<doc xml:space="preserve">Sets the meta-data of application @name inside the list of
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: "\%f", which will
be expanded as the local file name retrieved from the bookmark's
URI; "\%u", which will be expanded as the bookmark's URI.
The expansion is done automatically when retrieving the stored
command line using the g_bookmark_file_get_app_info() function.
@count is the number of times the application has registered the
bookmark; if is &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

<doc xml:space="preserve">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.</doc>

<record name="Cond" c:type="GCond">
<doc xml:space="preserve">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:
|[&lt;!-- language="C" --&gt;
gpointer current_data = NULL;
GMutex data_mutex;
GCond data_cond;
void
push_data (gpointer data)
{
g_mutex_lock (&amp;data_mutex);
current_data = data;
g_cond_signal (&amp;data_cond);
g_mutex_unlock (&amp;data_mutex);
}
gpointer
pop_data (void)
{
gpointer data;
g_mutex_lock (&amp;data_mutex);
while (!current_data)
g_cond_wait (&amp;data_cond, &amp;data_mutex);
data = current_data;
current_data = NULL;
g_mutex_unlock (&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.</doc>

When this function returns, @mutex is locked again and owned by the

When using condition variables, it is possible that a spurious wakeup

not called). It'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.</doc>

<doc xml:space="preserve">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):
|[&lt;!-- language="C" --&gt;
gpointer
pop_data_timed (void)
{
gint64 end_time;
gpointer data;
g_mutex_lock (&amp;data_mutex);
end_time = g_get_monotonic_time () + 5 * G_TIME_SPAN_SECOND;
while (!current_data)
if (!g_cond_wait_until (&amp;data_cond, &amp;data_mutex, end_time))
{
// timeout has passed.
g_mutex_unlock (&amp;data_mutex);
return NULL;
}
// there is data for us
data = current_data;
current_data = NULL;
g_mutex_unlock (&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).</doc>

Works just like the platform's C library strftime() function,

(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's C library.
For example, don'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.</doc>

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

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

<method name="format" c:identifier="g_date_time_format" version="2.26">
<doc xml:space="preserve">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.
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)
- \%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 blank
- \%l: the hour (12-hour clock) as a decimal number (range 1 to 12);
single digits are preceded by a blank
- \%m: the month as a decimal number (range 01 to 12)
- \%M: the minute as a decimal number (range 00 to 59)
- \%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".
- \%P: like \%p but lowercase: "am" or "pm" or a corresponding string for
the current locale
- \%r: the time in a.m. or p.m. notation
- \%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.</doc>

@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.</doc>

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).
&lt;!-- FIXME: Need more here. --&gt; 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 'bucket' 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
vulerable 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.</doc>

A #GHmac can be used to compute the HMAC of a key and an

A #GHmac works by feeding a binary blob through g_hmac_update()

hexadecimal string; or g_hmac_get_digest(), which will return a

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.
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.</doc>

not require such a flush. For write-only channels, a call to

This includes the possibility of seeking with seek type %G_SEEK_CUR

<doc xml:space="preserve">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

c:identifier="g_main_context_push_thread_default"
version="2.22">
<doc xml:space="preserve">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 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't have control over how the new thread was created (e.g.
in the new thread isn'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().</doc>

<doc xml:space="preserve">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 "one
last access" 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.
|[&lt;!-- language="C" --&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-&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:
|[&lt;!-- language="C" --&gt;
void
start_counting (GMarkupParseContext *context)
{
CounterData *data = g_slice_new (CounterData);
data-&gt;tag_count = 0;
g_markup_parse_context_push (context, &amp;counter_subparser, data);
}
gint
end_counting (GMarkupParseContext *context)
{
CounterData *data = g_markup_parse_context_pop (context);
int result;
result = data-&gt;tag_count;
g_slice_free (CounterData, data);
return result;
}
]|
The subparser would then be used as follows:
|[&lt;!-- language="C" --&gt;
static void start_element (context, element_name, ...)
{
if (strcmp (element_name, "count-these") == 0)
start_counting (context);
// else, handle other tags...
}
static void end_element (context, element_name, ...)
{
if (strcmp (element_name, "count-these") == 0)
g_print ("Counted %d tags\n", end_counting (context));
// else, handle other tags...

<doc xml:space="preserve">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
"^\d?\d(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)\d\d$".
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.</doc>

<union name="Mutex" c:type="GMutex">
<doc xml:space="preserve">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:
|[&lt;!-- language="C" --&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'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:
|[&lt;!-- language="C" --&gt;
int
give_me_next_number (void)
{
static GMutex mutex;
static int current_number = 0;
int ret_val;
g_mutex_lock (&amp;mutex);
ret_val = current_number = calc_next_number (current_number);
g_mutex_unlock (&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.</doc>

In strict POSIX mode, the first non-argument parameter encountered

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 "ls foo -l". With GNU style parsing, this
will list "foo" in long mode. In strict POSIX style, this will list
the files named "foo" and "-l".
It may be useful to force strict POSIX mode when creating "verb
style" command line tools. For example, the "gsettings" command line
tool supports the global option "--schemadir" as well as many
subcommands ("get", "set", 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).</doc>

<record name="RWLock" c:type="GRWLock" version="2.32">
<doc xml:space="preserve">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 ('reader') and full ('writer') access. While only
one thread at a time is allowed write access (by holding the 'writer'
lock via g_rw_lock_writer_lock()), multiple threads can gain
simultaneous read-only access (by holding the 'reader' lock via
g_rw_lock_reader_lock()).
Here is an example for an array with access functions:
|[&lt;!-- language="C" --&gt;
GRWLock lock;
GPtrArray *array;
gpointer
my_array_get (guint index)
{
gpointer retval = NULL;
if (!array)
return NULL;
g_rw_lock_reader_lock (&amp;lock);
if (index &lt; array-&gt;len)
retval = g_ptr_array_index (array, index);
g_rw_lock_reader_unlock (&amp;lock);
return retval;
}
void
my_array_set (guint index, gpointer data)
{
g_rw_lock_writer_lock (&amp;lock);
if (!array)
array = g_ptr_array_new ();
if (index &gt;= array-&gt;len)
g_ptr_array_set_size (array, index+1);
g_ptr_array_index (array, index) = data;
g_rw_lock_writer_unlock (&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.</doc>

glib:get-type="g_regex_get_type"
c:symbol-prefix="regex">
<doc xml:space="preserve">The g_regex_*() functions implement regular
expression pattern matching using syntax and semantics similar to
Perl regular expression.
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 "\Biss\B" which finds occurrences of "iss"
in the middle of words. ("\B" matches only if the current position in the
subject is not a word boundary.) When applied to the string "Mississipi"
from the fourth byte, namely "issipi", it does not match, because "\B" 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 "iss" 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,
"\xc3\xa0" (i.e. "à") 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 "\xc3\xa0" is two
bytes and two characters long.
When matching a pattern, "\n" matches only against a "\n" character in
the string, and "\r" matches only a "\r" character. To match any newline
sequence use "\R". This particular group matches either the two-character
sequence CR + LF ("\r\n"), or one of the single characters LF (linefeed,
U+000A, "\n"), VT vertical tab, U+000B, "\v"), FF (formfeed, U+000C, "\f"),
CR (carriage return, U+000D, "\r"), 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 "\R"). 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 "#" outside a character class is encountered. This indicates
a comment that lasts until after the next newline.
When setting the %G_REGEX_JAVASCRIPT_COMPAT flag, pattern syntax and pattern
matching is changed to be compatible with the way that regular expressions
work in JavaScript. More precisely, a lonely ']' character in the pattern
is a syntax error; the '\x' escape only allows 0 to 2 hexadecimal digits, and
you must use the '\u' escape sequence with 4 hex digits to specify a unicode
codepoint instead of '\x' or 'x{....}'. If '\x' or '\u' are not followed by
the specified number of hex digits, they match 'x' and 'u' literally; also
'\U' always matches 'U' instead of being an error in the pattern. Finally,
pattern matching is modified so that back references to an unset subpattern
group produces a match with the empty string instead of an error. See
pcreapi(3) for more information.
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.</doc>

<doc xml:space="preserve">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
"&lt;a&gt; &lt;b&gt; &lt;c&gt;" against the pattern "&lt;.*&gt;"
you get "&lt;a&gt; &lt;b&gt; &lt;c&gt;".
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
"&lt;a&gt; &lt;b&gt; &lt;c&gt;" against the pattern "&lt;.*&gt;;"
you would obtain three matches: "&lt;a&gt; &lt;b&gt; &lt;c&gt;",
"&lt;a&gt; &lt;b&gt;" and "&lt;a&gt;".
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 "\b".

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

As a special case, the result of splitting the empty string "" is an

this special case is that being able to represent a empty vector is
typically more useful than consistent handling of empty elements. If

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

function also returns a timeout value of 0 to ensure that the poll() call
doesn'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'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'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.</doc>

<callback name="SpawnChildSetupFunc" c:type="GSpawnChildSetupFunc">
<doc xml:space="preserve">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'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'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.</doc>

<doc xml:space="preserve">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.
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.
@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.

<doc xml:space="preserve">Creates a #GTimeZone corresponding to @identifier.
@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 "Pacific Standard Time".
Valid RFC3339 time offsets are `"Z"` (for UTC) or
`"±hh:mm"`. ISO 8601 additionally specifies
`"±hhmm"` and `"±hh"`. 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, or string in
"std offset [dst [offset],start[/time],end[/time]]" (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
`"[±]hh[[:]mm[:ss]]"`. Dates are either
`"Jn"` (Julian day with n between 1 and 365, leap
years not counted), `"n"` (zero-based Julian day
with n between 0 and 365) or `"Mm.w.d"` (day d
(0 &lt;= d &lt;= 6) of week w (1 &lt;= w &lt;= 5) of month m (1 &lt;= m &lt;= 12), day
0 is a Sunday). Times are in local wall clock time, the default is
02:00:00.
In Windows, the "tzn[+|–]hh[:mm[:ss]][dzn]" 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

<doc xml:space="preserve">#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 DBus, or when saving settings using GSettings.
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:
|[&lt;!-- language="C" --&gt;
GVariant *v = g_variant_new ('u', 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-pointers].
The range of possible values is determined by the type.
The type system used by #GVariant is #GVariantType.
#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 g_variant_ref() and
g_variant_unref(). #GVariant also has floating reference counts --
see g_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 serialised
form. It works particularly well with data located in memory-mapped
files. It can perform nearly all deserialisation operations in a
small constant time, usually touching only a single memory page.
Serialised #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 #GVariantType for
exceptions. (However, #GVariant's serialisation format is not the same
as the serialisation format of a D-Bus message body: use #GDBusMessage,
in the gio library, for those.)
For space-efficiency, the #GVariant serialisation 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 #GMappedFile, and call g_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 serialised data, memory for the type
information cache, buffer management memory and memory for the
#GVariant structure itself.
## Serialised Data Memory
This is the memory that is used for storing GVariant data in
serialised 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 serialisation.
If we add an item "width" that maps to the int32 value of 500 then
we will use 4 byte 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 deserialisation.
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 malloc 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 malloc 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 #GHashTable to
store and lookup 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 serialised 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 g_free() or a g_slice_free() or
even g_mapped_file_unref().
One buffer management structure is used for each chunk of
serialised 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
serialised 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 g_variant_unref()). The
type information is shared. The serialised data and the buffer
management structure for that serialised 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 byes of memory
for the serialised data, 16 bytes for buffer management and 24
bytes for the #GVariant instance, or a total of 160 bytes, plus
malloc overhead. If we were to use g_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 serialised data and buffer
management for those dictionaries, but the type information would
be shared.</doc>

@format must be a text format #GVariant with one extension: at any
point that a value may appear in the text, a '%' 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:
|[&lt;!-- language="C" --&gt;
g_variant_new_parsed ("[('one', 1), ('two', %i), (%s, 3)]", 2, "three");
]|
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
|[&lt;!-- language="C" --&gt;
[('one', 1), ('two', 2), ('three', 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 "%*", "%?", "\%r", or anything starting

<doc xml:space="preserve">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 "(ii)"). In the case
that the format_string was '*', '?', 'r', or a format starting with
'@' 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

If @value is a fixed-sized value that was deserialised from a

To deserialise the data returned by this function, in addition to the

machine might be different) the endianness of the machine that stored
it. As a result, file formats or network messages that incorporate

<doc xml:space="preserve">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,

names starting with `g_variant_new_` return floating

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 "assumes
ownership" 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.</doc>

<doc xml:space="preserve">If @value is floating, sink it. Otherwise, do nothing.
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's callback allows
the user to do whichever is more convenient for them. The caller
will alway 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.</doc>

<doc xml:space="preserve">#GVariantDict is a mutable interface to #GVariant dictionaries.
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 "count" 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.

<doc xml:space="preserve">Gets the next item in the container and unpacks it into the variable

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():
|[&lt;!-- language="C" --&gt;
// Iterates a dictionary of type 'a{sv}'
void
iterate_dictionary (GVariant *dictionary)
{
GVariantIter iter;
GVariant *value;
gchar *key;
g_variant_iter_init (&amp;iter, dictionary);
while (g_variant_iter_loop (&amp;iter, "{sv}", &amp;key, &amp;value))
{
g_print ("Item '%s' has type '%s'\n", key,
g_variant_get_type_string (value));
// no need to free 'key' and 'value' 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 '&amp;' 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.

<doc xml:space="preserve">This section introduces the GVariant 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 GVariant.
The first major change with respect to the D-Bus type system is the
introduction of maybe (or "nullable") types. Any type in GVariant 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 GVariant 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 GVariant, 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, GVariant types are described with strings ("type
strings"). Subject to the differences mentioned above, these strings
are of the same form as those found in DBus. 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. GVariant deals with single values directly so GVariant type
strings always describe the type of exactly one value. This means
that a D-Bus signature string is generally not a valid GVariant 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,
g_variant_get_type() will never return an indefinite type, but
calling g_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 #GtkBin can exist (since #GtkBin is an abstract class),
but a #GtkWindow can certainly be instantiated, and you would say
that the #GtkWindow is a #GtkBin (since #GtkWindow is a subclass of
#GtkBin).
## GVariant Type Strings
A GVariant 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
g_variant_type_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)}))".
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_STRING; 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.</doc>

deprecated="1"
deprecated-version="2.32">
<doc xml:space="preserve">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's best to avoid
calling g_atexit() (or atexit()) except in the main executable of a
program.</doc>

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) / 72 + 1 bytes of extra space.
@break_lines is typically used when putting base64-encoded data in emails.
It breaks the lines at 72 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.</doc>

<doc xml:space="preserve">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 "C" or any English locales (those
starting with "en_")
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.</doc>

If a file called @filename already exists it will be overwritten.
This write is atomic in the sense that it is first written to a temporary

- 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 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.

will return %TRUE if the file exists; the check whether it's a
directory doesn't matter since the existence test is %TRUE. With
the current set of available tests, there'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.
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't work!

// DON'T DO THIS
if (!g_file_test (filename, G_FILE_TEST_IS_SYMLINK))

]|
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'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.</doc>

The first character set from the @charsets is the filename encoding, the

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 "\@locale" 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.

Before version 2.36 this function would ignore the `HOME` environment

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't wish to increase your GLib

prints a new-line character after the message, so one does not need to be

The behavior of this log handler can be influenced by a number of
environment variables:

- `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.
stderr is used for levels %G_LOG_LEVEL_ERROR, %G_LOG_LEVEL_CRITICAL,
%G_LOG_LEVEL_WARNING and %G_LOG_LEVEL_MESSAGE. stdout is used for
the rest.

Note that since the #G_LOG_LEVEL_ERROR log level is always fatal, if
you want to set a handler for this log level you must combine it with
#G_LOG_FLAG_FATAL.
This has no effect if structured logging is enabled; see
[Using Structured Logging][using-structured-logging].
Here is an example for adding a log handler for all warning messages
in the default domain:
|[&lt;!-- language="C" --&gt;
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+:
|[&lt;!-- language="C" --&gt;
g_log_set_handler ("Gtk", 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:
|[&lt;!-- language="C" --&gt;
g_log_set_handler ("GLib", G_LOG_LEVEL_MASK | G_LOG_FLAG_FATAL
| G_LOG_FLAG_RECURSION, my_log_handler, NULL);

<doc xml:space="preserve">Log a message with structured data. The message will be passed through to
the log writer set by the application using g_log_set_writer_func(). If the
message is fatal (i.e. its log level is %G_LOG_LEVEL_ERROR), the program will
be aborted at the end of this function.
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 g_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.
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, G_DEBUG_HERE(), g_message(), g_warning(), g_critical(),
g_error(), etc, if the symbols `G_LOG_USE_STRUCTURED` is defined before including
glib.h.
For example:
|[&lt;!-- language="C" --&gt;
g_log_structured (G_LOG_DOMAIN, G_LOG_LEVEL_DEBUG,
"MESSAGE_ID", "06d4df59e6c24647bfe69d2c27ef0b4e",
"MY_APPLICATION_CUSTOM_FIELD", "some debug string",
"MESSAGE", "This is a debug message about pointer %p and integer %u.",
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 g_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:
|[&lt;!-- language="C" --&gt;
const GLogField fields[] = {
{ "MESSAGE", "This is a debug message.", -1 },
{ "MESSAGE_ID", "fcfb2e1e65c3494386b74878f1abf893", -1 },
{ "MY_APPLICATION_CUSTOM_FIELD", "some debug string", -1 },
{ "MY_APPLICATION_STATE", 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.</doc>

<function name="main_depth" c:identifier="g_main_depth">
<doc xml:space="preserve">Returns the depth of the stack of calls to
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 "garbage collected" system.
|[&lt;!-- language="C" --&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-&gt;next);
g_free (l-&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't work, since the idle function could be called from a
recursive callback. This can be fixed by using g_main_depth()
|[&lt;!-- language="C" --&gt;
gpointer
allocate_memory (gsize size)
{
FreeListBlock *block = g_new (FreeListBlock, 1);
block-&gt;mem = g_malloc (size);
block-&gt;depth = g_main_depth ();
free_list = g_list_prepend (free_list, block);
return block-&gt;mem;
}
void
free_allocated_memory (void)
{
GList *l;
int depth = g_main_depth ();
for (l = free_list; l; );
{
GList *next = l-&gt;next;
FreeListBlock *block = l-&gt;data;
if (block-&gt;depth &gt; depth)
{
g_free (block-&gt;mem);
g_free (block);
free_list = g_list_delete_link (free_list, l);
}
l = next;
}
}

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'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'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'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.</doc>

This utility function is not required to write a parser but can save

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 "supported" 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
attributes (of type %G_MARKUP_ERROR_INVALID_CONTENT) as well
as parse errors for boolean-valued attributes (again of type

On POSIX systems, an absolute file name is well-defined. It always
starts from the single root directory. For example "/usr/local".
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 "\Users\tml" or begins with the root on a drive,
for example "C:\Windows". The first case also includes UNC paths
such as "\\myserver\docs\foo". 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 "D:foo/bar", 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.</doc>

Note that, if the user code will (possibly) match a string against a

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

This function is equivalent to g_regex_split() but it does

If this function is to be called on the same @pattern more than

As a special case, the result of splitting the empty string ""
is an empty vector, not a vector containing a single string.
The reason for this special case is that being able to represent
a empty vector is typically more useful than consistent handling
of empty elements. If you do need to represent empty elements,
you'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 "ab c" using as a separator
"\s*", you will get "a", "b" and "c".</doc>

used for the previous variables and its value isn'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.</doc>

throws="1">
<doc xml:space="preserve">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'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'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't use argument vectors, but a command line. The C runtime
library'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 of double quotes. The spawn*() functions
don'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's environment.
If @envp is %NULL, the child inherits its parent's environment.
@flags should be the bitwise OR of any flags you want to affect the
function's behaviour. The %G_SPAWN_DO_NOT_REAP_CHILD means that the
child will not automatically be reaped; you must use a child watch to
be notified about the death of the child process. 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().
%G_SPAWN_LEAVE_DESCRIPTORS_OPEN means that the parent's 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_STDOUT_TO_DEV_NULL means that the child's standard output
will be discarded, instead of going to the same location as the parent's
standard output. If you use this flag, @standard_output must be %NULL.
%G_SPAWN_STDERR_TO_DEV_NULL means that the child's standard error
will be discarded, instead of going to the same location as the parent's
standard error. If you use this flag, @standard_error must be %NULL.
%G_SPAWN_CHILD_INHERITS_STDIN means that the child will inherit the parent's
standard input (by default, the child's standard input is attached to
/dev/null). If you use this flag, @standard_input must be %NULL.
%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'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 @standard_input, @standard_output, @standard_error
locations will be filled with file descriptors for writing to the child'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't be created.
If @standard_input is NULL, the child's standard input is attached to
/dev/null unless %G_SPAWN_CHILD_INHERITS_STDIN is set.
If @standard_error is NULL, the child's standard error goes to the same
location as the parent's standard error unless %G_SPAWN_STDERR_TO_DEV_NULL
is set.
If @standard_output is NULL, the child's standard output goes to the same
location as the parent'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, @standard_input, @standard_output,
and @standard_error 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().
If you are writing a GTK+ application, and the program you
are spawning is a graphical application, too, then you may
want to use gdk_spawn_on_screen_with_pipes() instead to ensure that
the spawned program opens its windows on the right screen.</doc>

version="2.34"
throws="1">
<doc xml:space="preserve">Set @error if @exit_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 an
exit status for 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
@exit_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 exit status.
The @domain and @code of @error have special semantics in the case
where the process has an "exit code", as opposed to being killed by
a signal. On Unix, this happens if WIFEXITED() would be true of
@exit_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, 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 @exit_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.</doc>

<doc xml:space="preserve">A case-insensitive string comparison, corresponding to the standard

to g_strcasecmp() except it only compares the first @n characters of
the strings.</doc>
<doc-deprecated xml:space="preserve">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's broken if your string
is localized, since it doesn't work on many encodings at all,
including UTF-8, EUC-JP, etc.
There are therefore two replacement techniques: g_ascii_strncasecmp(),
which only works on ASCII and is not locale-sensitive, and
g_utf8_casefold() followed by strcmp() on the resulting strings,
which is good for case-insensitive sorting of UTF-8.</doc-deprecated>

API. See [Testing for Messages][testing-for-messages].
Use g_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 g_test_expect_message().)
For example:
|[&lt;!-- language="C" --&gt;
// 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,
"assertion*acquired_context*failed");
g_main_context_push_thread_default (bad_context);
g_test_assert_expected_messages ();
]|
Note that you cannot use this to test g_error() messages, since
g_error() intentionally never returns even if the program doesn't
abort; use g_test_trap_subprocess() in this case.
If messages at %G_LOG_LEVEL_DEBUG are emitted, but not explicitly
expected via g_test_expect_message() then they will be ignored.</doc>

The use case here is that you are running a test case

Note that the handler is reset at the beginning of

This handler has no effect on g_error messages.
This handler also has no effect on structured log messages (using
g_log_structured() or g_log_structured_array()). To change the fatal
behaviour for specific log messages, programs must install a custom log
writer function using g_log_set_writer_func().See

cases to be run are filtered according to test path arguments
(`-p 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 "/foo/simple",
"/bar/simple", and "/foo/using-bar" in that order, they would get
run in that order (since g_test_run() would run the first "/foo"
suite, then the "/bar" suite, then the second "/foo" suite). As of
2.36, this bug is fixed, and adding the tests in that order would
result in a running order of "/foo/simple", "/foo/using-bar",
"/bar/simple". 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, "/simple/foo", "/simple/bar",
"/complex/foo-using-bar".
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.

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
"`/subprocess/`" and then a name for the specific subtest (or just
ending with "`/subprocess`" if the test only has one child test);
tests with names of this form will automatically be skipped in the
parent process.
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.
The following example tests that calling
`my_object_new(1000000)` will abort with an error
message.

The function is called repeatedly until it returns %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't require the first timer exactly one second from now, the
use of g_timeout_add_seconds() is preferred over g_timeout_add().

A single #GVariant is parsed from the content of @text.
The format is described [here][gvariant-text].
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'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
g_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
