bus, [type@GLib.Variant] types are described with strings (‘type
strings’).  Subject to the differences mentioned above, these strings
are of the same form as those found in D-Bus.  Note, however: D-Bus
always works in terms of messages and therefore individual type
strings appear nowhere in its interface.  Instead, ‘signatures’
are a concatenation of the strings of the type of each argument in a
message.  [type@GLib.Variant] deals with single values directly so
[type@GLib.Variant] type strings always describe the type of exactly one
value.  This means that a D-Bus signature string is generally not a valid
[type@GLib.Variant] type string — except in the case that it is the signature
of a message containing exactly one argument.

An indefinite type is similar in spirit to what may be called an
abstract type in other type systems.  No value can exist that has an
indefinite type as its type, but values can exist that have types
that are subtypes of indefinite types.  That is to say,
[method@GLib.Variant.get_type] will never return an indefinite type, but
calling [method@GLib.Variant.is_of_type] with an indefinite type may return
true.  For example, you cannot have a value that represents ‘an
array of no particular type’, but you can have an ‘array of integers’
which certainly matches the type of ‘an array of no particular type’,
since ‘array of integers’ is a subtype of ‘array of no particular
type’.

This is similar to how instances of abstract classes may not
directly exist in other type systems, but instances of their
non-abstract subtypes may.  For example, in GTK, no object that has
the type of [`GtkWidget`](https://docs.gtk.org/gtk4/class.Widget.html) can
exist (since `GtkWidget` is an abstract class), but a [`GtkWindow`](https://docs.gtk.org/gtk4/class.Window.html)
can certainly be instantiated, and you would say that a `GtkWindow` is a
`GtkWidget` (since `GtkWindow` is a subclass of `GtkWidget`).

Two types may not be compared by value; use [method@GLib.VariantType.equal]
or [method@GLib.VariantType.is_subtype_of]  May be copied using
[method@GLib.VariantType.copy] and freed using [method@GLib.VariantType.free].

## GVariant Type Strings

A [type@GLib.Variant] type string can be any of the following:

- any basic type string (listed below)
- `v`, `r` or `*`
- one of the characters `a` or `m`, followed by another type string
- the character `(`, followed by a concatenation of zero or more other
  type strings, followed by the character `)`
- the character `{`, followed by a basic type string (see below),
  followed by another type string, followed by the character `}`

A basic type string describes a basic type (as per
[method@GLib.VariantType.is_basic]) and is always a single character in
length. The valid basic type strings are `b`, `y`, `n`, `q`, `i`, `u`, `x`,
`t`, `h`, `d`, `s`, `o`, `g` and `?`.

The above definition is recursive to arbitrary depth. `aaaaai` and
`(ui(nq((y)))s)` are both valid type strings, as is
`a(aa(ui)(qna{ya(yd)}))`. In order to not hit memory limits,
[type@GLib.Variant] imposes a limit on recursion depth of 65 nested
containers. This is the limit in the D-Bus specification (64) plus one to
allow a [`GDBusMessage`](../gio/class.DBusMessage.html) to be nested in
a top-level tuple.

The meaning of each of the characters is as follows:

- `b`: the type string of `G_VARIANT_TYPE_BOOLEAN`; a boolean value.
- `y`: the type string of `G_VARIANT_TYPE_BYTE`; a byte.
- `n`: the type string of `G_VARIANT_TYPE_INT16`; a signed 16 bit integer.
- `q`: the type string of `G_VARIANT_TYPE_UINT16`; an unsigned 16 bit integer.
- `i`: the type string of `G_VARIANT_TYPE_INT32`; a signed 32 bit integer.
- `u`: the type string of `G_VARIANT_TYPE_UINT32`; an unsigned 32 bit integer.
- `x`: the type string of `G_VARIANT_TYPE_INT64`; a signed 64 bit integer.
- `t`: the type string of `G_VARIANT_TYPE_UINT64`; an unsigned 64 bit integer.
- `h`: the type string of `G_VARIANT_TYPE_HANDLE`; a signed 32 bit value
  that, by convention, is used as an index into an array of file
  descriptors that are sent alongside a D-Bus message.
- `d`: the type string of `G_VARIANT_TYPE_DOUBLE`; a double precision
  floating point value.
- `s`: the type string of `G_VARIANT_TYPE_STRING`; a string.
- `o`: the type string of `G_VARIANT_TYPE_OBJECT_PATH`; a string in the form
  of a D-Bus object path.
- `g`: the type string of `G_VARIANT_TYPE_SIGNATURE`; a string in the form of
  a D-Bus type signature.
- `?`: the type string of `G_VARIANT_TYPE_BASIC`; an indefinite type that
  is a supertype of any of the basic types.
- `v`: the type string of `G_VARIANT_TYPE_VARIANT`; a container type that
  contain any other type of value.
- `a`: used as a prefix on another type string to mean an array of that
  type; the type string `ai`, for example, is the type of an array of
  signed 32-bit integers.
- `m`: used as a prefix on another type string to mean a ‘maybe’, or
  ‘nullable’, version of that type; the type string `ms`, for example,
  is the type of a value that maybe contains a string, or maybe contains
  nothing.
- `()`: used to enclose zero or more other concatenated type strings to
  create a tuple type; the type string `(is)`, for example, is the type of
  a pair of an integer and a string.
- `r`: the type string of `G_VARIANT_TYPE_TUPLE`; an indefinite type that is
  a supertype of any tuple type, regardless of the number of items.
- `{}`: used to enclose a basic type string concatenated with another type
  string to create a dictionary entry type, which usually appears inside of
  an array to form a dictionary; the type string `a{sd}`, for example, is
  the type of a dictionary that maps strings to double precision floating
  point values.

  The first type (the basic type) is the key type and the second type is
  the value type. The reason that the first type is restricted to being a
  basic type is so that it can easily be hashed.
- `*`: the type string of `G_VARIANT_TYPE_ANY`; the indefinite type that is
  a supertype of all types.  Note that, as with all type strings, this
  character represents exactly one type. It cannot be used inside of tuples
  to mean ‘any number of items’.

Any type string of a container that contains an indefinite type is,
itself, an indefinite type. For example, the type string `a*`
(corresponding to `G_VARIANT_TYPE_ARRAY`) is an indefinite type
that is a supertype of every array type. `(*s)` is a supertype
of all tuples that contain exactly two items where the second
item is a string.

`a{?*}` is an indefinite type that is a supertype of all arrays
containing dictionary entries where the key is any basic type and
the value is any type at all.  This is, by definition, a dictionary,
so this type string corresponds to `G_VARIANT_TYPE_DICTIONARY`. Note
that, due to the restriction that the key of a dictionary entry must
be a basic type, `{**}` is not a valid type string.&lt;/doc&gt;

Only returns %TRUE if the types are exactly equal.  Even if one type
is an indefinite type and the other is a subtype of it, %FALSE will
be returned if they are not exactly equal.  If you want to check for
subtypes, use g_variant_type_is_subtype_of().

%G_VARIANT_TYPE_TUPLE.

In the case of a dictionary entry type, this returns the type of
the key.

%NULL is returned in case of @type being %G_VARIANT_TYPE_UNIT.

This call, together with g_variant_type_next() provides an iterator
interface over tuple and dictionary entry types.&lt;/doc&gt;

A type is definite if its type string does not contain any indefinite
type characters (&#039;*&#039;, &#039;?&#039;, or &#039;r&#039;).

A #GVariant instance may not have an indefinite type, so calling
this function on the result of g_variant_get_type() will always
result in %TRUE being returned.  Calling this function on an
indefinite type like %G_VARIANT_TYPE_ARRAY, however, will result in
%FALSE being returned.&lt;/doc&gt;

@type must be the result of a previous call to
g_variant_type_first() or g_variant_type_next().

If called on the key type of a dictionary entry then this call
returns the value type.  If called on the value type of a dictionary
entry then this call returns %NULL.

For tuples, %NULL is returned when @type is the last item in a tuple.&lt;/doc&gt;

FAT-style READONLY attribute, and does not look at the ACL of a
file at all. This function is this in practise almost useless on
Windows. Software that needs to handle file permissions on Windows
more exactly should use the Win32 API.

           line=&quot;63&quot;&gt;Allocates @size bytes on the stack; these bytes will be freed when the current
stack frame is cleaned up. This macro essentially just wraps the alloca()
function present on most UNIX variants.
Thus it provides the same advantages and pitfalls as alloca():

- alloca() is very fast, as on most systems it&#039;s implemented by just adjusting
  the stack pointer register.

- It doesn&#039;t cause any memory fragmentation, within its scope, separate alloca()
  blocks just build up and are released together at function end.

- Allocation sizes have to fit into the current stack frame. For instance in a
  threaded environment on Linux, the per-thread stack size is limited to 2 Megabytes,
  so be sparse with alloca() uses.

- Allocation failure due to insufficient stack space is not indicated with a %NULL
  return like e.g. with malloc(). Instead, most systems probably handle it the same
  way as out of stack space situations from infinite function recursion, i.e.
  with a segmentation fault.

- Allowing @size to be specified by an untrusted party would allow for them
  to trigger a segmentation fault by specifying a large size, leading to a
  denial of service vulnerability. @size must always be entirely under the
  control of the program.

- Special care has to be taken when mixing alloca() with GNU C variable sized arrays.
  Stack space allocated with alloca() in the same scope as a variable sized array

value is cast to the given type. This is the main way to read or write an
element in a #GArray.

Writing an element is typically done by reference, as in the following
example. This example gets a pointer to an element in a #GArray, and then
writes to a field in it:
|[&amp;lt;!-- language=&quot;C&quot; --&amp;gt;
  EDayViewEvent *event;
  // This gets a pointer to the 4th element in the array of
  // EDayViewEvent structs.
  event = &amp;amp;g_array_index (events, EDayViewEvent, 3);
  event-&amp;gt;start_time = g_get_current_time ();
]|

This example reads from and writes to an array of integers:
|[&amp;lt;!-- language=&quot;C&quot; --&amp;gt;
  g_autoptr(GArray) int_array = g_array_new (FALSE, FALSE, sizeof (guint));
  for (guint i = 0; i &amp;lt; 10; i++)
    g_array_append_val (int_array, i);

  guint *my_int = &amp;amp;g_array_index (int_array, guint, 1);
  g_print (&quot;Int at index 1 is %u; decrementing it\n&quot;, *my_int);
  *my_int = *my_int - 1;

represent themselves. This includes UTF-8 and the ISO-8859-*
charsets, but not for instance double-byte encodings like the
Windows Codepage 932, where the trailing bytes of double-byte
characters include all ASCII letters. If you compare two CP932
strings using this function, you will get false matches.

           line=&quot;3283&quot;&gt;A convenience function for converting a string to a signed number.

This function assumes that @str contains only a number of the given
@base that is within inclusive bounds limited by @min and @max. If
this is true, then the converted number is stored in @out_num. An
empty string is not a valid input. A string with leading or
trailing whitespace is also an invalid input.

@base can be between 2 and 36 inclusive. Hexadecimal numbers must
not be prefixed with &quot;0x&quot; or &quot;0X&quot;. Such a problem does not exist
for octal numbers, since they were usually prefixed with a zero
which does not change the value of the parsed number.

Parsing failures result in an error with the `G_NUMBER_PARSER_ERROR`
domain. If the input is invalid, the error code will be
[error@GLib.NumberParserError.INVALID]. If the parsed number is out of
bounds - [error@GLib.NumberParserError.OUT_OF_BOUNDS].

parsing a string which starts with a number, but then has other
characters.&lt;/doc&gt;

This function behaves like the standard `strtod()` function
does in the C locale. It does this without actually changing
the current locale, since that would not be thread-safe.
A limitation of the implementation is that this function
will still accept localized versions of infinities and NANs.

This function is typically used when reading configuration
files or other non-user input that should be locale independent.
To handle input from the user you should normally use the
locale-sensitive system `strtod()` function.

To convert from a gdouble to a string in a locale-insensitive
way, use [func@GLib.ascii_dtostr].

If the correct value would cause overflow, plus or minus `HUGE_VAL`
is returned (according to the sign of the value), and `ERANGE` is
stored in `errno`. If the correct value would cause underflow,
zero is returned and `ERANGE` is stored in `errno`.

This function resets `errno` before calling `strtod()` so that
you can reliably detect overflow and underflow.&lt;/doc&gt;

This function behaves like the standard `strtoull()` function

changing the current locale, since that would not be
thread-safe.

Note that input with a leading minus sign (`-`) is accepted, and will return
the negation of the parsed number, unless that would overflow a `guint64`.
Critically, this means you cannot assume that a short fixed length input will
result in a low return value, as the input could have a leading `-`.

This function is typically used when reading configuration
files or other non-user input that should be locale independent.
To handle input from the user you should normally use the

`G_DISABLE_ASSERT` when compiling the application, so code must
not depend on any side effects from @expr. Similarly, it must not be used
in unit tests, otherwise the unit tests will be ineffective if compiled with
`G_DISABLE_ASSERT`. Use g_assert_true() and related macros in unit tests

           line=&quot;117&quot;&gt;Specifies a function to be called at normal program termination.

Since GLib 2.8.2, on Windows g_atexit() actually is a preprocessor
macro that maps to a call to the atexit() function in the C
library. This means that in case the code that calls g_atexit(),
i.e. atexit(), is in a DLL, the function will be called when the
DLL is detached from the program. This typically makes more sense
than that the function is called when the GLib DLL is detached,
which happened earlier when g_atexit() was a function in the GLib
DLL.

The behaviour of atexit() in the context of dynamically loaded
modules is not formally specified and varies wildly.

On POSIX systems, calling g_atexit() (or atexit()) in a dynamically
loaded module which is unloaded before the program terminates might
well cause a crash at program exit.

Some POSIX systems implement atexit() like Windows, and have each
dynamically loaded module maintain an own atexit chain that is
called when the module is unloaded.

On other POSIX systems, before a dynamically loaded module is
unloaded, the registered atexit functions (if any) residing in that
module are called, regardless where the code that registered them
resided. This is presumably the most robust approach.

As can be seen from the above, for portability it&#039;s best to avoid
calling g_atexit() (or atexit()) except in the main executable of a
program.&lt;/doc&gt;
      &lt;doc-deprecated xml:space=&quot;preserve&quot;&gt;It is best to avoid g_atexit().&lt;/doc-deprecated&gt;

           line=&quot;37&quot;&gt;Incrementally encode a sequence of binary data into its Base-64 stringified
representation. By calling this function multiple times you can convert
data in chunks to avoid having to have the full encoded data in memory.

When all of the data has been converted you must call
g_base64_encode_close() to flush the saved state.

The output buffer must be large enough to fit all the data that will
be written to it. Due to the way base64 encodes you will need
at least: (@len / 3 + 1) * 4 + 4 bytes (+ 4 may be needed in case of
non-zero state). If you enable line-breaking you will need at least:
((@len / 3 + 1) * 4 + 4) / 76 + 1 bytes of extra space.

@break_lines is typically used when putting base64-encoded data in emails.
It breaks the lines at 76 columns instead of putting all of the text on
the same line. This avoids problems with long lines in the email system.
Note however that it breaks the lines with `LF` characters, not
`CR LF` sequences, so the result cannot be passed directly to SMTP
or certain other protocols.&lt;/doc&gt;

artifact and the argument passed to it should not be `volatile`.&lt;/doc&gt;

separator for the current platform.

On Unix, this function behaves identically to `g_build_path
(G_DIR_SEPARATOR_S, first_element, ....)`.

On Windows, it takes into account that either the backslash
(`\` or slash (`/`) can be used as separator in filenames, but
otherwise behaves as on UNIX. When file pathname separators need
to be inserted, the one that last previously occurred in the
parameters (reading from left to right) is used.

No attempt is made to force the resulting filename to be an absolute
path. If the first element is a relative path, the result will
be a relative path.

If you are building a path programmatically you may want to use
#GPathBuf instead.&lt;/doc&gt;

           line=&quot;2029&quot;&gt;Creates a path from a series of elements using @separator as the
separator between elements.

At the boundary between two elements, any trailing occurrences of
separator in the first element, or leading occurrences of separator
in the second element are removed and exactly one copy of the
separator is inserted.

Empty elements are ignored.

The number of leading copies of the separator on the result is
the same as the number of leading copies of the separator on
the first non-empty element.

The number of trailing copies of the separator on the result is
the same as the number of trailing copies of the separator on
the last non-empty element. (Determination of the number of
trailing copies is done without stripping leading copies, so
if the separator is `ABA`, then `ABABA` has 1 trailing copy.)

However, if there is only a single non-empty element, and there
are no characters in that element not part of the leading or
trailing separators, then the result is exactly the original value
of that element.

Other than for determination of the number of leading and trailing
copies of the separator, elements consisting only of copies
of the separator are ignored.&lt;/doc&gt;

If two array elements compare equal, their order in the sorted array
is undefined. If you want equal elements to keep their order (i.e.
you want a stable sort) you can write a comparison function that,
if two elements would otherwise compare equal, compares them by
their addresses.&lt;/doc&gt;

was compiled against.

Compatibility is defined by two things: first the version
of the running library is newer than the version
`@required_major.required_minor.@required_micro`. Second
the running library must be binary compatible with the
version `@required_major.@required_minor.@required_micro`

If you obtain @pid from g_spawn_async() or g_spawn_async_with_pipes()
you will need to pass %G_SPAWN_DO_NOT_REAP_CHILD as flag to
the spawn function for the child watching to work.

Note that on platforms where #GPid must be explicitly closed
(see g_spawn_close_pid()) @pid must not be closed while the
source is still active. Typically, you will want to call
g_spawn_close_pid() in the callback function for the source.

GLib supports only a single callback per process id.
On POSIX platforms, the same restrictions mentioned for
g_child_watch_source_new() apply to this function.

This internally creates a main loop source using
g_child_watch_source_new() and attaches it to the main loop context
using g_source_attach(). You can do these steps manually if you
need greater control.&lt;/doc&gt;

           line=&quot;6002&quot;&gt;Sets a function to be called when the child indicated by @pid
exits, at the priority @priority.

If you obtain @pid from g_spawn_async() or g_spawn_async_with_pipes()
you will need to pass %G_SPAWN_DO_NOT_REAP_CHILD as flag to
the spawn function for the child watching to work.

In many programs, you will want to call g_spawn_check_wait_status()
in the callback to determine whether or not the child exited
successfully.

Also, note that on platforms where #GPid must be explicitly closed
(see g_spawn_close_pid()) @pid must not be closed while the source
is still active.  Typically, you should invoke g_spawn_close_pid()
in the callback function for the source.

GLib supports only a single callback per process id.
On POSIX platforms, the same restrictions mentioned for
g_child_watch_source_new() apply to this function.

This internally creates a main loop source using
g_child_watch_source_new() and attaches it to the main loop context
using g_source_attach(). You can do these steps manually if you
need greater control.&lt;/doc&gt;

           line=&quot;5886&quot;&gt;Creates a new child_watch source.

The source will not initially be associated with any #GMainContext
and must be added to one with g_source_attach() before it will be
executed.

Note that child watch sources can only be used in conjunction with
`g_spawn...` when the %G_SPAWN_DO_NOT_REAP_CHILD flag is used.

Note that on platforms where #GPid must be explicitly closed
(see g_spawn_close_pid()) @pid must not be closed while the
source is still active. Typically, you will want to call
g_spawn_close_pid() in the callback function for the source.

On POSIX platforms, the following restrictions apply to this API
due to limitations in POSIX process interfaces:

* @pid must be a child of this process
* @pid must be positive
* the application must not call `waitpid` with a non-positive
  first argument, for instance in another thread
* the application must not wait for @pid to exit by any other
  mechanism, including `waitpid(pid, ...)` or a second child-watch
  source for the same @pid
* the application must not ignore `SIGCHLD`
* Before 2.78, the application could not send a signal (`kill()`) to the
  watched @pid in a race free manner. Since 2.78, you can do that while the
  associated #GMainContext is acquired.
* Before 2.78, even after destroying the #GSource, you could not
  be sure that @pid wasn&#039;t already reaped. Hence, it was also not
  safe to `kill()` or `waitpid()` on the process ID after the child watch
  source was gone. Destroying the source before it fired made it
  impossible to reliably reap the process.

If any of those conditions are not met, this and related APIs will
not work correctly. This can often be diagnosed via a GLib warning
stating that `ECHILD` was received by `waitpid`.

Calling `waitpid` for specific processes other than @pid remains a
valid thing to do.&lt;/doc&gt;

On Windows the file protection mechanism is not at all POSIX-like,
and the underlying chmod() function in the C library just sets or
clears the FAT-style READONLY attribute. It does not touch any
ACL. Software that needs to manage file permissions on Windows
exactly should use the Win32 API.

See your C library manual for more details about chmod().&lt;/doc&gt;

           line=&quot;1747&quot;&gt;This wraps the close() call. In case of error, %errno will be
preserved, but the error will also be stored as a #GError in @error.
In case of success, %errno is undefined.

Besides using #GError, there is another major reason to prefer this
function over the call provided by the system; on Unix, it will
attempt to correctly handle %EINTR, which has platform-specific
semantics.

It is a bug to call this function with an invalid file descriptor.

On POSIX platforms since GLib 2.76, this function is async-signal safe
if (and only if) @error is %NULL and @fd is a valid open file descriptor.
This makes it safe to call from a signal handler or a #GSpawnChildSetupFunc
under those conditions.
See [`signal(7)`](man:signal(7)) and
[`signal-safety(7)`](man:signal-safety(7)) for more details.&lt;/doc&gt;

           line=&quot;849&quot;&gt;Close every file descriptor equal to or greater than @lowfd.

Typically @lowfd will be 3, to leave standard input, standard output
and standard error open.

This is the same as Linux `close_range (lowfd, ~0U, 0)`,
but portable to other OSs and to older versions of Linux.
Equivalently, it is the same as BSD `closefrom (lowfd)`, but portable,
and async-signal-safe on all OSs.

This function is async-signal safe, making it safe to call from a
signal handler or a [callback@GLib.SpawnChildSetupFunc], as long as @lowfd is
non-negative.

specification, which leaves this behaviour implementation defined. Note that
this is the same error code as is returned for an invalid byte sequence in
the input character set. To get defined behaviour for conversion of
unrepresentable characters, use g_convert_with_fallback().&lt;/doc&gt;

           line=&quot;1081&quot;&gt;A wrapper for the POSIX creat() function. The creat() function is
used to convert a pathname into a file descriptor, creating a file
if necessary.

On POSIX systems file descriptors are implemented by the operating
system. On Windows, it&#039;s the C library that implements creat() and
file descriptors. The actual Windows API for opening files is
different, see MSDN documentation for CreateFile(). The Win32 API
uses file handles, which are more randomish integers, not small
integers like file descriptors.

Because file descriptors are specific to the C library on Windows,
the file descriptor returned by this function makes sense only to
functions in the same C library. Thus if the GLib-using code uses a
different C library than GLib does, the file descriptor returned by
this function cannot be passed to C library functions like write()
or read().

See your C library manual for more details about creat().&lt;/doc&gt;

           line=&quot;237&quot;&gt;Logs a ‘critical warning’ ([flags@GLib.LogLevelFlags.LEVEL_CRITICAL]).

Critical warnings are intended to be used in the event of an error
that originated in the current process (a programmer error).
Logging of a critical error is by definition an indication of a bug
somewhere in the current program (or its libraries).

[func@GLib.return_if_fail], [func@GLib.return_val_if_fail], [func@GLib.return_if_reached] and
[func@GLib.return_val_if_reached] log at [flags@GLib.LogLevelFlags.LEVEL_CRITICAL].

You can make critical warnings fatal at runtime by
setting the `G_DEBUG` environment variable (see
[Running GLib Applications](glib-running.html)):

```
G_DEBUG=fatal-warnings gdb ./my-program
```

You can also use [func@GLib.log_set_always_fatal].

Any unrelated failures can be skipped over in
[gdb](https://www.gnu.org/software/gdb/) using the `continue` command.

The message should typically *not* be translated to the
user’s language.

If [func@GLib.log_default_handler] is used as the log handler function, a new-line
character will automatically be appended to @..., and need not be entered
manually.

If structured logging is enabled, this will use [func@GLib.log_structured];
otherwise it will use [func@GLib.log]. See
[Using Structured Logging](logging.html#using-structured-logging).&lt;/doc&gt;

Works just like the platform&#039;s C library strftime() function,
but only accepts date-related formats; time-related formats
give undefined results. Date must be valid. Unlike strftime()
(which uses the locale encoding), works on a UTF-8 format
string and stores a UTF-8 result.

This function does not provide any conversion specifiers in
addition to those implemented by the platform&#039;s C library.
For example, don&#039;t expect that using g_date_strftime() would
make the \%F provided by the C99 strftime() work on Windows
where the C library only complies to C89.&lt;/doc&gt;

The message should typically *not* be translated to the user’s language.

If [func@GLib.log_default_handler] is used as the log handler function, a new-line
character will automatically be appended to @..., and need not be entered
manually.

Such messages are suppressed by the [func@GLib.log_default_handler] and
[func@GLib.log_writer_default] unless the `G_MESSAGES_DEBUG` environment variable is
set appropriately. If you need to set the allowed domains at runtime, use
[func@GLib.log_writer_default_set_debug_domains].

If structured logging is enabled, this will use [func@GLib.log_structured];
otherwise it will use [func@GLib.log]. See
[Using Structured Logging](logging.html#using-structured-logging).&lt;/doc&gt;

           filename=&quot;glib/ggettext.c&quot;
           line=&quot;354&quot;&gt;This function is a wrapper of dgettext() which does not translate
the message if the default domain as set with textdomain() has no
translations for the current locale.

The advantage of using this function over dgettext() proper is that
libraries using this function (like GTK) will not use translations
if the application using the library does not have translations for
the current locale.  This results in a consistent English-only
interface instead of one having partial translations.  For this
feature to work, the call to textdomain() and setlocale() should
precede any g_dgettext() invocations.  For GTK, it means calling
textdomain() before gtk_init or its variants.

This function disables translations if and only if upon its first
call all the following conditions hold:

- @domain is not %NULL

- textdomain() has been called to set a default text domain

- there is no translations available for the default text domain
  and the current locale

- current locale is not &quot;C&quot; or any English locales (those
  starting with &quot;en_&quot;)

Note that this behavior may not be desired for example if an application
has its untranslated messages in a language other than English. In those
cases the application should call textdomain() after initializing GTK.

Applications should normally not use this function directly,
but use the _() macro for translations.&lt;/doc&gt;

@tmpl should be a string in the GLib file name encoding containing
a sequence of six &#039;X&#039; characters, as the parameter to g_mkstemp().
However, unlike these functions, the template should only be a
basename, no directory components are allowed. If template is
%NULL, a default template is used.

Note that in contrast to g_mkdtemp() (and mkdtemp()) @tmpl is not
modified, and might thus be a read-only literal string.&lt;/doc&gt;

           line=&quot;277&quot;&gt;A convenience function/macro to log an error message.

The message should typically *not* be translated to the user’s language.

This is not intended for end user error reporting. Use of [type@GLib.Error] is
preferred for that instead, as it allows calling functions to perform actions
conditional on the type of error.

Error messages are always fatal, resulting in a call to [func@GLib.BREAKPOINT]
to terminate the application. This function will
result in a core dump; don’t use it for errors you expect.
Using this function indicates a bug in your program, i.e.
an assertion failure.

If [func@GLib.log_default_handler] is used as the log handler function, a new-line
character will automatically be appended to @..., and need not be entered
manually.

If structured logging is enabled, this will use [func@GLib.log_structured];
otherwise it will use [func@GLib.log]. See
[Using Structured Logging](logging.html#using-structured-logging).&lt;/doc&gt;

@error_type_name should not be freed. @error_type_private_size must
be greater than 0.

@error_type_init receives an initialized #GError and should then initialize
the private data.

@error_type_copy is a function that receives both original and a copy
#GError and should copy the fields of the private error data. The standard
#GError fields are already handled.

@error_type_clear receives the pointer to the error, and it should free the
fields of the private error data. It should not free the struct itself though.

Normally, it is better to use G_DEFINE_EXTENDED_ERROR(), as it
already takes care of passing valid information to this function.&lt;/doc&gt;

Typically @lowfd will be 3, to leave standard input, standard output

This is the same as Linux `close_range (lowfd, ~0U, CLOSE_RANGE_CLOEXEC)`,
but portable to other OSs and to older versions of Linux.

This function is async-signal safe, making it safe to call from a
signal handler or a [callback@GLib.SpawnChildSetupFunc], as long as @lowfd is
non-negative.

%FALSE and sets @error. The error domain is %G_FILE_ERROR. Possible error

@tmpl should be a string in the GLib file name encoding containing
a sequence of six &#039;X&#039; characters, as the parameter to g_mkstemp().
However, unlike these functions, the template should only be a
basename, no directory components are allowed. If template is
%NULL, a default template is used.

Note that in contrast to g_mkstemp() (and mkstemp()) @tmpl is not
modified, and might thus be a read-only literal string.

Upon success, and if @name_used is non-%NULL, the actual name used
is returned in @name_used. This string should be freed with g_free()
when not needed any longer. The returned name is in the GLib file
name encoding.&lt;/doc&gt;

           line=&quot;1259&quot;&gt;Writes all of @contents to a file named @filename, with good error checking.
If a file called @filename already exists it will be overwritten.

@flags control the properties of the write operation: whether it’s atomic,
and what the tradeoff is between returning quickly or being resilient to
system crashes.

As this function performs file I/O, it is recommended to not call it anywhere
where blocking would cause problems, such as in the main loop of a graphical
application. In particular, if @flags has any value other than
%G_FILE_SET_CONTENTS_NONE then this function may call `fsync()`.

If %G_FILE_SET_CONTENTS_CONSISTENT is set in @flags, the operation is atomic
in the sense that it is first written to a temporary file which is then
renamed to the final name.

Notes:

- On UNIX, if @filename already exists hard links to @filename will break.
  Also since the file is recreated, existing permissions, access control
  lists, metadata etc. may be lost. If @filename is a symbolic link,
  the link itself will be replaced, not the linked file.

- On UNIX, if @filename already exists and is non-empty, and if the system
  supports it (via a journalling filesystem or equivalent), and if
  %G_FILE_SET_CONTENTS_CONSISTENT is set in @flags, the `fsync()` call (or
  equivalent) will be used to ensure atomic replacement: @filename
  will contain either its old contents or @contents, even in the face of
  system power loss, the disk being unsafely removed, etc.

- On UNIX, if @filename does not already exist or is empty, there is a
  possibility that system power loss etc. after calling this function will
  leave @filename empty or full of NUL bytes, depending on the underlying
  filesystem, unless %G_FILE_SET_CONTENTS_DURABLE and
  %G_FILE_SET_CONTENTS_CONSISTENT are set in @flags.

- On Windows renaming a file will not remove an existing file with the
  new name, so on Windows there is a race condition between the existing
  file being removed and the temporary file being renamed.

- On Windows there is no way to remove a file that is open to some
  process, or mapped into memory. Thus, this function will fail if
  @filename already exists and is open.

If the call was successful, it returns %TRUE. If the call was not successful,
it returns %FALSE and sets @error. The error domain is %G_FILE_ERROR.
Possible error codes are those in the #GFileError enumeration.

Note that the name for the temporary file is constructed by appending up
to 7 characters to @filename.

If the file didn’t exist before and is created, it will be given the
permissions from @mode. Otherwise, the permissions of the existing file may
be changed to @mode depending on @flags, or they may remain unchanged.&lt;/doc&gt;

will return %TRUE if the file exists; the check whether it&#039;s a
directory doesn&#039;t matter since the existence test is %TRUE. With
the current set of available tests, there&#039;s no point passing in
more than one test at a time.

Apart from %G_FILE_TEST_IS_SYMLINK all tests follow symbolic links,
so for a symbolic link to a regular file g_file_test() will return
%TRUE for both %G_FILE_TEST_IS_SYMLINK and %G_FILE_TEST_IS_REGULAR.

Note, that for a dangling symbolic link g_file_test() will return
%TRUE for %G_FILE_TEST_IS_SYMLINK and %FALSE for all other flags.

You should never use g_file_test() to test whether it is safe
to perform an operation, because there is always the possibility
of the condition changing before you actually perform the operation,
see [TOCTOU](https://en.wikipedia.org/wiki/Time-of-check_to_time-of-use).

For example, you might think you could use %G_FILE_TEST_IS_SYMLINK
to know whether it is safe to write to a file without being
tricked into writing into a different location. It doesn&#039;t work!

|[&amp;lt;!-- language=&quot;C&quot; --&amp;gt;
 // DON&#039;T DO THIS
 if (!g_file_test (filename, G_FILE_TEST_IS_SYMLINK))
   {
     fd = g_open (filename, O_WRONLY);
     // write to fd
   }

 // DO THIS INSTEAD
 fd = g_open (filename, O_WRONLY | O_NOFOLLOW | O_CLOEXEC);
 if (fd == -1)
   {
     // check error
     if (errno == ELOOP)
       // file is a symlink and can be ignored
     else
       // handle errors as before
   }
 else
   {
     // write to fd
   }
]|

Another thing to note is that %G_FILE_TEST_EXISTS and
%G_FILE_TEST_IS_EXECUTABLE are implemented using the access()
system call. This usually doesn&#039;t matter, but if your program
is setuid or setgid it means that these tests will give you
the answer for the real user ID and group ID, rather than the
effective user ID and group ID.

On Windows, there are no symlinks, so testing for
%G_FILE_TEST_IS_SYMLINK will always return %FALSE. Testing for
%G_FILE_TEST_IS_EXECUTABLE will just check that the file exists and
its name indicates that it is executable, checking for well-known
extensions and those listed in the `PATHEXT` environment variable.&lt;/doc&gt;

can be translated in the display.

If GLib cannot make sense of the encoding of @filename, as a last resort it
replaces unknown characters with U+FFFD, the Unicode replacement character.
You can search the result for the UTF-8 encoding of this character (which is
&quot;\357\277\275&quot; in octal notation) to find out if @filename was in an invalid
encoding.

You must pass the whole absolute pathname to this functions so that
translation of well known locations can be done.

This function is preferred over g_filename_display_name() if you know the
whole path, as it allows translation.&lt;/doc&gt;

On Windows, if @program does not have a file type suffix, tries
with the suffixes .exe, .cmd, .bat and .com, and the suffixes in
the `PATHEXT` environment variable.

On Windows, it looks for the file in the same way as CreateProcess()
would. This means first in the directory where the executing
program was loaded from, then in the current directory, then in the
Windows 32-bit system directory, then in the Windows directory, and
finally in the directories in the `PATH` environment variable. If
the program is found, the return value contains the full name
including the type suffix.&lt;/doc&gt;

           filename=&quot;glib/gstdio.c&quot;
           line=&quot;1542&quot;&gt;A wrapper for the stdio `fopen()` function. The `fopen()` function
opens a file and associates a new stream with it.

Because file descriptors are specific to the C library on Windows,
and a file descriptor is part of the `FILE` struct, the `FILE*` returned
by this function makes sense only to functions in the same C library.
Thus if the GLib-using code uses a different C library than GLib does,
the FILE* returned by this function cannot be passed to C library
functions like `fprintf()` or `fread()`.

See your C library manual for more details about `fopen()`.

As `close()` and `fclose()` are part of the C library, this implies that it is
currently impossible to close a file if the application C library and the C library
used by GLib are different. Convenience functions like g_file_set_contents_full()
avoid this problem.&lt;/doc&gt;

size is known at compile time (see [documentation of

If @mem is %NULL this is a no-op (and @size is ignored).

It is an error if @size doesn’t match the size passed when @mem was
allocated. @size is passed to this function to allow optimizations in the
allocator. If you don’t know the allocation size, use g_free() instead.

In case a GCC compatible compiler is used, this function may be used
automatically via g_free() if the allocated size is known at compile time,

might use this character set as an argument to g_convert(), to convert
from the current locale&#039;s encoding to some other encoding. (Frequently
g_locale_to_utf8() and g_locale_from_utf8() are nice shortcuts, though.)

On Windows the character set returned by this function is the
so-called system default ANSI code-page. That is the character set
used by the &quot;narrow&quot; versions of C library and Win32 functions that
handle file names. It might be different from the character set
used by the C library&#039;s current locale.

On Linux, the character set is found by consulting nl_langinfo() if
available. If not, the environment variables `LC_ALL`, `LC_CTYPE`, `LANG`
and `CHARSET` are queried in order. nl_langinfo() returns the C locale if
no locale has been loaded by setlocale().

The return value is %TRUE if the locale&#039;s encoding is UTF-8, in that
case you can perhaps avoid calling g_convert().

which is suitable for printing output to the terminal.

Usually this matches the result returned by g_get_charset(), but in
environments where the locale&#039;s character set does not match the encoding
of the console this function tries to guess a more suitable value instead.

On Windows the character set returned by this function is the
output code page used by the console associated with the calling process.
If the codepage can&#039;t be determined (for example because there is no
console attached) UTF-8 is assumed.

The return value is %TRUE if the locale&#039;s encoding is UTF-8, in that

           line=&quot;1046&quot;&gt;Determines the preferred character sets used for filenames.
The first character set from the @charsets is the filename encoding, the
subsequent character sets are used when trying to generate a displayable
representation of a filename, see g_filename_display_name().

On Unix, the character sets are determined by consulting the
environment variables `G_FILENAME_ENCODING` and `G_BROKEN_FILENAMES`.
On Windows, the character set used in the GLib API is always UTF-8
and said environment variables have no effect.

`G_FILENAME_ENCODING` may be set to a comma-separated list of
character set names. The special token &quot;\@locale&quot; is taken
to  mean the character set for the [current locale][setlocale].
If `G_FILENAME_ENCODING` is not set, but `G_BROKEN_FILENAMES` is,
the character set of the current locale is taken as the filename
encoding. If neither environment variable  is set, UTF-8 is taken
as the filename encoding, but the character set of the current locale
is also put in the list of encodings.

The returned @charsets belong to GLib and must not be freed.

Note that on Unix, regardless of the locale character set or
`G_FILENAME_ENCODING` value, the actual file names present
on a system might be in any random encoding or just gibberish.&lt;/doc&gt;

           line=&quot;902&quot;&gt;Gets the current user&#039;s home directory.

As with most UNIX tools, this function will return the value of the
`HOME` environment variable if it is set to an existing absolute path
name, falling back to the `passwd` file in the case that it is unset.

If the path given in `HOME` is non-absolute, does not exist, or is
not a directory, the result is undefined.

Before version 2.36 this function would ignore the `HOME` environment
variable, taking the value from the `passwd` database instead. This was
changed to increase the compatibility of GLib with other programs (and
the XDG basedir specification) and to increase testability of programs
based on GLib (by making it easier to run them from test frameworks).

If your program has a strong requirement for either the new or the
old behaviour (and if you don&#039;t wish to increase your GLib
dependency to ensure that the new behaviour is in effect) then you
should either directly check the `HOME` environment variable yourself
or unset it before calling any functions in GLib.&lt;/doc&gt;

The returned name is not necessarily a fully-qualified domain name,
or even present in DNS or some other name service at all. It need
not even be unique on your local network or site, but usually it
is. Callers should not rely on the return value having any specific
properties like uniqueness for security purposes. Even if the name
of the machine is changed while an application is running, the
return value from this function does not change. The returned
string is owned by GLib and should not be modified or freed. If no
name can be determined, a default fixed string &quot;localhost&quot; is
returned.

e.g. construct locale-dependent filenames or search paths. The returned
list is sorted from most desirable to least desirable.
This function handles territory, charset and extra locale modifiers. See
[`setlocale(3)`](man:setlocale) for information about locales and their format.

@locale itself is guaranteed to be returned in the output.

For example, if @locale is `fr_BE`, then the returned list
is `fr_BE`, `fr`. If @locale is `en_GB.UTF-8@euro`, then the returned list
is `en_GB.UTF-8@euro`, `en_GB.UTF-8`, `en_GB@euro`, `en_GB`, `en.UTF-8@euro`,
`en.UTF-8`, `en@euro`, `en`.

If you need the list of variants for the current locale,
use g_get_language_names().&lt;/doc&gt;

The monotonic clock will always increase and doesn&#039;t suffer
discontinuities when the user (or NTP) changes the system time.  It
may or may not continue to tick during times where the machine is
suspended.

We try to use the clock that corresponds as closely as possible to
the passage of time as measured by system calls such as poll() but it
may not always be possible to do this.&lt;/doc&gt;

in contrast to g_get_application_name().

If you are using #GApplication the program name is set in
g_application_run(). In case of GDK or GTK it is set in
gdk_init(), which is called by gtk_init() and the
#GtkApplication::startup handler. The program name is found by

This call is functionally equivalent to g_get_current_time() except
that the return value is often more convenient than dealing with a
#GTimeVal.

You should only use this call if you are actually interested in the real
wall-clock time.  g_get_monotonic_time() is probably more useful for

On UNIX platforms this is determined using the mechanisms described
in the
[XDG Base Directory Specification](http://www.freedesktop.org/Standards/basedir-spec).
In this case the list of directories retrieved will be `XDG_CONFIG_DIRS`.

On Windows it follows XDG Base Directory Specification if `XDG_CONFIG_DIRS` is defined.
If `XDG_CONFIG_DIRS` is undefined, the directory that contains application
data for all users is used instead. A typical path is
`C:\Documents and Settings\All Users\Application Data`.
This folder is used for application data
that is not user specific. For example, an application can store
a spell-check dictionary, a database of clip art, or a log file in the
FOLDERID_ProgramData folder. This information will not roam and is available
to anyone using the computer.

system-wide application data.

On UNIX platforms this is determined using the mechanisms described
in the
[XDG Base Directory Specification](http://www.freedesktop.org/Standards/basedir-spec)
In this case the list of directories retrieved will be `XDG_DATA_DIRS`.

On Windows it follows XDG Base Directory Specification if `XDG_DATA_DIRS` is defined.
If `XDG_DATA_DIRS` is undefined,
the first elements in the list are the Application Data
and Documents folders for All Users. (These can be determined only
on Windows 2000 or later and are not present in the list on other
Windows versions.) See documentation for FOLDERID_ProgramData and
FOLDERID_PublicDocuments.

Then follows the &quot;share&quot; subfolder in the installation folder for
the package containing the DLL that calls this function, if it can
be determined.

Finally the list contains the &quot;share&quot; subfolder in the installation
folder for GLib, and in the installation folder for the package the
application&#039;s .exe file belongs to.

The installation folders above are determined by looking up the
folder where the module (DLL or EXE) in question is located. If the
folder&#039;s name is &quot;bin&quot;, its parent is used, otherwise the folder
itself.

Note that on Windows the returned list can vary depending on where
this function is called.

           filename=&quot;glib/gutils.c&quot;
           line=&quot;955&quot;&gt;Gets the directory to use for temporary files.

On UNIX, this is taken from the `TMPDIR` environment variable.
If the variable is not set, `P_tmpdir` is
used, as defined by the system C library. Failing that, a
hard-coded default of &quot;/tmp&quot; is returned.

On Windows, the `TEMP` environment variable is used, with the
root directory of the Windows installation (eg: &quot;C:\&quot;) used
as a default.

The encoding of the returned string is system-defined. On Windows,
it is always UTF-8. The return value is never %NULL or the empty

In this case the directory retrieved will be `XDG_CACHE_HOME`.

On Windows it follows XDG Base Directory Specification if `XDG_CACHE_HOME` is defined.
If `XDG_CACHE_HOME` is undefined, the directory that serves as a common
repository for temporary Internet files is used instead. A typical path is
`C:\Documents and Settings\username\Local Settings\Temporary Internet Files`.

This is determined using the mechanisms described
in the
[XDG Base Directory Specification](http://www.freedesktop.org/Standards/basedir-spec).
This is the directory
specified in the `XDG_RUNTIME_DIR` environment variable.
In the case that this variable is not set, we return the value of
g_get_user_cache_dir(), after verifying that it exists.

The return value is cached and modifying it at runtime is not supported, as
it’s not thread-safe to modify environment variables at runtime.&lt;/doc&gt;

On UNIX this is done using the XDG special user directories.
For compatibility with existing practise, %G_USER_DIRECTORY_DESKTOP
falls back to `$HOME/Desktop` when XDG special user directories have
not been set up.

Depending on the platform, the user might be able to change the path
of the special directory without requiring the session to restart; GLib
will not reflect any change once the special directories are loaded.&lt;/doc&gt;

particular user.

On UNIX platforms this is determined using the mechanisms described
in the
[XDG Base Directory Specification](http://www.freedesktop.org/Standards/basedir-spec).
In this case the directory retrieved will be `XDG_STATE_HOME`.

On Windows it follows XDG Base Directory Specification if `XDG_STATE_HOME` is defined.
If `XDG_STATE_HOME` is undefined, the folder to use for local (as opposed
to roaming) application data is used instead. See the
[documentation for `FOLDERID_LocalAppData`](https://docs.microsoft.com/en-us/windows/win32/shell/knownfolderid).
Note that in this case on Windows it will be the same
as what g_get_user_data_dir() returns.

The return value is cached and modifying it at runtime is not supported, as
it’s not thread-safe to modify environment variables at runtime.&lt;/doc&gt;

is equivalent to calling g_hash_table_replace() with @key as both the
key and the value.

In particular, this means that if @key already exists in the hash table, then
the old copy of @key in the hash table is freed and @key replaces it in the
table.

When a hash table only ever contains keys that have themselves as the
corresponding value it is able to be stored more efficiently.  See
the discussion in the section description.

Starting from GLib 2.40, this function returns a boolean value to
indicate whether the newly added value was already in the hash table
or not.&lt;/doc&gt;

g_hash_table_find() or g_hash_table_foreach() (e.g. in the order of

(keep in mind that an O(n) find/foreach operation issued for all n

associated value and returning %TRUE if the key was found. If the key was
not found, %FALSE is returned.

If found, the stolen key and value are removed from the hash table without
calling the key and value destroy functions, and ownership is transferred to
the caller of this method, as with g_hash_table_steal(). That is the case
regardless whether @stolen_key or @stolen_value output parameters are
requested.

You can pass %NULL for @lookup_key, provided the hash and equal functions
of @hash_table are %NULL-safe.

The dictionary implementation optimizes for having all values identical to
their keys, for example by using g_hash_table_add(). When stealing both the
key and the value from such a dictionary, the value will be %NULL.&lt;/doc&gt;

GLib provides g_convert() and g_locale_to_utf8() which are likely
more convenient than the raw iconv wrappers.

Note that the behaviour of iconv() for characters which are valid in the
input character set, but which have no representation in the output character
set, is implementation defined. This function may return success (with a
positive number of non-reversible conversions as replacement characters were
used), or it may return -1 and set an error such as %EILSEQ, in such a
situation.&lt;/doc&gt;

Seldom used.

If [func@GLib.log_default_handler] is used as the log handler function, a new-line
character will automatically be appended to @..., and need not be entered
manually.

Such messages are suppressed by the [func@GLib.log_default_handler] and
[func@GLib.log_writer_default] unless the `G_MESSAGES_DEBUG` environment variable is
set appropriately. If you need to set the allowed domains at runtime, use
[func@GLib.log_writer_default_set_debug_domains].

If structured logging is enabled, this will use [func@GLib.log_structured];
otherwise it will use [func@GLib.log]. See

The callback function invoked by the #GSource should be added with
g_source_set_callback(), but it has type #GIOFunc (not #GSourceFunc).

g_io_add_watch() is a simpler interface to this same functionality, for
the case where you want to add the source to the default main loop context
at the default priority.

On Windows, polling a #GSource created to watch a channel for a socket
puts the socket in non-blocking mode. This is a side-effect of the
implementation and unavoidable.&lt;/doc&gt;

           line=&quot;3276&quot;&gt;The default log handler set up by GLib; [func@GLib.log_set_default_handler]
allows to install an alternate default log handler.

This is used if no log handler has been set for the particular log
domain and log level combination. It outputs the message to `stderr`
or `stdout` and if the log level is fatal it calls [func@GLib.BREAKPOINT]. It automatically
prints a new-line character after the message, so one does not need to be
manually included in @message.

The behavior of this log handler can be influenced by a number of
environment variables:

  - `G_MESSAGES_PREFIXED`: A `:`-separated list of log levels for which
    messages should be prefixed by the program name and PID of the
    application.
  - `G_MESSAGES_DEBUG`: A space-separated list of log domains for
    which debug and informational messages are printed. By default
    these messages are not printed. If you need to set the allowed
    domains at runtime, use [func@GLib.log_writer_default_set_debug_domains].

`stderr` is used for levels [flags@GLib.LogLevelFlags.LEVEL_ERROR],
[flags@GLib.LogLevelFlags.LEVEL_CRITICAL], [flags@GLib.LogLevelFlags.LEVEL_WARNING] and
[flags@GLib.LogLevelFlags.LEVEL_MESSAGE]. `stdout` is used for
the rest, unless `stderr` was requested by
[func@GLib.log_writer_default_set_use_stderr].

This has no effect if structured logging is enabled; see
[Using Structured Logging](logging.html#using-structured-logging).&lt;/doc&gt;

When a message with any of these levels is logged the program terminates.
You can only set the levels defined by GLib to be fatal.
[flags@GLib.LogLevelFlags.LEVEL_ERROR] is always fatal.

You can also make some message levels fatal at runtime by setting
the `G_DEBUG` environment variable (see
[Running GLib Applications](glib-running.html)).

Libraries should not call this function, as it affects all messages logged
by a process, including those from other libraries.

Structured log messages (using [func@GLib.log_structured] and
[func@GLib.log_structured_array]) are fatal only if the default log writer is used;
otherwise it is up to the writer function to determine which log messages
are fatal. See [Using Structured Logging](logging.html#using-structured-logging).&lt;/doc&gt;

[flags@GLib.LogLevelFlags.LEVEL_ERROR] is always fatal.

This has no effect on structured log messages (using [func@GLib.log_structured] or
[func@GLib.log_structured_array]). To change the fatal behaviour for specific log
messages, programs must install a custom log writer function using
[func@GLib.log_set_writer_func]. See
[Using Structured Logging](logging.html#using-structured-logging).

This function is mostly intended to be used with
[flags@GLib.LogLevelFlags.LEVEL_CRITICAL].  You should typically not set
[flags@GLib.LogLevelFlags.LEVEL_WARNING], [flags@GLib.LogLevelFlags.LEVEL_MESSAGE], [flags@GLib.LogLevelFlags.LEVEL_INFO] or
[flags@GLib.LogLevelFlags.LEVEL_DEBUG] as fatal except inside of test programs.&lt;/doc&gt;

           line=&quot;654&quot;&gt;Sets the log handler for a domain and a set of log levels.

To handle fatal and recursive messages the @log_levels parameter
must be combined with the [flags@GLib.LogLevelFlags.FLAG_FATAL] and [flags@GLib.LogLevelFlags.FLAG_RECURSION]
bit flags.

Note that since the [flags@GLib.LogLevelFlags.LEVEL_ERROR] log level is always fatal, if
you want to set a handler for this log level you must combine it with
[flags@GLib.LogLevelFlags.FLAG_FATAL].

This has no effect if structured logging is enabled; see
[Using Structured Logging](logging.html#using-structured-logging).

Here is an example for adding a log handler for all warning messages
in the default domain:

```c
g_log_set_handler (NULL, G_LOG_LEVEL_WARNING | G_LOG_FLAG_FATAL
                   | G_LOG_FLAG_RECURSION, my_log_handler, NULL);
```

This example adds a log handler for all critical messages from GTK:

```c
g_log_set_handler (&quot;Gtk&quot;, G_LOG_LEVEL_CRITICAL | G_LOG_FLAG_FATAL
                   | G_LOG_FLAG_RECURSION, my_log_handler, NULL);
```

This example adds a log handler for all messages from GLib:

```c
g_log_set_handler (&quot;GLib&quot;, G_LOG_LEVEL_MASK | G_LOG_FLAG_FATAL
                   | G_LOG_FLAG_RECURSION, my_log_handler, NULL);
```&lt;/doc&gt;

Each program should set a writer function, or the default writer
([func@GLib.log_writer_default]) will be used.

Libraries **must not** call this function — only programs are allowed to
install a writer function, as there must be a single, central point where
log messages are formatted and outputted.

There can only be one writer function. It is an error to set more than one.&lt;/doc&gt;

           filename=&quot;glib/gmessages.c&quot;
           line=&quot;1488&quot;&gt;Log a message with structured data.

The message will be passed through to the log writer set by the application
using [func@GLib.log_set_writer_func]. If the message is fatal (i.e. its log level
is [flags@GLib.LogLevelFlags.LEVEL_ERROR]), the program will be aborted by calling
[func@GLib.BREAKPOINT] at the end of this function. If the log writer returns
[enum@GLib.LogWriterOutput.UNHANDLED] (failure), no other fallback writers will be tried.
See the documentation for [type@GLib.LogWriterFunc] for information on chaining
writers.

The structured data is provided as key–value pairs, where keys are UTF-8
strings, and values are arbitrary pointers — typically pointing to UTF-8
strings, but that is not a requirement. To pass binary (non-nul-terminated)
structured data, use [func@GLib.log_structured_array]. The keys for structured data
should follow the [systemd journal
fields](https://www.freedesktop.org/software/systemd/man/systemd.journal-fields.html)
specification. It is suggested that custom keys are namespaced according to
the code which sets them. For example, custom keys from GLib all have a
`GLIB_` prefix.

Note that keys that expect UTF-8 strings (specifically `&quot;MESSAGE&quot;` and
`&quot;GLIB_DOMAIN&quot;`) must be passed as nul-terminated UTF-8 strings until GLib
version 2.74.1 because the default log handler did not consider the length of
the `GLogField`. Starting with GLib 2.74.1 this is fixed and
non-nul-terminated UTF-8 strings can be passed with their correct length.

The @log_domain will be converted into a `GLIB_DOMAIN` field. @log_level will
be converted into a
[`PRIORITY`](https://www.freedesktop.org/software/systemd/man/systemd.journal-fields.html#PRIORITY=)
field. The format string will have its placeholders substituted for the provided
values and be converted into a
[`MESSAGE`](https://www.freedesktop.org/software/systemd/man/systemd.journal-fields.html#MESSAGE=)
field.

Other fields you may commonly want to pass into this function:

 * [`MESSAGE_ID`](https://www.freedesktop.org/software/systemd/man/systemd.journal-fields.html#MESSAGE_ID=)
 * [`CODE_FILE`](https://www.freedesktop.org/software/systemd/man/systemd.journal-fields.html#CODE_FILE=)
 * [`CODE_LINE`](https://www.freedesktop.org/software/systemd/man/systemd.journal-fields.html#CODE_LINE=)
 * [`CODE_FUNC`](https://www.freedesktop.org/software/systemd/man/systemd.journal-fields.html#CODE_FUNC=)
 * [`ERRNO`](https://www.freedesktop.org/software/systemd/man/systemd.journal-fields.html#ERRNO=)

Note that `CODE_FILE`, `CODE_LINE` and `CODE_FUNC` are automatically set by
the logging macros, [func@GLib.DEBUG_HERE], [func@GLib.message], [func@GLib.warning], [func@GLib.critical],
[func@GLib.error], etc, if the symbol `G_LOG_USE_STRUCTURED` is defined before including
`glib.h`.

For example:

```c
g_log_structured (G_LOG_DOMAIN, G_LOG_LEVEL_DEBUG,
                  &quot;MESSAGE_ID&quot;, &quot;06d4df59e6c24647bfe69d2c27ef0b4e&quot;,
                  &quot;MY_APPLICATION_CUSTOM_FIELD&quot;, &quot;some debug string&quot;,
                  &quot;MESSAGE&quot;, &quot;This is a debug message about pointer %p and integer %u.&quot;,
                  some_pointer, some_integer);
```

Note that each `MESSAGE_ID` must be [uniquely and randomly
generated](https://www.freedesktop.org/software/systemd/man/systemd.journal-fields.html#MESSAGE_ID=).
If adding a `MESSAGE_ID`, consider shipping a [message
catalog](https://www.freedesktop.org/wiki/Software/systemd/catalog/) with
your software.

To pass a user data pointer to the log writer function which is specific to
this logging call, you must use [func@GLib.log_structured_array] and pass the pointer
as a field with `GLogField.length` set to zero, otherwise it will be
interpreted as a string.

For example:

```c
const GLogField fields[] = {
  { &quot;MESSAGE&quot;, &quot;This is a debug message.&quot;, -1 },
  { &quot;MESSAGE_ID&quot;, &quot;fcfb2e1e65c3494386b74878f1abf893&quot;, -1 },
  { &quot;MY_APPLICATION_CUSTOM_FIELD&quot;, &quot;some debug string&quot;, -1 },
  { &quot;MY_APPLICATION_STATE&quot;, state_object, 0 },
};
g_log_structured_array (G_LOG_LEVEL_DEBUG, fields, G_N_ELEMENTS (fields));
```

Note also that, even if no other structured fields are specified, there
must always be a `MESSAGE` key before the format string. The `MESSAGE`-format
pair has to be the last of the key-value pairs, and `MESSAGE` is the only
field for which `printf()`-style formatting is supported.

The default writer function for `stdout` and `stderr` will automatically
append a new-line character after the message, so you should not add one
manually to the format string.&lt;/doc&gt;

This version is especially useful for use in other languages, via introspection.

The only mandatory item in the @fields dictionary is the `&quot;MESSAGE&quot;` which must
contain the text shown to the user.

The values in the @fields dictionary are likely to be of type `G_VARIANT_TYPE_STRING`.
Array of bytes (`G_VARIANT_TYPE_BYTESTRING`) is also
supported. In this case the message is handled as binary and will be forwarded
to the log writer as such. The size of the array should not be higher than
`G_MAXSSIZE`. Otherwise it will be truncated to this size. For other types
[method@GLib.Variant.print] will be used to convert the value into a string.

For more details on its usage and about the parameters, see [func@GLib.log_structured].&lt;/doc&gt;

On Linux, this is typically the systemd journal, falling
back to `stdout` or `stderr` if running from the terminal or if output is
being redirected to a file.

Support for other platform-specific logging mechanisms may be added in
future. Distributors of GLib may modify this function to impose their own
(documented) platform-specific log writing policies.

This is suitable for use as a [type@GLib.LogWriterFunc], and is the default writer used
if no other is set using [func@GLib.log_set_writer_func].

As with [func@GLib.log_default_handler], this function drops debug and informational
messages unless their log domain (or `all`) is listed in the space-separated
`G_MESSAGES_DEBUG` environment variable, or set at runtime by [func@GLib.log_writer_default_set_debug_domains].

[func@GLib.log_writer_default] uses the mask set by [func@GLib.log_set_always_fatal] to
determine which messages are fatal. When using a custom writer function instead it is
up to the writer function to determine which log messages are fatal.&lt;/doc&gt;

The built-in log functions are [func@GLib.log_default_handler] for the
old-style API, and both [func@GLib.log_writer_default] and
[func@GLib.log_writer_standard_streams] for the structured API.

By default, log messages of levels [flags@GLib.LogLevelFlags.LEVEL_INFO] and
[flags@GLib.LogLevelFlags.LEVEL_DEBUG] are sent to `stdout`, and other log messages are
sent to `stderr`. This is problematic for applications that intend
to reserve `stdout` for structured output such as JSON or XML.

This function sets global state. It is not thread-aware, and should be
called at the very start of a program, before creating any other threads
or creating objects that could create worker threads of their own.&lt;/doc&gt;

ignore a message with the given domain and level.

As with [func@GLib.log_default_handler], this function drops debug and informational
messages unless their log domain (or `all`) is listed in the space-separated
`G_MESSAGES_DEBUG` environment variable, or by [func@GLib.log_writer_default_set_debug_domains].

This can be used when implementing log writers with the same filtering
behaviour as the default, but a different destination or output format:

```c
if (g_log_writer_default_would_drop (log_level, log_domain))
  return G_LOG_WRITER_HANDLED;
]|

or to skip an expensive computation if it is only needed for a debugging
message, and `G_MESSAGES_DEBUG` is not set:

```c
if (!g_log_writer_default_would_drop (G_LOG_LEVEL_DEBUG, G_LOG_DOMAIN))
  {
    g_autofree gchar *result = expensive_computation (my_object);

    g_debug (&quot;my_object result: %s&quot;, result);

g_main_context_dispatch() on any #GMainContext in the current thread.
That is, when called from the toplevel, it gives 0. When
called from within a callback from g_main_context_iteration()
(or g_main_loop_run(), etc.) it returns 1. When called from within
a callback to a recursive call to g_main_context_iteration(),
it returns 2. And so forth.

This function is useful in a situation like the following:
Imagine an extremely simple &quot;garbage collected&quot; system.

|[&amp;lt;!-- language=&quot;C&quot; --&amp;gt;
static GList *free_list;

gpointer
allocate_memory (gsize size)
{
  gpointer result = g_malloc (size);
  free_list = g_list_prepend (free_list, result);
  return result;
}

void
free_allocated_memory (void)
{
  GList *l;
  for (l = free_list; l; l = l-&amp;gt;next);
    g_free (l-&amp;gt;data);
  g_list_free (free_list);
  free_list = NULL;
 }

[...]

while (TRUE);
 {
   g_main_context_iteration (NULL, TRUE);
   free_allocated_memory();
  }
]|

This works from an application, however, if you want to do the same
thing from a library, it gets more difficult, since you no longer
control the main loop. You might think you can simply use an idle
function to make the call to free_allocated_memory(), but that
doesn&#039;t work, since the idle function could be called from a
recursive callback. This can be fixed by using g_main_depth()

|[&amp;lt;!-- language=&quot;C&quot; --&amp;gt;
gpointer
allocate_memory (gsize size)
{
  FreeListBlock *block = g_new (FreeListBlock, 1);

There is a temptation to use g_main_depth() to solve
problems with reentrancy. For instance, while waiting for data
to be received from the network in response to a menu item,
the menu item might be selected again. It might seem that
one could make the menu item&#039;s callback return immediately
and do nothing if g_main_depth() returns a value greater than 1.
However, this should be avoided since the user then sees selecting
the menu item do nothing. Furthermore, you&#039;ll find yourself adding
these checks all over your code, since there are doubtless many,
many things that the user could do. Instead, you can use the
following techniques:

1. Use gtk_widget_set_sensitive() or modal dialogs to prevent
   the user from interacting with elements while the main
   loop is recursing.

2. Avoid main loop recursion in situations where you can&#039;t handle
   arbitrary  callbacks. Instead, structure your code so that you
   simply return to the main loop and then get called again when
   there is more work to do.&lt;/doc&gt;

#GMarkupParser start_element function, dealing with common error
conditions and supporting boolean values.

This utility function is not required to write a parser but can save
a lot of typing.

The @element_name, @attribute_names, @attribute_values and @error
parameters passed to the start_element callback should be passed
unmodified to this function.

Following these arguments is a list of &quot;supported&quot; attributes to collect.
It is an error to specify multiple attributes with the same name. If any
attribute not in the list appears in the @attribute_names array then an
unknown attribute error will result.

The #GMarkupCollectType field allows specifying the type of collection
to perform and if a given attribute must appear or is optional.

The attribute name is simply the name of the attribute to collect.

The pointer should be of the appropriate type (see the descriptions
under #GMarkupCollectType) and may be %NULL in case a particular
attribute is to be allowed but ignored.

This function deals with issuing errors for missing attributes
(of type %G_MARKUP_ERROR_MISSING_ATTRIBUTE), unknown attributes
(of type %G_MARKUP_ERROR_UNKNOWN_ATTRIBUTE) and duplicate

when writing out a file to be parsed with the markup parser.

Note that this function doesn&#039;t protect whitespace and line endings
from being processed according to the XML rules for normalization
of line endings and attribute values.

Note also that this function will produce character references in
the range of &amp;amp;#x1; ... &amp;amp;#x1f; for all control sequences
except for tabstop, newline and carriage return.  The character
references in this range are not valid XML 1.0, but they are
valid XML 1.1 and will be accepted by the GMarkup parser.&lt;/doc&gt;

The returned pointer is cast to a pointer to the given type.
If @n_structs is 0 it returns %NULL.
Care is taken to avoid overflow when calculating the size of the allocated block.

Since the returned pointer is already casted to the right type,
it is normally unnecessary to cast it explicitly, and doing
so might hide memory allocation errors.&lt;/doc&gt;

@n_structs is not checked, so an overflow may lead to a remote code execution
vulnerability.&lt;/doc&gt;

`[E]xit, [H]alt, show [S]tack trace or [P]roceed`.
This function is intended to be used for debugging use only.
The following example shows how it can be used together with
the g_log() functions.

|[&amp;lt;!-- language=&quot;C&quot; --&amp;gt;
#include &amp;lt;glib.h&amp;gt;

static void
log_handler (const gchar   *log_domain,
             GLogLevelFlags log_level,
             const gchar   *message,
             gpointer       user_data)
{
  g_log_default_handler (log_domain, log_level, message, user_data);

  g_on_error_query (MY_PROGRAM_NAME);
}

int
main (int argc, char *argv[])
{
  g_log_set_handler (MY_LOG_DOMAIN,
                     G_LOG_LEVEL_WARNING |
                     G_LOG_LEVEL_ERROR |
                     G_LOG_LEVEL_CRITICAL,
                     log_handler,
                     NULL);
  ...
]|

If &quot;[E]xit&quot; is selected, the application terminates with a call
to _exit(0).

If &quot;[S]tack&quot; trace is selected, g_on_error_stack_trace() is called.
This invokes gdb, which attaches to the current process and shows
a stack trace. The prompt is then shown again.

If &quot;[P]roceed&quot; is selected, the function returns.

This function may cause different actions on non-UNIX platforms.

On Windows consider using the `G_DEBUGGER` environment
variable (see [Running GLib Applications](glib-running.html)) and
calling g_on_error_stack_trace() instead.&lt;/doc&gt;

with g_get_prgname(), assuming that you have called gtk_init() or
gdk_init().

When running on Windows, this function is *not* called by
g_on_error_query(). If called directly, it will raise an
exception, which will crash the program. If the `G_DEBUGGER` environment

handle that exception (see [Running GLib Applications](glib-running.html)).&lt;/doc&gt;

calls to g_once()  with the same #GOnce struct do not call @func
again, but return the stored result of the first call. On return
from g_once(), the status of @once will be %G_ONCE_STATUS_READY.

For example, a mutex or a thread-specific data key must be created
exactly once. In a threaded environment, calling g_once() ensures
that the initialization is serialized across multiple threads.

Calling g_once() recursively on the same #GOnce struct in
@func will lead to a deadlock.

blocked until initialization completed. To be used in constructs

           line=&quot;1017&quot;&gt;A wrapper for the POSIX open() function. The open() function is
used to convert a pathname into a file descriptor.

On POSIX systems file descriptors are implemented by the operating
system. On Windows, it&#039;s the C library that implements open() and
file descriptors. The actual Win32 API for opening files is quite
different, see MSDN documentation for CreateFile(). The Win32 API
uses file handles, which are more randomish integers, not small
integers like file descriptors.

Because file descriptors are specific to the C library on Windows,
the file descriptor returned by this function makes sense only to
functions in the same C library. Thus if the GLib-using code uses a
different C library than GLib does, the file descriptor returned by
this function cannot be passed to C library functions like write()
or read().

See your C library manual for more details about open().&lt;/doc&gt;

           line=&quot;2415&quot;&gt;Returns %TRUE if the given @file_name is an absolute file name.
Note that this is a somewhat vague concept on Windows.

On POSIX systems, an absolute file name is well-defined. It always
starts from the single root directory. For example &quot;/usr/local&quot;.

On Windows, the concepts of current drive and drive-specific
current directory introduce vagueness. This function interprets as
an absolute file name one that either begins with a directory
separator such as &quot;\Users\tml&quot; or begins with the root on a drive,
for example &quot;C:\Windows&quot;. The first case also includes UNC paths
such as &quot;\\\\myserver\docs\foo&quot;. In all cases, either slashes or
backslashes are accepted.

Note that a file name relative to the current drive root does not
truly specify a file uniquely over time and across processes, as
the current drive is a per-process value and can be changed.

File names relative the current directory on some specific drive,
such as &quot;D:foo/bar&quot;, are not interpreted as absolute by this
function, but they obviously are not relative to the normal current
directory as returned by getcwd() or g_get_current_dir()
either. Such paths should be avoided, or need to be handled using
Windows-specific code.&lt;/doc&gt;

omitted by passing %NULL, this is more efficient if the reversed
version of the string to be matched is not at hand, as
g_pattern_match() will only construct it if the compiled pattern
requires reverse matches.

Note that, if the user code will (possibly) match a string against a
multitude of patterns containing wildcards, chances are high that
some patterns will require a reversed string. In this case, it&#039;s
more efficient to provide the reversed string to avoid multiple
constructions thereof in the various calls to g_pattern_match().

Note also that the reverse of a UTF-8 encoded string can in general
not be obtained by g_strreverse(). This works only if the string
does not contain any multibyte characters. GLib offers the
g_utf8_strreverse() function to reverse UTF-8 encoded strings.&lt;/doc&gt;

This is used internally by #GMainContext, but it can be called
directly if you need to block until a file descriptor is ready, but
don&#039;t want to run the full main loop.

Each element of @fds is a #GPollFD describing a single file
descriptor to poll. The @fd field indicates the file descriptor,
and the @events field indicates the events to poll for. On return,
the @revents fields will be filled with the events that actually
occurred.

On POSIX systems, the file descriptors in @fds can be any sort of
file descriptor, but the situation is much more complicated on
Windows. If you need to use g_poll() in code that has to run on
Windows, the easiest solution is to construct all of your
#GPollFDs with g_io_channel_win32_make_pollfd().&lt;/doc&gt;

If @format or @args are invalid, `0` is returned. This could happen if, for
example, @format contains an `%lc` or `%ls` placeholder and @args contains a
wide character which cannot be represented in multibyte encoding. `0`
can also be returned legitimately if, for example, @format is `%s` and @args
is an empty string. The caller is responsible for differentiating these two
return cases if necessary. It is recommended to not use `%lc` or `%ls`
placeholders in any case, as their behaviour is locale-dependent.&lt;/doc&gt;

and setting the reference count to 1.

This avoids having to copy such data manually.
After this call, @data belongs to the #GPtrArray and may no longer be
modified by the caller. The memory of @data has to be dynamically
allocated and will eventually be freed with g_free().

The length is calculated by iterating through @data until the first %NULL
element is found.

It also sets @element_free_func for freeing each element when the array is
destroyed either via g_ptr_array_unref(), when g_ptr_array_free() is called
with @free_segment set to %TRUE or when removing elements.

Do not use it if the @data length is greater than %G_MAXUINT. #GPtrArray
stores the length of its data in #guint, which may be shorter than
#gsize.&lt;/doc&gt;

that if a new #GQuark is created the string itself is used rather
than a copy. This saves memory, but can only be used if the string
will continue to exist until the program terminates. It can be used
with statically allocated strings in the main program, but not with
statically allocated memory in dynamically loaded modules, if you
expect to ever unload the module again (e.g. do not use this
function in GTK theme engines).

running. In particular, this means it cannot be used to initialize global

If the pattern does not match anywhere in the string, then the
whole string is returned as the first token.

This function is equivalent to g_regex_split() but it does
not require to compile the pattern with g_regex_new(), avoiding
some lines of code when you need just to do a split without
extracting substrings, capture counts, and so on.

If this function is to be called on the same @pattern more than
once, it&#039;s more efficient to compile the pattern once with
g_regex_new() and then use g_regex_split().

As a special case, the result of splitting the empty string &quot;&quot;
is an empty vector, not a vector containing a single string.
The reason for this special case is that being able to represent
an empty vector is typically more useful than consistent handling
of empty elements. If you do need to represent empty elements,
you&#039;ll need to check for the empty string before calling this
function.

A pattern that can match empty strings splits @string into
separate characters wherever it matches the empty string between
characters. For example splitting &quot;ab c&quot; using as a separator
&quot;\s*&quot;, you will get &quot;a&quot;, &quot;b&quot; and &quot;c&quot;.&lt;/doc&gt;

deletes a name from the filesystem.

See your C library manual for more details about how remove() works
on your system. On Unix, remove() removes also directories, as it
calls unlink() for files and rmdir() for directories. On Windows,
although remove() in the C library only works for files, this
function tries first remove() and then if that fails rmdir(), and
thus works for both files and directories. Note however, that on
Windows, it is in general not possible to remove a file that is
open to some process, or mapped into memory.

If this function fails on Windows you can&#039;t infer too much from the
errno value. rmdir() is tried regardless of what caused remove() to
fail. Any errno value set by remove() will be overwritten by that
set by rmdir().&lt;/doc&gt;

Contrast with g_set_prgname(), which sets a non-localized name.
g_set_prgname() will be called automatically by gtk_init(),

Note that for thread safety reasons, this function can only
be called once.

The application name will be used in contexts such as error messages,

gdk_init(), which is called by gtk_init() and the
#GtkApplication::startup handler. The program name is found by

Note that on some systems, when variables are overwritten, the memory
used for the previous variables and its value isn&#039;t reclaimed.

You should be mindful of the fact that environment variable handling
in UNIX is not thread-safe, and your program may crash if one thread
calls g_setenv() while another thread is calling getenv(). (And note
that many functions, such as gettext(), call getenv() internally.)
This function is only safe to use at the very start of your program,
before creating any other threads (or creating objects that create
worker threads of their own).

If you need to set up the environment for a child process, you can
use g_get_environ() to get an environment array, modify that with
g_environ_setenv() and g_environ_unsetenv(), and then pass that
array directly to execvpe(), g_spawn_async(), or the like.&lt;/doc&gt;

the shell would, but without many of the expansions the shell would

The results are defined to be the same as those you would get from
a UNIX98 `/bin/sh`, as long as the input contains none of the
unsupported shell expansions. If the input does contain such expansions,
they are passed through literally.

Possible errors are those from the %G_SHELL_ERROR domain.

In particular, if @command_line is an empty string (or a string containing
only whitespace), %G_SHELL_ERROR_EMPTY_STRING will be returned. It’s
guaranteed that @argvp will be a non-empty array if this function returns
successfully.

           line=&quot;233&quot;&gt;Unquotes a string as the shell (/bin/sh) would.

This function only handles quotes; if a string contains file globs,
arithmetic operators, variables, backticks, redirections, or other
special-to-the-shell features, the result will be different from the
result a real shell would produce (the variables, backticks, etc.
will be passed through literally instead of being expanded).

This function is guaranteed to succeed if applied to the result of
g_shell_quote(). If it fails, it returns %NULL and sets the
error.

The @quoted_string need not actually contain quoted or escaped text;
g_shell_unquote() simply goes through the string and unquotes/unescapes
anything that the shell would. Both single and double quotes are
handled, as are escapes including escaped newlines.

The return value must be freed with g_free().

Possible errors are in the %G_SHELL_ERROR domain.

Shell quoting rules are a bit strange. Single quotes preserve the
literal string exactly. escape sequences are not allowed; not even
`\&#039;` - if you want a `&#039;` in the quoted text, you have to do something
like `&#039;foo&#039;\&#039;&#039;bar&#039;`. Double quotes allow `$`, ```, `&quot;`, `\`, and
newline to be escaped with backslash. Otherwise double quotes
preserve things literally.&lt;/doc&gt;

           line=&quot;133&quot;&gt;A safer form of the standard sprintf() function. The output is guaranteed
to not exceed @n characters (including the terminating nul character), so
it is easy to ensure that a buffer overflow cannot occur.

See also [func@GLib.strdup_printf].

In versions of GLib prior to 1.2.3, this function may return -1 if the
output was truncated, and the truncated string may not be nul-terminated.
In versions prior to 1.3.12, this function returns the length of the output
string.

The return value of g_snprintf() conforms to the snprintf()
function as standardized in ISO C99. Note that this is different from
traditional `snprintf()`, which returns the length of the output string.

The format string may contain positional parameters, as specified in
the Single Unix Specification.&lt;/doc&gt;

The ID of a #GSource is given by g_source_get_id(), or will be
returned by the functions g_source_attach(), g_idle_add(),
g_idle_add_full(), g_timeout_add(), g_timeout_add_full(),
g_child_watch_add(), g_child_watch_add_full(), g_io_add_watch(), and
g_io_add_watch_full().

It is a programmer error to attempt to remove a non-existent source.

More specifically: source IDs can be reissued after a source has been
destroyed and therefore it is never valid to use this function with a
source ID which may have already been removed.  An example is when
scheduling an idle to run in another thread with g_idle_add(): the
idle may already have run and been removed by the time this function
is called on its (now invalid) source ID.  This source ID may have
been reissued, leading to the operation being performed against the

           line=&quot;151&quot;&gt;Executes a child program asynchronously.

See g_spawn_async_with_pipes() for a full description; this function
simply calls the g_spawn_async_with_pipes() without any pipes.

You should call g_spawn_close_pid() on the returned child process
reference when you don&#039;t need it any more.

If you are writing a GTK application, and the program you are spawning is a
graphical application too, then to ensure that the spawned program opens its
windows on the right screen, you may want to use #GdkAppLaunchContext,
#GAppLaunchContext, or set the %DISPLAY environment variable.

Note that the returned @child_pid on Windows is a handle to the child
process and not its identifier. Process handles and process identifiers
are different concepts on Windows.&lt;/doc&gt;

           line=&quot;556&quot;&gt;Executes a child program asynchronously (your program will not
block waiting for the child to exit).

The child program is specified by the only argument that must be
provided, @argv. @argv should be a %NULL-terminated array of strings,
to be passed as the argument vector for the child. The first string
in @argv is of course the name of the program to execute. By default,
the name of the program must be a full path. If @flags contains the
%G_SPAWN_SEARCH_PATH flag, the `PATH` environment variable is used to
search for the executable. If @flags contains the
%G_SPAWN_SEARCH_PATH_FROM_ENVP flag, the `PATH` variable from @envp
is used to search for the executable. If both the
%G_SPAWN_SEARCH_PATH and %G_SPAWN_SEARCH_PATH_FROM_ENVP flags are
set, the `PATH` variable from @envp takes precedence over the
environment variable.

If the program name is not a full path and %G_SPAWN_SEARCH_PATH flag
is not used, then the program will be run from the current directory
(or @working_directory, if specified); this might be unexpected or even
dangerous in some cases when the current directory is world-writable.

On Windows, note that all the string or string vector arguments to
this function and the other `g_spawn*()` functions are in UTF-8, the
GLib file name encoding. Unicode characters that are not part of
the system codepage passed in these arguments will be correctly
available in the spawned program only if it uses wide character API
to retrieve its command line. For C programs built with Microsoft&#039;s
tools it is enough to make the program have a `wmain()` instead of
`main()`. `wmain()` has a wide character argument vector as parameter.

At least currently, mingw doesn&#039;t support `wmain()`, so if you use
mingw to develop the spawned program, it should call
g_win32_get_command_line() to get arguments in UTF-8.

On Windows the low-level child process creation API `CreateProcess()`
doesn&#039;t use argument vectors, but a command line. The C runtime
library&#039;s `spawn*()` family of functions (which g_spawn_async_with_pipes()
eventually calls) paste the argument vector elements together into
a command line, and the C runtime startup code does a corresponding
reconstruction of an argument vector from the command line, to be
passed to `main()`. Complications arise when you have argument vector
elements that contain spaces or double quotes. The `spawn*()` functions
don&#039;t do any quoting or escaping, but on the other hand the startup
code does do unquoting and unescaping in order to enable receiving
arguments with embedded spaces or double quotes. To work around this
asymmetry, g_spawn_async_with_pipes() will do quoting and escaping on
argument vector elements that need it before calling the C runtime
`spawn()` function.

The returned @child_pid on Windows is a handle to the child
process, not its identifier. Process handles and process
identifiers are different concepts on Windows.

@envp is a %NULL-terminated array of strings, where each string
has the form `KEY=VALUE`. This will become the child&#039;s environment.
If @envp is %NULL, the child inherits its parent&#039;s environment.

@flags should be the bitwise OR of any flags you want to affect the
function&#039;s behaviour. The %G_SPAWN_DO_NOT_REAP_CHILD means that the
child will not automatically be reaped; you must use a child watch
(g_child_watch_add()) to be notified about the death of the child process,
otherwise it will stay around as a zombie process until this process exits.
Eventually you must call g_spawn_close_pid() on the @child_pid, in order to
free resources which may be associated with the child process. (On Unix,
using a child watch is equivalent to calling waitpid() or handling
the `SIGCHLD` signal manually. On Windows, calling g_spawn_close_pid()
is equivalent to calling `CloseHandle()` on the process handle returned
in @child_pid). See g_child_watch_add().

Open UNIX file descriptors marked as `FD_CLOEXEC` will be automatically
closed in the child process. %G_SPAWN_LEAVE_DESCRIPTORS_OPEN means that
other open file descriptors will be inherited by the child; otherwise all
descriptors except stdin/stdout/stderr will be closed before calling `exec()`
in the child. %G_SPAWN_SEARCH_PATH means that @argv[0] need not be an
absolute path, it will be looked for in the `PATH` environment
variable. %G_SPAWN_SEARCH_PATH_FROM_ENVP means need not be an
absolute path, it will be looked for in the `PATH` variable from
@envp. If both %G_SPAWN_SEARCH_PATH and %G_SPAWN_SEARCH_PATH_FROM_ENVP
are used, the value from @envp takes precedence over the environment.

%G_SPAWN_CHILD_INHERITS_STDIN means that the child will inherit the parent&#039;s
standard input (by default, the child&#039;s standard input is attached to
`/dev/null`). %G_SPAWN_STDIN_FROM_DEV_NULL explicitly imposes the default
behavior. Both flags cannot be enabled at the same time and, in both cases,
the @stdin_pipe_out argument is ignored.

%G_SPAWN_STDOUT_TO_DEV_NULL means that the child&#039;s standard output
will be discarded (by default, it goes to the same location as the parent&#039;s
standard output). %G_SPAWN_CHILD_INHERITS_STDOUT explicitly imposes the
default behavior. Both flags cannot be enabled at the same time and, in
both cases, the @stdout_pipe_out argument is ignored.

%G_SPAWN_STDERR_TO_DEV_NULL means that the child&#039;s standard error
will be discarded (by default, it goes to the same location as the parent&#039;s
standard error). %G_SPAWN_CHILD_INHERITS_STDERR explicitly imposes the
default behavior. Both flags cannot be enabled at the same time and, in
both cases, the @stderr_pipe_out argument is ignored.

It is valid to pass the same FD in multiple parameters (e.g. you can pass
a single FD for both @stdout_fd and @stderr_fd, and include it in
@source_fds too).

@source_fds and @target_fds allow zero or more FDs from this process to be
remapped to different FDs in the spawned process. If @n_fds is greater than
zero, @source_fds and @target_fds must both be non-%NULL and the same length.
Each FD in @source_fds is remapped to the FD number at the same index in
@target_fds. The source and target FD may be equal to simply propagate an FD
to the spawned process. FD remappings are processed after standard FDs, so
any target FDs which equal @stdin_fd, @stdout_fd or @stderr_fd will overwrite
them in the spawned process.

@source_fds is supported on Windows since 2.72.

%G_SPAWN_FILE_AND_ARGV_ZERO means that the first element of @argv is
the file to execute, while the remaining elements are the actual
argument vector to pass to the file. Normally g_spawn_async_with_pipes()
uses @argv[0] as the file to execute, and passes all of @argv to the child.

@child_setup and @user_data are a function and user data. On POSIX
platforms, the function is called in the child after GLib has
performed all the setup it plans to perform (including creating
pipes, closing file descriptors, etc.) but before calling `exec()`.
That is, @child_setup is called just before calling `exec()` in the
child. Obviously actions taken in this function will only affect
the child, not the parent.

On Windows, there is no separate `fork()` and `exec()` functionality.
Child processes are created and run with a single API call,
`CreateProcess()`. There is no sensible thing @child_setup
could be used for on Windows so it is ignored and not called.

If non-%NULL, @child_pid will on Unix be filled with the child&#039;s
process ID. You can use the process ID to send signals to the child,
or to use g_child_watch_add() (or `waitpid()`) if you specified the
%G_SPAWN_DO_NOT_REAP_CHILD flag. On Windows, @child_pid will be
filled with a handle to the child process only if you specified the
%G_SPAWN_DO_NOT_REAP_CHILD flag. You can then access the child
process using the Win32 API, for example wait for its termination
with the `WaitFor*()` functions, or examine its exit code with
`GetExitCodeProcess()`. You should close the handle with `CloseHandle()`
or g_spawn_close_pid() when you no longer need it.

If non-%NULL, the @stdin_pipe_out, @stdout_pipe_out, @stderr_pipe_out
locations will be filled with file descriptors for writing to the child&#039;s
standard input or reading from its standard output or standard error.
The caller of g_spawn_async_with_pipes() must close these file descriptors
when they are no longer in use. If these parameters are %NULL, the
corresponding pipe won&#039;t be created.

If @stdin_pipe_out is %NULL, the child&#039;s standard input is attached to
`/dev/null` unless %G_SPAWN_CHILD_INHERITS_STDIN is set.

If @stderr_pipe_out is NULL, the child&#039;s standard error goes to the same
location as the parent&#039;s standard error unless %G_SPAWN_STDERR_TO_DEV_NULL
is set.

If @stdout_pipe_out is NULL, the child&#039;s standard output goes to the same
location as the parent&#039;s standard output unless %G_SPAWN_STDOUT_TO_DEV_NULL
is set.

@error can be %NULL to ignore errors, or non-%NULL to report errors.
If an error is set, the function returns %FALSE. Errors are reported
even if they occur in the child (for example if the executable in
`@argv[0]` is not found). Typically the `message` field of returned
errors should be displayed to users. Possible errors are those from
the %G_SPAWN_ERROR domain.

If an error occurs, @child_pid, @stdin_pipe_out, @stdout_pipe_out,
and @stderr_pipe_out will not be filled with valid values.

If @child_pid is not %NULL and an error does not occur then the returned
process reference must be closed using g_spawn_close_pid().

On modern UNIX platforms, GLib can use an efficient process launching
codepath driven internally by `posix_spawn()`. This has the advantage of
avoiding the fork-time performance costs of cloning the parent process
address space, and avoiding associated memory overcommit checks that are
not relevant in the context of immediately executing a distinct process.
This optimized codepath will be used provided that the following conditions
are met:

1. %G_SPAWN_DO_NOT_REAP_CHILD is set
2. %G_SPAWN_LEAVE_DESCRIPTORS_OPEN is set
3. %G_SPAWN_SEARCH_PATH_FROM_ENVP is not set
4. @working_directory is %NULL
5. @child_setup is %NULL
6. The program is of a recognised binary format, or has a shebang.
   Otherwise, GLib will have to execute the program through the
   shell, which is not done using the optimized codepath.

If you are writing a GTK application, and the program you are spawning is a
graphical application too, then to ensure that the spawned program opens its
windows on the right screen, you may want to use #GdkAppLaunchContext,
#GAppLaunchContext, or set the `DISPLAY` environment variable.&lt;/doc&gt;

Despite the name of the function, @wait_status must be the wait status

etc. On Unix platforms, it is incorrect for it to be the exit status
as passed to `exit()` or returned by g_subprocess_get_exit_status() or
`WEXITSTATUS()`.&lt;/doc&gt;

           line=&quot;1036&quot;&gt;Set @error if @wait_status indicates the child exited abnormally
(e.g. with a nonzero exit code, or via a fatal signal).

The g_spawn_sync() and g_child_watch_add() family of APIs return the
status of subprocesses encoded in a platform-specific way.
On Unix, this is guaranteed to be in the same format waitpid() returns,
and on Windows it is guaranteed to be the result of GetExitCodeProcess().

Prior to the introduction of this function in GLib 2.34, interpreting
@wait_status required use of platform-specific APIs, which is problematic
for software using GLib as a cross-platform layer.

Additionally, many programs simply want to determine whether or not
the child exited successfully, and either propagate a #GError or
print a message to standard error. In that common case, this function
can be used. Note that the error message in @error will contain
human-readable information about the wait status.

The @domain and @code of @error have special semantics in the case
where the process has an &quot;exit code&quot;, as opposed to being killed by
a signal. On Unix, this happens if WIFEXITED() would be true of
@wait_status. On Windows, it is always the case.

The special semantics are that the actual exit code will be the
code set in @error, and the domain will be %G_SPAWN_EXIT_ERROR.
This allows you to differentiate between different exit codes.

If the process was terminated by some means other than an exit
status (for example if it was killed by a signal), the domain will be
%G_SPAWN_ERROR and the code will be %G_SPAWN_ERROR_FAILED.

This function just offers convenience; you can of course also check
the available platform via a macro such as %G_OS_UNIX, and use
WIFEXITED() and WEXITSTATUS() on @wait_status directly. Do not attempt
to scan or parse the error message string; it may be translated and/or
change in future versions of GLib.

Prior to version 2.70, g_spawn_check_exit_status() provides the same
functionality, although under a misleading name.&lt;/doc&gt;

removed, taking a command line instead of an argument vector.

See g_spawn_sync() for full details.

The @command_line argument will be parsed by g_shell_parse_argv().

Unlike g_spawn_sync(), the %G_SPAWN_SEARCH_PATH flag is enabled.
Note that %G_SPAWN_SEARCH_PATH can have security implications, so
consider using g_spawn_sync() directly if appropriate.

Possible errors are those from g_spawn_sync() and those
from g_shell_parse_argv().

If @wait_status is non-%NULL, the platform-specific status of
the child is stored there; see the documentation of
g_spawn_check_wait_status() for how to use and interpret this.
On Unix platforms, note that it is usually not equal
to the integer passed to `exit()` or returned from `main()`.

On Windows, please note the implications of g_shell_parse_argv()
parsing @command_line. Parsing is done according to Unix shell rules, not
Windows command interpreter rules.
Space is a separator, and backslashes are
special. Thus you cannot simply pass a @command_line containing
canonical Windows paths, like &quot;c:\\program files\\app\\app.exe&quot;, as
the backslashes will be eaten, and the space will act as a
separator. You need to enclose such paths with single quotes, like
&quot;&#039;c:\\program files\\app\\app.exe&#039; &#039;e:\\folder\\argument.txt&#039;&quot;.&lt;/doc&gt;

On Unix platforms, note that it is usually not equal

Note that it is invalid to pass %G_SPAWN_DO_NOT_REAP_CHILD in

           filename=&quot;glib/gstdio.c&quot;
           line=&quot;1292&quot;&gt;A wrapper for the POSIX stat() function. The stat() function
returns information about a file. On Windows the stat() function in
the C library checks only the FAT-style READONLY attribute and does
not look at the ACL at all. Thus on Windows the protection bits in
the @st_mode field are a fabrication of little use.

On Windows the Microsoft C libraries have several variants of the
stat struct and stat() function with names like _stat(), _stat32(),
_stat32i64() and _stat64i32(). The one used here is for 32-bit code
the one with 32-bit size and time fields, specifically called _stat32().

In Microsoft&#039;s compiler, by default struct stat means one with
64-bit time fields while in MinGW struct stat is the legacy one
with 32-bit fields. To hopefully clear up this messs, the gstdio.h
header defines a type #GStatBuf which is the appropriate struct type
depending on the platform and/or compiler being used. On POSIX it
is just struct stat, but note that even on POSIX platforms, stat()
might be a macro.

See your C library manual for more details about stat().&lt;/doc&gt;

           line=&quot;177&quot;&gt;Sets @pp to %NULL, returning the value that was there before.

Conceptually, this transfers the ownership of the pointer from the
referenced variable to the &quot;caller&quot; of the macro (ie: &quot;steals&quot; the
reference).

The return value will be properly typed, according to the type of
@pp.

This can be very useful when combined with g_autoptr() to prevent the
return value of a function from being automatically freed.  Consider
the following example (which only works on GCC and clang):

|[
GObject *
create_object (void)
{
  g_autoptr(GObject) obj = g_object_new (G_TYPE_OBJECT, NULL);

  if (early_error_case)
    return NULL;

  return g_steal_pointer (&amp;amp;obj);
}
]|

It can also be used in similar ways for &#039;out&#039; parameters and is
particularly useful for dealing with optional out parameters:

|[
gboolean
get_object (GObject **obj_out)
{
  g_autoptr(GObject) obj = g_object_new (G_TYPE_OBJECT, NULL);

  if (early_error_case)
    return FALSE;

  if (obj_out)
    *obj_out = g_steal_pointer (&amp;amp;obj);

  return TRUE;
}
]|

In the above example, the object will be automatically freed in the
early error case and also in the case that %NULL was given for
@obj_out.&lt;/doc&gt;

This function is typically used for hash table comparisons, but can be used
for general purpose comparisons of non-%NULL strings. For a %NULL-safe string

This function implements the widely used &quot;djb&quot; hash apparently
posted by Daniel Bernstein to comp.lang.c some time ago.  The 32
bit unsigned hash value starts at 5381 and for each byte &#039;c&#039; in
the string, is updated: `hash = hash * 33 + c`. This function
uses the signed value of each byte.

It can be passed to g_hash_table_new() as the @hash_func parameter,
when using non-%NULL strings as keys in a #GHashTable.

Note that this function may not be a perfect fit for all use cases.
For example, it produces some hash collisions with strings as short
as 2.&lt;/doc&gt;

           line=&quot;3125&quot;&gt;Checks if a search conducted for @search_term should match
@potential_hit.

This function calls [func@GLib.str_tokenize_and_fold] on both
@search_term and @potential_hit. ASCII alternates are never taken
for @search_term but will be taken for @potential_hit according to
the value of @accept_alternates.

A hit occurs when each folded token in @search_term is a prefix of a
folded token from @potential_hit.

Depending on how you&#039;re performing the search, it will typically be
faster to call `g_str_tokenize_and_fold()` on each string in
your corpus and build an index on the returned folded tokens, then
call `g_str_tokenize_and_fold()` on the search term and
perform lookups into that index.

As some examples, searching for ‘fred’ would match the potential hit
‘Smith, Fred’ and also ‘Frédéric’.  Searching for ‘Fréd’ would match
‘Frédéric’ but not ‘Frederic’ (due to the one-directional nature of
accent matching).  Searching ‘fo’ would match ‘Foo’ and ‘Bar Foo
Baz’, but not ‘SFO’ (because no word has ‘fo’ as a prefix).&lt;/doc&gt;

For best results, @str should be in composed normalised form.

This function performs a reasonably good set of character
replacements.  The particular set of replacements that is done may
change by version or even by runtime environment.

If the source language of @str is known, it can used to improve the
accuracy of the translation by passing it as @from_locale.  It should
be a valid POSIX locale string (of the form
`language[_territory][.codeset][@modifier]`).

If @from_locale is %NULL then the current locale is used.

If you want to do translation for no specific locale, and you want it
to be done independently of the currently locale, specify `&quot;C&quot;` for
@from_locale.&lt;/doc&gt;

A token is a non-empty sequence of alphanumeric characters in the
source string, separated by non-alphanumeric characters.  An
&quot;alphanumeric&quot; character for this purpose is one that matches
[func@GLib.unichar_isalnum] or [func@GLib.unichar_ismark].

Each token is then (Unicode) normalised and case-folded.  If
@ascii_alternates is non-`NULL` and some of the returned tokens
contain non-ASCII characters, ASCII alternatives will be generated.

The number of ASCII alternatives that are generated and the method
for doing so is unspecified, but @translit_locale (if specified) may
improve the transliteration if the language of the source string is
known.&lt;/doc&gt;

The returned string is guaranteed to be non-NULL, unless @format
contains `%lc` or `%ls` conversions, which can fail if no multibyte
representation is available for the given character.

the lifetime of the process. If the error code is unknown, it returns a
string like “Unknown error &amp;lt;code\&amp;gt;”.

Note that the string may be translated according to the current locale.

The value of `errno` will not be changed by this function. However, it may
be changed by intermediate function calls, so you should save its value
as soon as the call returns:

saved_errno = errno;

g_strerror (saved_errno);

exceed @dest_size.

At most @dest_size - 1 characters will be copied. Unlike `strncat()`,
@dest_size is the full size of dest, not the space left over. This
function does not allocate memory. It always nul-terminates (unless
@dest_size == 0 or there were no nul characters in the @dest_size
characters of dest to start with).

Caveat: this is supposedly a more secure alternative to `strcat()` or
`strncat()`, but for real security [func@GLib.strconcat] is harder to mess up.&lt;/doc&gt;

           line=&quot;1416&quot;&gt;Portability wrapper that calls `strlcpy()` on systems which have it,
and emulates `strlcpy()` otherwise. Copies @src to @dest; @dest is
guaranteed to be nul-terminated; @src must be nul-terminated;
@dest_size is the buffer size, not the number of bytes to copy.

At most @dest_size - 1 characters will be copied. Always nul-terminates
(unless @dest_size is 0). This function does not allocate memory. Unlike
`strncpy()`, this function doesn&#039;t pad @dest (so it&#039;s often faster). It
returns the size of the attempted result, `strlen (src)`, so if
@retval &amp;gt;= @dest_size, truncation occurred.

Caveat: `strlcpy()` is supposedly more secure than `strcpy()` or `strncpy()`,
but if you really want to avoid screwups, [func@GLib.strdup] is an even better
idea.&lt;/doc&gt;

           line=&quot;1955&quot;&gt;A case-insensitive string comparison, corresponding to the standard
`strncasecmp()` function on platforms which support it. It is similar
to [func@GLib.strcasecmp] except it only compares the first @n characters of
the strings.&lt;/doc&gt;
      &lt;doc-deprecated xml:space=&quot;preserve&quot;&gt;The problem with `g_strncasecmp()` is that it does
  the comparison by calling `toupper()`/`tolower()`. These functions
  are locale-specific and operate on single bytes. However, it is
  impossible to handle things correctly from an internationalization
  standpoint by operating on bytes, since characters may be multibyte.
  Thus `g_strncasecmp()` is broken if your string is guaranteed to be
  ASCII, since it is locale-sensitive, and it&#039;s broken if your string
  is localized, since it doesn&#039;t work on many encodings at all,
  including UTF-8, EUC-JP, etc.

  There are therefore two replacement techniques: [func@GLib.ascii_strncasecmp],
  which only works on ASCII and is not locale-sensitive, and
  [func@GLib.utf8_casefold] followed by `strcmp()` on the resulting strings,
  which is good for case-insensitive sorting of UTF-8.&lt;/doc-deprecated&gt;

As a special case, the result of splitting the empty string &quot;&quot; is an empty
array, not an array containing a single string. The reason for this
special case is that being able to represent an empty array is typically
more useful than consistent handling of empty elements. If you do need
to represent empty elements, you&#039;ll need to check for the empty string

           line=&quot;2428&quot;&gt;Splits @string into a number of tokens not containing any of the characters
in @delimiters. A token is the (possibly empty) longest string that does not
contain any of the characters in @delimiters. If @max_tokens is reached, the
remainder is appended to the last token.

For example, the result of g_strsplit_set (&quot;abc:def/ghi&quot;, &quot;:/&quot;, -1) is an
array containing the three strings &quot;abc&quot;, &quot;def&quot;, and &quot;ghi&quot;.

The result of g_strsplit_set (&quot;:def/ghi:&quot;, &quot;:/&quot;, -1) is an array containing
the four strings &quot;&quot;, &quot;def&quot;, &quot;ghi&quot;, and &quot;&quot;.

As a special case, the result of splitting the empty string &quot;&quot; is an empty
array, not an array containing a single string. The reason for this
special case is that being able to represent an empty array is typically
more useful than consistent handling of empty elements. If you do need
to represent empty elements, you&#039;ll need to check for the empty string
before calling `g_strsplit_set()`.

Note that this function works on bytes not characters, so it can&#039;t be used
to delimit UTF-8 strings for anything but ASCII characters.&lt;/doc&gt;

It calls the standard `strtod()` function to handle the conversion, but
if the string is not completely converted it attempts the conversion
again with [func@GLib.ascii_strtod], and returns the best match.

This function should seldom be used. The normal situation when reading
numbers not for human consumption is to use [func@GLib.ascii_strtod]. Only when
you know that you must expect both locale formatted and C formatted numbers
should you use this. Make sure that you don&#039;t pass strings such as comma
separated lists of values, since the commas may be interpreted as a decimal
point in some locales, causing unexpected results.&lt;/doc&gt;

Bug URIs are constructed from a base URI set with g_test_bug_base()
and @bug_uri_snippet. If g_test_bug_base() has not been called, it is
assumed to be the empty string, so a full URI can be provided to
g_test_bug() instead.

Since GLib 2.70, the base URI is not prepended to @bug_uri_snippet if it
is already a valid URI.&lt;/doc&gt;

The base URI is used to construct bug report messages for
g_test_message() when g_test_bug() is called.
Calling this function outside of a test case sets the
default base URI for all test cases. Calling it from within
a test case changes the base URI for the scope of the test
case only.
Bug URIs are constructed by appending a bug specific URI
portion to @uri_pattern, or by replacing the special string
`%s` within @uri_pattern if that is present.

If g_test_bug_base() is not called, bug URIs are formed solely
from the value provided by g_test_bug().&lt;/doc&gt;

           line=&quot;4496&quot;&gt;Creates the pathname to a data file that is required for a test.

This function is conceptually similar to g_build_filename() except
that the first argument has been replaced with a #GTestFileType
argument.

The data file should either have been distributed with the module
containing the test (%G_TEST_DIST) or built as part of the build
system of that module (%G_TEST_BUILT).

In order for this function to work in srcdir != builddir situations,
the G_TEST_SRCDIR and G_TEST_BUILDDIR environment variables need to
have been defined.  As of 2.38, this is done by the glib.mk
included in GLib.  Please ensure that your copy is up to date before
using this function.

In case neither variable is set, this function will fall back to
using the dirname portion of argv[0], possibly removing &quot;.libs&quot;.
This allows for casual running of tests directly from the commandline
in the srcdir == builddir case and should also support running of
installed tests, assuming the data files have been installed in the
same relative path as the test binary.&lt;/doc&gt;

This API is fairly low level, and calling g_test_add() or g_test_add_func()
is preferable.

When this test is executed, a fixture structure of size @data_size
will be automatically allocated and filled with zeros. Then @data_setup is
called to initialize the fixture. After fixture setup, the actual test
function @data_test is called. Once the test run completes, the
fixture structure is torn down by calling @data_teardown and
after that the memory is automatically released by the test framework.

Splitting up a test run into fixture setup, test function and
fixture teardown is most useful if the same fixture type is used for
multiple tests. In this cases, g_test_create_case() will be
called with the same type of fixture (the @data_size argument), but varying
@test_name and @data_test arguments.&lt;/doc&gt;

with text matching @pattern, is expected to be logged.

When this message is logged, it will not be printed, and the test case will
not abort.

This API may only be used with the old logging API ([func@GLib.log] without
`G_LOG_USE_STRUCTURED` defined). It will not work with the structured logging
API. See [Testing for Messages](logging.html#testing-for-messages).

Use [func@GLib.test_assert_expected_messages] to assert that all
previously-expected messages have been seen and suppressed.

You can call this multiple times in a row, if multiple messages are
expected as a result of a single call. (The messages must appear in
the same order as the calls to [func@GLib.test_expect_message].)

For example:

```c
// g_main_context_push_thread_default() should fail if the
// context is already owned by another thread.
g_test_expect_message (G_LOG_DOMAIN,
                       G_LOG_LEVEL_CRITICAL,
                       &quot;assertion*acquired_context*failed&quot;);
g_main_context_push_thread_default (bad_context);
g_test_assert_expected_messages ();
```

Note that you cannot use this to test [func@GLib.error] messages, since
[func@GLib.error] intentionally never returns even if the program doesn’t
abort; use [func@GLib.test_trap_subprocess] in this case.

If messages at [flags@GLib.LogLevelFlags.LEVEL_DEBUG] are emitted, but not explicitly
expected via [func@GLib.test_expect_message] then they will be ignored.&lt;/doc&gt;

other tests to malfunction.

Calling this function will not stop the test from running, you
need to return from the test function yourself. So you can
produce additional diagnostic messages or even continue running
the test.

If not called from inside a test, this function does nothing.

Note that unlike g_test_skip() and g_test_incomplete(), this
function does not log a message alongside the test failure.
If details of the test failure are available, either log them with
g_test_message() before g_test_fail(), or use g_test_fail_printf()
instead.&lt;/doc&gt;

This is the same as g_test_build_filename() with two differences.
The first difference is that you must only use this function from within
a testcase function.  The second difference is that you need not free
the return value — it will be automatically freed when the testcase
finishes running.

It is safe to use this function from a thread inside of a testcase
but you must ensure that all such uses occur before the main testcase
function returns (ie: it is best to ensure that all threads have been
joined).&lt;/doc&gt;

This function returns a valid string only within a test function.

Note that this is a test path, not a file system path.&lt;/doc&gt;

test random number generator, the name for g_get_prgname()
and parsing test related command line args.

This should be called before calling any other `g_test_*()` functions.

So far, the following arguments are understood:

- `-l`: List test cases available in a test executable.
- `--seed=SEED`: Provide a random seed to reproduce test
  runs using random numbers.
- `--verbose`: Run tests verbosely.
- `-q`, `--quiet`: Run tests quietly.
- `-p PATH`: Execute all tests matching the given path.
- `-s PATH`: Skip all tests matching the given path.
  This can also be used to force a test to run that would otherwise
  be skipped (ie, a test whose name contains &quot;/subprocess&quot;).
- `-m {perf|slow|thorough|quick|undefined|no-undefined}`: Execute tests according to these test modes:

  `perf`: Performance tests, may take long and report results (off by default).

  `slow`, `thorough`: Slow and thorough tests, may take quite long and maximize coverage
  (off by default).

  `quick`: Quick tests, should run really quickly and give good coverage (the default).

  `undefined`: Tests for undefined behaviour, may provoke programming errors
  under g_test_trap_subprocess() or g_test_expect_message() to check
  that appropriate assertions or warnings are given (the default).

  `no-undefined`: Avoid tests for undefined behaviour

- `--debug-log`: Debug test logging output.

Options which can be passed to @... are:

 - `&quot;no_g_set_prgname&quot;`: Causes g_test_init() to not call g_set_prgname().
 - %G_TEST_OPTION_ISOLATE_DIRS: Creates a unique temporary directory for each
   unit test and uses g_set_user_dirs() to set XDG directories to point into
   that temporary directory for the duration of the unit test. See the
   documentation for %G_TEST_OPTION_ISOLATE_DIRS.

Since 2.58, if tests are compiled with `G_DISABLE_ASSERT` defined,
g_test_init() will print an error and exit. This is to prevent no-op tests
from being executed, as g_assert() is commonly (erroneously) used in unit
tests, and is a no-op when compiled with `G_DISABLE_ASSERT`. Ensure your
tests are compiled without `G_DISABLE_ASSERT` defined.&lt;/doc&gt;

           line=&quot;803&quot;&gt;Installs a non-error fatal log handler which can be
used to decide whether log messages which are counted
as fatal abort the program.

The use case here is that you are running a test case
that depends on particular libraries or circumstances
and cannot prevent certain known critical or warning
messages. So you install a handler that compares the
domain and message to precisely not abort in such a case.

Note that the handler is reset at the beginning of
any test case, so you have to set it inside each test
function which needs the special behavior.

This handler has no effect on g_error messages.

This handler also has no effect on structured log messages (using
[func@GLib.log_structured] or [func@GLib.log_structured_array]). To change the fatal
behaviour for specific log messages, programs must install a custom log
writer function using [func@GLib.log_set_writer_func].See
[Using Structured Logging](logging.html#using-structured-logging).&lt;/doc&gt;

This is most useful to auto destroy allocated test resources at the end of a
test run. Resources are released in reverse queue order, that means
enqueueing callback `A` before callback `B` will cause `B()` to be called
before `A()` during teardown.&lt;/doc&gt;

with g_test_get_root(). Similar to g_test_run_suite(), the test
cases to be run are filtered according to test path arguments
(`-p testpath` and `-s testpath`) as parsed by g_test_init().
g_test_run_suite() or g_test_run() may only be called once in a
program.

In general, the tests and sub-suites within each suite are run in
the order in which they are defined. However, note that prior to
GLib 2.36, there was a bug in the `g_test_add_*`
functions which caused them to create multiple suites with the same
name, meaning that if you created tests &quot;/foo/simple&quot;,
&quot;/bar/simple&quot;, and &quot;/foo/using-bar&quot; in that order, they would get
run in that order (since g_test_run() would run the first &quot;/foo&quot;
suite, then the &quot;/bar&quot; suite, then the second &quot;/foo&quot; suite). As of
2.36, this bug is fixed, and adding the tests in that order would
result in a running order of &quot;/foo/simple&quot;, &quot;/foo/using-bar&quot;,
&quot;/bar/simple&quot;. If this new ordering is sub-optimal (because it puts
more-complicated tests before simpler ones, making it harder to
figure out exactly what has failed), you can fix it by changing the
test paths to group tests by suite in a way that will result in the
desired running order. Eg, &quot;/simple/foo&quot;, &quot;/simple/bar&quot;,
&quot;/complex/foo-using-bar&quot;.

However, you should never make the actual result of a test depend
on the order that tests are run in. If you need to ensure that some
particular code runs before or after a given test case, use
g_test_add(), which lets you specify setup and teardown functions.

If all tests are skipped or marked as incomplete (expected failures),
this function will return 0 if producing TAP output, or 77 (treated
as &quot;skip test&quot; by Automake) otherwise.&lt;/doc&gt;

           line=&quot;3888&quot;&gt;Respawns the test program to run only @test_path in a subprocess with the
given @envp environment.

This can be used for a test case that might not return, or that
might abort.

If @test_path is %NULL then the same test is re-run in a subprocess.
You can use g_test_subprocess() to determine whether the test is in
a subprocess or not.

@test_path can also be the name of the parent test, followed by
&quot;`/subprocess/`&quot; and then a name for the specific subtest (or just
ending with &quot;`/subprocess`&quot; if the test only has one child test);
tests with names of this form will automatically be skipped in the
parent process.

If @envp is %NULL, the parent process’ environment will be inherited.

If @usec_timeout is non-0, the test subprocess is aborted and
considered failing if its run time exceeds it.

The subprocess behavior can be configured with the
#GTestSubprocessFlags flags.

You can use methods such as g_test_trap_assert_passed(),
g_test_trap_assert_failed(), and g_test_trap_assert_stderr() to
check the results of the subprocess. (But note that
g_test_trap_assert_stdout() and g_test_trap_assert_stderr()
cannot be used if @test_flags specifies that the child should
inherit the parent stdout/stderr.)

If your `main ()` needs to behave differently in
the subprocess, you can call g_test_subprocess() (after calling
g_test_init()) to see whether you are in a subprocess.

Internally, this function tracks the child process using
g_child_watch_source_new(), so your process must not ignore `SIGCHLD`, and
must not attempt to watch or wait for the child process via another
mechanism.

The following example tests that calling
`my_object_new(1000000)` will abort with an error
message.

in tests that use g_test_init(), the option `-m no-undefined` disables
those tests, while `-m undefined` explicitly enables them (normally
the default behaviour).

[AddressSanitizer](https://github.com/google/sanitizers/wiki/AddressSanitizer)

If another thread is waiting for us using g_thread_join() then the
waiting thread will be woken up and get @retval as the return value
of g_thread_join().

Calling g_thread_exit() with a parameter @retval is equivalent to
returning @retval from the function @func, as given to g_thread_new().

You must only call g_thread_exit() from a thread that you created
yourself with g_thread_new() or related APIs. You must not call
this function from a thread created with another threading library
or or from within a #GThreadPool.&lt;/doc&gt;

Since version 2.32, GLib does not support custom thread implementations
anymore and the @vtable parameter is ignored and you should pass %NULL.

&amp;lt;note&amp;gt;&amp;lt;para&amp;gt;g_thread_init() must not be called directly or indirectly

priority, %G_PRIORITY_DEFAULT.

The given @function is called repeatedly until it returns %G_SOURCE_REMOVE
or %FALSE, at which point the timeout is automatically destroyed and the
function will not be called again. The first call to the function will be
at the end of the first @interval.

Note that timeout functions may be delayed, due to the processing of other
event sources. Thus they should not be relied on for precise timing.
After each call to the timeout function, the time of the next
timeout is recalculated based on the current time and the given interval
(it does not try to &#039;catch up&#039; time lost in delays).

See [memory management of sources][mainloop-memory-management] for details
on how to handle the return value and memory management of @data.

If you want to have a timer in the &quot;seconds&quot; range and do not care
about the exact time of the first call of the timer, use the
g_timeout_add_seconds() function; this function allows for more
optimizations and more efficient system power usage.

This internally creates a main loop source using g_timeout_source_new()
and attaches it to the global #GMainContext using g_source_attach(), so
the callback will be invoked in whichever thread is running that main
context. You can do these steps manually if you need greater control or to
use a custom main context.

It is safe to call this function from any thread.

The function is called repeatedly until it returns %G_SOURCE_REMOVE
or %FALSE, at which point the timeout is automatically destroyed and
the function will not be called again.

Unlike g_timeout_add(), this function operates at whole second granularity.
The initial starting point of the timer is determined by the implementation
and the implementation is expected to group multiple timers together so that
they fire all at the same time. To allow this grouping, the @interval to the
first timer is rounded and can deviate up to one second from the specified
interval. Subsequent timer iterations will generally run at the specified
interval.

Note that timeout functions may be delayed, due to the processing of other
event sources. Thus they should not be relied on for precise timing.
After each call to the timeout function, the time of the next
timeout is recalculated based on the current time and the given @interval

See [memory management of sources][mainloop-memory-management] for details
on how to handle the return value and memory management of @data.

If you want timing more precise than whole seconds, use g_timeout_add()
instead.

The grouping of timers to fire at the same time results in a more power
and CPU efficient behavior so if your timer is in multiples of seconds
and you don&#039;t require the first timer exactly one second from now, the
use of g_timeout_add_seconds() is preferred over g_timeout_add().

This internally creates a main loop source using
g_timeout_source_new_seconds() and attaches it to the main loop context
using g_source_attach(). You can do these steps manually if you need
greater control.

This function includes algorithmic Hangul Jamo composition,
but it is not exactly the inverse of g_unichar_decompose().
No composition can have either of @a or @b equal to zero.
To be precise, this function composes if and only if
there exists a Primary Composite P which is canonically
equivalent to the sequence &amp;lt;@a,@b&amp;gt;.  See the Unicode
Standard for the definition of Primary Composite.

If @a and @b do not compose a new character, @ch is set to zero.

Unicode canonical decomposition algorithm.

This function does not include compatibility
decompositions. It does, however, include algorithmic
Hangul Jamo decomposition, as well as &#039;singleton&#039;
decompositions which replace a character by a single
other character. In the case of singletons *@b will
be set to zero.

If @ch is not decomposable, *@a is set to @ch and *@b
is set to zero.

Note that the way Unicode decomposition pairs are
defined, it is guaranteed that @b would not decompose
further, but @a may itself decompose.  To get the full
canonical decomposition for @ch, one would need to
recursively call this function on @a.  Or use
g_unichar_fully_decompose().

pass %TRUE for @compat; for canonical decomposition
pass %FALSE for @compat.

The decomposed sequence is placed in @result.  Only up to
@result_len characters are written into @result.  The length
of the full decomposition (irrespective of @result_len) is
returned by the function.  For canonical decomposition,
currently all decompositions are of length at most 4, but
this may change in the future (very unlikely though).
At any rate, Unicode does guarantee that a buffer of length
18 is always enough for both compatibility and canonical
decompositions, so that is the size recommended. This is provided
as %G_UNICHAR_MAX_DECOMPOSITION_LENGTH.

the converse is not necessarily true. See the

If a character passes the g_unichar_iswide() test then it will also pass
this test, but not the other way around.  Note that some characters may
pass both this test and g_unichar_iszerowidth().&lt;/doc&gt;

A typical use of this function is with one of g_unichar_iswide() or
g_unichar_iswide_cjk() to determine the number of cells a string occupies
when displayed on a grid display (terminals).  However, note that not all
terminals support zero-width rendering of zero-width marks.&lt;/doc&gt;

you wanted to configure `O_NONBLOCK` then that had to be done separately with
`fcntl()`.

Since GLib 2.80, the constants %G_UNIX_PIPE_END_READ and
%G_UNIX_PIPE_END_WRITE can be used as mnemonic indexes in @fds.

It is a programmer error to call this function with unsupported flags, and a
critical warning will be raised.

As of GLib 2.78, it is preferred to pass `O_CLOEXEC` in, rather than
`FD_CLOEXEC`, as that matches the underlying `pipe()` API more closely. Prior
to 2.78, only `FD_CLOEXEC` was supported. Support for `FD_CLOEXEC` may be
deprecated and removed in future.&lt;/doc&gt;

signal @signum.  In GLib versions before 2.36, only `SIGHUP`, `SIGINT`,
`SIGTERM` can be monitored.  In GLib 2.36, `SIGUSR1` and `SIGUSR2`
were added. In GLib 2.54, `SIGWINCH` was added.

Note that unlike the UNIX default, all sources which have created a
watch will be dispatched, regardless of which underlying thread
invoked g_unix_signal_source_new().

For example, an effective use of this function is to handle `SIGTERM`
cleanly; flushing any outstanding files, and then calling
g_main_loop_quit().  It is not safe to do any of this from a regular
UNIX signal handler; such a handler may be invoked while malloc() or
another library function is running, causing reentrancy issues if the
handler attempts to use those functions.  None of the GLib/GObject
API is safe against this kind of reentrancy.

The interaction of this source when combined with native UNIX
functions like sigprocmask() is not defined.

The source will not initially be associated with any #GMainContext
and must be added to one with g_source_attach() before it will be
executed.&lt;/doc&gt;

Note that on some systems, when variables are overwritten, the

You should be mindful of the fact that environment variable handling
in UNIX is not thread-safe, and your program may crash if one thread
calls g_unsetenv() while another thread is calling getenv(). (And note
that many functions, such as gettext(), call getenv() internally.) This
function is only safe to use at the very start of your program, before
creating any other threads (or creating objects that create worker
threads of their own).

If you need to set up the environment for a child process, you can
use g_get_environ() to get an environment array, modify that with
g_environ_setenv() and g_environ_unsetenv(), and then pass that
array directly to execvpe(), g_spawn_async(), or the like.&lt;/doc&gt;

           line=&quot;2272&quot;&gt;Many URI schemes include one or more attribute/value pairs as part of the URI
value. This method can be used to parse them into a hash table. When an
attribute has multiple occurrences, the last value is the final returned
value. If you need to handle repeated attributes differently, use
#GUriParamsIter.

The @params string is assumed to still be `%`-encoded, but the returned
values will be fully decoded. (Thus it is possible that the returned values
may contain `=` or @separators, if the value was encoded in the input.)
Invalid `%`-encoding is treated as with the %G_URI_FLAGS_PARSE_RELAXED
rules for g_uri_parse(). (However, if @params is the path or query string
from a #GUri that was parsed without %G_URI_FLAGS_PARSE_RELAXED and
%G_URI_FLAGS_ENCODED, then you already know that it does not contain any
invalid encoding.)

%G_URI_PARAMS_WWW_FORM is handled as documented for g_uri_params_iter_init().

If %G_URI_PARAMS_CASE_INSENSITIVE is passed to @flags, attributes will be
compared case-insensitively, so a params string `attr=123&amp;amp;Attr=456` will only
return a single attribute–value pair, `Attr=456`. Case will be preserved in
the returned attributes.

If @params cannot be parsed (for example, it contains two @separators
characters in a row), then @error is set and %NULL is returned.&lt;/doc&gt;

returned as %NULL (but note that all URIs always have a path component,
though it may be the empty string).

If @flags contains %G_URI_FLAGS_ENCODED, then `%`-encoded characters in
@uri_ref will remain encoded in the output strings. (If not,
then all such characters will be decoded.) Note that decoding will
only work if the URI components are ASCII or UTF-8, so you will
need to use %G_URI_FLAGS_ENCODED if they are not.

Note that the %G_URI_FLAGS_HAS_PASSWORD and
%G_URI_FLAGS_HAS_AUTH_PARAMS @flags are ignored by g_uri_split(),
since it always returns only the full userinfo; use
g_uri_split_with_user() if you want it split up.&lt;/doc&gt;

compare the keys with strcmp() when sorting instead of sorting

sequences, the result is undefined. This can happen if the strings are in

In order to sort filenames correctly, this function treats the dot &#039;.&#039;
as a special case. Most dictionary orderings seem to consider it
insignificant, thus producing the ordering &quot;event.c&quot; &quot;eventgenerator.c&quot;
&quot;event.h&quot; instead of &quot;event.c&quot; &quot;event.h&quot; &quot;eventgenerator.c&quot;. Also, we
would like to treat numbers intelligently so that &quot;file1&quot; &quot;file10&quot; &quot;file5&quot;
is sorted as &quot;file1&quot; &quot;file5&quot; &quot;file10&quot;.

           line=&quot;496&quot;&gt;Converts a string into canonical form, standardizing
such issues as whether a character with an accent
is represented as a base character and combining
accent or as a single precomposed character. The
string has to be valid UTF-8, otherwise %NULL is
returned. You should generally call g_utf8_normalize()
before comparing two Unicode strings.

The normalization mode %G_NORMALIZE_DEFAULT only
standardizes differences that do not affect the
text content, such as the above-mentioned accent
representation. %G_NORMALIZE_ALL also standardizes
the &quot;compatibility&quot; characters in Unicode, such
as SUPERSCRIPT THREE to the standard forms
(in this case DIGIT THREE). Formatting information
may be lost but for most text operations such
characters should be considered the same.

%G_NORMALIZE_DEFAULT_COMPOSE and %G_NORMALIZE_ALL_COMPOSE
are like %G_NORMALIZE_DEFAULT and %G_NORMALIZE_ALL,
but returned a result with composed forms rather
than a maximally decomposed form. This is often
useful if you intend to convert the string to
a legacy encoding or pass it to a system with
less capable Unicode handling.&lt;/doc&gt;

Since 2.10, this function allows to pass a negative @offset to
step backwards. It is usually worth stepping backwards from the end
instead of forwards if @offset is in the last fourth of the string,
since moving forward is about 3 times faster than moving backward.

Note that this function doesn&#039;t abort when reaching the end of @str.
Therefore you should be sure that @offset is within string boundaries
before calling that function. Call g_utf8_strlen() when unsure.
This limitation exists as this function is called frequently during
text rendering and therefore has to be as fast as possible.&lt;/doc&gt;

If @end is non-%NULL, then the end of the valid range

Note that g_utf8_validate() returns %FALSE if @max_len is
positive and any of the @max_len bytes are nul.

Returns %TRUE if all of @str was valid. Many GLib and GTK
routines require valid UTF-8 as input; so data read from a file

doing anything else with it.&lt;/doc&gt;

           line=&quot;2483&quot;&gt;Parses a #GVariant from a text representation.

A single #GVariant is parsed from the content of @text.

The format is described [here](gvariant-text-format.html).

The memory at @limit will never be accessed and the parser behaves as
if the character at @limit is the nul terminator.  This has the
effect of bounding @text.

If @endptr is non-%NULL then @text is permitted to contain data
following the value that this function parses and @endptr will be
updated to point to the first character past the end of the text
parsed by this function.  If @endptr is %NULL and there is extra data
then an error is returned.

If @type is non-%NULL then the value will be parsed to have that
type.  This may result in additional parse errors (in the case that
the parsed value doesn&#039;t fit the type) but may also result in fewer
errors (in the case that the type would have been ambiguous, such as
with empty arrays).

In the event that the parsing is successful, the resulting #GVariant
is returned. It is never floating, and must be freed with
[method@GLib.Variant.unref].

In case of any error, %NULL will be returned.  If @error is non-%NULL
then it will be set to reflect the error that occurred.

Officially, the language understood by the parser is “any string
produced by [method@GLib.Variant.print]”. This explicitly includes
`g_variant_print()`’s annotated types like `int64 -1000`.

There may be implementation specific restrictions on deeply nested values,
which would result in a %G_VARIANT_PARSE_ERROR_RECURSION error. #GVariant is
guaranteed to handle nesting up to at least 64 levels.&lt;/doc&gt;

error within the string for which parsing was attempted.

The resulting string is suitable for output to the console or other
monospace media where newlines are treated in the usual way.

The message will typically look something like one of the following:

|[
unterminated string constant:
  (1, 2, 3, &#039;abc
            ^^^^
]|

or

|[
unable to find a common type:
  [1, 2, 3, &#039;str&#039;]
   ^        ^^^^^
]|

The format of the message may change in a future version.

@error must have come from a failed attempt to g_variant_parse() and
@source_str must be exactly the same string that caused the error.
If @source_str was not nul-terminated when you passed it to
g_variant_parse() then you must add nul termination before using this
function.&lt;/doc&gt;

This function is similar to [func@GLib.vsprintf], except that it allocates a
string to hold the output, instead of putting the output in a buffer
you allocate in advance.

The returned value in @string is guaranteed to be non-`NULL`, unless
@format contains `%lc` or `%ls` conversions, which can fail if no
multibyte representation is available for the given character.

to not exceed @n characters (including the terminating nul character), so
it is easy to ensure that a buffer overflow cannot occur.

See also [func@GLib.strdup_vprintf].

In versions of GLib prior to 1.2.3, this function may return -1 if the
output was truncated, and the truncated string may not be nul-terminated.
In versions prior to 1.3.12, this function returns the length of the output
string.

The return value of `g_vsnprintf()` conforms to the `vsnprintf()` function
as standardized in ISO C99. Note that this is different from traditional
`vsnprintf()`, which returns the length of the output string.

The format string may contain positional parameters, as specified in
the Single Unix Specification.&lt;/doc&gt;

    &lt;function-macro name=&quot;warning&quot; c:identifier=&quot;g_warning&quot; introspectable=&quot;0&quot;&gt;
      &lt;doc xml:space=&quot;preserve&quot;
           filename=&quot;glib/gmessages.c&quot;
           line=&quot;194&quot;&gt;A convenience function/macro to log a warning message.

The message should typically *not* be translated to the user’s language.

This is not intended for end user error reporting. Use of [type@GLib.Error] is
preferred for that instead, as it allows calling functions to perform actions
conditional on the type of error.

Warning messages are intended to be used in the event of unexpected
external conditions (system misconfiguration, missing files,
other trusted programs violating protocol, invalid contents in
trusted files, etc.)

If attempting to deal with programmer errors (for example, incorrect function
parameters) then you should use [flags@GLib.LogLevelFlags.LEVEL_CRITICAL] instead.

[func@GLib.warn_if_reached] and func@GLib.warn_if_fail] log at [flags@GLib.LogLevelFlags.LEVEL_WARNING].

You can make warnings fatal at runtime by setting the `G_DEBUG`
environment variable (see
[Running GLib Applications](glib-running.html)):

```
G_DEBUG=fatal-warnings gdb ./my-program
```

Any unrelated failures can be skipped over in
[gdb](https://www.gnu.org/software/gdb/) using the `continue` command.

If [func@GLib.log_default_handler] is used as the log handler function,
a newline character will automatically be appended to @..., and
need not be entered manually.

If structured logging is enabled, this will use [func@GLib.log_structured];
otherwise it will use [func@GLib.log]. See
[Using Structured Logging](logging.html#using-structured-logging).&lt;/doc&gt;

           filename=&quot;glib/gmessages.h&quot;
           line=&quot;481&quot;&gt;Logs a warning only once.

g_warning_once() calls g_warning() with the passed message the first time
the statement is executed; subsequent times it is a no-op.

Note! On platforms where the compiler doesn&#039;t support variadic macros, the
warning is printed each time instead of only once.&lt;/doc&gt;
