|
|
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 < 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,

<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:
|
|
|[<!-- language="C" -->
|
|
gpointer current_data = NULL;
|
|
GMutex data_mutex;
|
|
GCond data_cond;
|
|
|
|
void
|
|
push_data (gpointer data)
|
|
{
|
|
g_mutex_lock (&data_mutex);
|
|
current_data = data;
|
|
g_cond_signal (&data_cond);
|
|
g_mutex_unlock (&data_mutex);
|
|
}
|
|
|
|
gpointer
|
|
pop_data (void)
|
|
{
|
|
gpointer data;
|
|
|
|
g_mutex_lock (&data_mutex);
|
|
while (!current_data)
|
|
g_cond_wait (&data_cond, &data_mutex);
|
|
data = current_data;
|
|
current_data = NULL;
|
|
g_mutex_unlock (&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>

This is when g_cond_signal() is called, but another thread acquires

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

mentioned below.

Note that as #GDateTime "is oblivious to leap seconds", leap seconds information

`23:59:59`.

<sep> is the separator and can be either 'T', 't' or ' '. The latter two

separators are an extension from

|
[RFC 3339](https://tools.ietf.org/html/rfc3339#section-5.6).
|
|
|

<date> is in the form:

|
|
- `YYYYMMDD` - Same as above without dividers.

|
- `YYYY-DDD` - Ordinal day where DDD is from 001 to 366, e.g. 2016-237.
|
|
- `YYYYDDD` - Same as above without dividers.
|
|
- `YYYY-Www-D` - Week day where ww is from 01 to 52 and D from 1-7,
|
|
e.g. 2016-W34-3.
|
|
- `YYYYWwwD` - Same as above without dividers.
|
|
|
|
<time> is in the form:
|
|
|
|
- `hh:mm:ss(.sss)` - Hours, minutes, seconds (subseconds), e.g. 22:10:42.123.
|
|
- `hhmmss(.sss)` - Same as above without dividers.
|
|
|
|
<tz> is an optional timezone suffix of the form:
|
|
|
|
- `Z` - UTC.
|
|
- `+hh:mm` or `-hh:mm` - Offset from UTC in hours and minutes, e.g. +12:00.
|
|
- `+hh` or `-hh` - Offset from UTC in hours, e.g. +12.
|
|
|
|
If the timezone is not provided in @text it must be provided in @default_tz

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

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

|
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).

The first week of the year is week 1. This is the week that contains

the first Thursday of the year. Equivalently, this is the first week

that has more than 4 of its days falling within the calendar year.

The value 0 is never returned by this function. Days contained

within a year but occurring before the first ISO 8601 week of that

year are considered as being contained in the last week of the

previous year. Similarly, the final days of a calendar year may be

considered as being part of the first ISO 8601 week of the next year
|

if 4 or more days of that week are contained within the new year.</doc>

g_hash_table_new() when a #GHashTable is created.
|
|
|
|
The function is passed a key and should return a #guint hash value.
|
|
The functions g_direct_hash(), g_int_hash() and g_str_hash() provide
|
|
hash functions which can be used when the key is a #gpointer, #gint*,
|
|
and #gchar* respectively.
|
|
|
|
g_direct_hash() is also the appropriate hash function for keys
|
|
of the form `GINT_TO_POINTER (n)` (or similar macros).
|
|
|
|
A good hash functions should produce
|
|
hash values that are evenly distributed over a fairly large range.
|
|
The modulus is taken with the hash table size (a prime number) to
|
|
find the '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>

this works for plain files, pipes, and sockets.
|
|
|
|
The returned #GIOChannel has a reference count of 1.
|
|
|
|
The default encoding for #GIOChannel is UTF-8. If your application
|
|
is reading output from a command using via pipe, you may need to set
|
|
the encoding to the encoding of the current locale (see
|
|
g_get_charset()) with the g_io_channel_set_encoding() function.
|
|
By default, the fd passed will not be closed when the final reference
|
|
to the #GIOChannel data structure is dropped.
|
|
|
|
If you want to read raw binary data without interpretation, then
|
|
call the g_io_channel_set_encoding() function with %NULL for the
|
|
encoding argument.
|
|
|
|
This function is available in GLib on Windows, too, but you should
|
|
avoid using it on Windows. The domain of file descriptors and
|
|
sockets overlap. There is no way for GLib to know which one you mean
|
|
in case the argument you pass to this function happens to be both a
|
|
valid file descriptor and socket. If that happens a warning is
|
|
issued, and GLib assumes that it is the file descriptor you mean.</doc>

A buffered channel can only be set unbuffered if the channel's
|
|
internal buffers have been flushed. Newly created channels or
|
|
channels which have returned %G_IO_STATUS_EOF
|
|
not require such a flush. For write-only channels, a call to

g_io_channel_flush () is sufficient. For all other channels,

the buffers may be flushed by a call to g_io_channel_seek_position ().
|

This includes the possibility of seeking with seek type %G_SEEK_CUR
|
|
and an offset of zero. Note that this means that socket-based
|
|
channels cannot be set unbuffered once they have had data
|
|
read from them.
|

On unbuffered channels, it is safe to mix read and write

calls from the new and old APIs, if this is necessary for

|
|
The internal encoding is always UTF-8. The default encoding
|
|
for the external file is UTF-8.
|
|
|
|
The encoding %NULL is safe to use with binary data.
|
|
|
|
The encoding can only be set if one of the following conditions
|
|
is true:
|
|
|
|
- The channel was just created, and has not been written to or read from yet.
|
|
|
|
- The channel is write-only.
|
|
|
|
- The channel is a file, and the file pointer was just repositioned
|
|
by a call to g_io_channel_seek_position(). (This flushes all the
|
|
internal buffers.)
|
|
|
|
- The current encoding is %NULL or UTF-8.
|
|
|
|
- One of the (new API) read functions has just returned %G_IO_STATUS_EOF
|
|
(or, in the case of g_io_channel_read_to_end(), %G_IO_STATUS_NORMAL).
|
|
|
|
- One of the functions g_io_channel_read_chars() or
|
|
g_io_channel_read_unichar() has returned %G_IO_STATUS_AGAIN or
|
|
%G_IO_STATUS_ERROR. This may be useful in the case of
|
|
%G_CONVERT_ERROR_ILLEGAL_SEQUENCE.
|
|
Returning one of these statuses from g_io_channel_read_line(),
|
|
g_io_channel_read_line_string(), or g_io_channel_read_to_end()
|
|
does not guarantee that the encoding can be changed.
|
|
|
|
Channels which do not meet one of the above conditions cannot call

g_io_channel_seek_position() with an offset of %G_SEEK_CUR, and, if

#G_LOCK_DEFINE defines a lock. It can appear in any place where

mangled to get the name of the #GMutex. This means that you

|
|
|
|
Libraries should define this so that any messages
|
|
which they log can be differentiated from messages from other
|
|
libraries and application code. But be careful not to define
|
|
it in any public header files.
|
|
|
|
Log domains must be unique, and it is recommended that they are the
|
|
application or library name, optionally followed by a hyphen and a sub-domain
|
|
name. For example, `bloatpad` or `bloatpad-io`.
|
|
|
|
If undefined, it defaults to the default %NULL (or `""`) log domain; this is
|
|
not advisable, as it cannot be filtered against using the `G_MESSAGES_DEBUG`
|
|
environment variable.
|
|
|
|
For example, GTK+ uses this in its `Makefile.am`:
|
|
|[
|
|
AM_CPPFLAGS = -DG_LOG_DOMAIN=\"Gtk\"
|
|
]|
|
|
|
|
Applications can choose to leave it as the default %NULL (or `""`)
|
|
domain. However, defining the domain offers the same advantages as
|
|
above.</doc>

|
|
|
|
In contrast with g_list_copy(), this function uses @func to make
|
|
a copy of each list element, in addition to copying the list
|
|
container itself.
|
|
|
|
@func, as a #GCopyFunc, takes two arguments, the data to be copied
|
|
and a @user_data pointer. On common processor architectures, it's safe to
|
|
pass %NULL as @user_data if the copy function takes only one argument. You
|
|
may get compiler warnings from this though if compiling with GCC’s
|
|
`-Wcast-function-type` warning.
|
|
|
|
For instance, if @list holds a list of GObjects, you can do:
|
|
|[<!-- language="C" -->
|
|
another_list = g_list_copy_deep (list, (GCopyFunc) g_object_ref, NULL);
|
|
]|
|
|

|
|
|[<!-- language="C" -->

g_list_free_full (another_list, g_object_unref);

specification](https://www.freedesktop.org/software/systemd/man/systemd.journal-fields.html).
|
|
See g_log_structured() for more information.
|
|
|
|
Writer functions must ignore fields which they do not recognise, unless they
|
|
can write arbitrary binary output, as field values may be arbitrary binary.
|
|
|
|
@log_level is guaranteed to be included in @fields as the `PRIORITY` field,
|
|
but is provided separately for convenience of deciding whether or where to
|
|
output the log entry.
|
|
|
|
Writer functions should return %G_LOG_WRITER_HANDLED if they handled the log
|
|
message successfully or if they deliberately ignored it. If there was an
|
|
error handling the message (for example, if the writer function is meant to
|
|
send messages to a remote logging server and there is a network error), it
|
|
should return %G_LOG_WRITER_UNHANDLED. This allows writer functions to be

If @context is %NULL then the global default main context — as

returned by g_main_context_default() — is used.
|
|
|
|
If @context is owned by the current thread, @function is called

directly. Otherwise, if @context is the thread-default main context

of the current thread and g_main_context_acquire() succeeds, then
|

@function is called and g_main_context_release() is called

afterwards.

|
|
In any other case, an idle source is created to call @function and

|
that source is attached to @context (presumably to be run in another

thread). The idle source is attached with #G_PRIORITY_DEFAULT

priority. If you want a different priority, use

g_main_context_invoke_full().

<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>

|
|
|
|
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.
|
|
|
|
|[<!-- language="C" -->
|
|
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->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 =
|

|

|
|
NULL,
|
|
NULL,
|
|
counter_error
|
|
};
|
|
]|
|
|
|
|
In order to allow this parser to be easily used as a subparser, the
|
|
following interface is provided:
|
|
|
|
|[<!-- language="C" -->
|
|
void
|
|
start_counting (GMarkupParseContext *context)
|
|
{
|
|
CounterData *data = g_slice_new (CounterData);
|
|
|
|
data->tag_count = 0;
|
|
g_markup_parse_context_push (context, &counter_subparser, data);
|
|
}
|
|
|
|
gint
|
|
end_counting (GMarkupParseContext *context)
|
|
{
|
|
CounterData *data = g_markup_parse_context_pop (context);
|
|
int result;
|
|
|
|
result = data->tag_count;
|
|
g_slice_free (CounterData, data);
|
|
|
|
return result;
|
|
}
|
|
]|
|
|
|
|
The subparser would then be used as follows:
|
|
|

|[<!-- language="C" -->
|
|
static void start_element (context, element_name, ...)
|
|
{

|
|
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:
|
|
|[<!-- language="C" -->
|
|
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:
|
|
|[<!-- language="C" -->
|
|
int
|
|
give_me_next_number (void)
|
|
{
|
|
static GMutex mutex;
|
|
static int current_number = 0;
|
|
int ret_val;
|
|
|
|
g_mutex_lock (&mutex);
|
|
ret_val = current_number = calc_next_number (current_number);
|
|
g_mutex_unlock (&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>

This function is similar to g_option_context_parse() except that it
|

respects the normal memory rules when dealing with a strv instead of

|
assuming that the passed-in array is the argv of the main function.
|

In particular, strings that are removed from the arguments list will
|

be freed using g_free().

On Windows, the strings are expected to be in UTF-8. This is in
|
|
contrast to g_option_context_parse() which expects them to be in the

|
system codepage, which is how they are passed as @argv to main().
|

See g_win32_get_command_line() for a solution.

<doc xml:space="preserve">Sets strict POSIX mode.
|

By default, this mode is disabled.
|
|
|
|
In strict POSIX mode, the first non-argument parameter encountered
|
|
(eg: filename) terminates argument processing. Remaining arguments
|
|
are treated as non-options and are not attempted to be parsed.
|
|
|
|
If strict POSIX mode is disabled then parsing is done in the GNU way
|
|
where option arguments can be freely mixed with non-options.
|
|
|
|
As an example, consider "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>

The @parameter_string can serve multiple purposes. It can be used

to add descriptions for "rest" arguments, which are not parsed by

the #GOptionContext, typically something like "FILES" or

"FILE1 FILE2...". If you are using #G_OPTION_REMAINING for

<doc xml:space="preserve">A macro to assist with the static initialisation of a #GPrivate.
|
|
|
|
This macro is useful for the case that a #GDestroyNotify function

should be associated with the key. This is needed when the key will be
|
|
used to point at memory that should be deallocated when the thread
|
|
exits.
|
|
|
|
Additionally, the #GDestroyNotify will also be called on the previous
|
|
value stored in the key when g_private_replace() is used.
|
|
|
|
If no #GDestroyNotify is needed, then use of this macro is not
|
|
required -- if the #GPrivate is declared in static scope then it will
|
|
be properly initialised by default (ie: to all zeros). See the

pthread_setspecific()/pthread_getspecific() APIs on POSIX and to

TlsSetValue()/TlsGetValue() on Windows.
|

If you don't already know why you might want this functionality,

then you probably don't need it.
|

|
|
#GPrivate is a very limited resource (as far as 128 per program,
|
|
shared between all libraries). It is also not possible to destroy a
|
|
#GPrivate after it has been used. As such, it is only ever acceptable
|
|
to use #GPrivate in static scope, and even then sparingly so.
|
|
|
|
See G_PRIVATE_INIT() for a couple of examples.
|
|
|
|
The #GPrivate structure should be considered opaque. It should only
|
|
be accessed via the g_private_ functions.</doc>

<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()).
|
|
|
|
It is unspecified whether readers or writers have priority in acquiring the
|
|
lock when a reader already holds the lock and a writer is queued to acquire
|
|
it.
|
|
|
|
Here is an example for an array with access functions:
|
|
|[<!-- language="C" -->
|
|
GRWLock lock;
|
|
GPtrArray *array;
|
|
|
|
gpointer
|
|
my_array_get (guint index)
|
|
{
|
|
gpointer retval = NULL;
|
|
|
|
if (!array)
|
|
return NULL;
|
|
|
|
g_rw_lock_reader_lock (&lock);
|
|
if (index < array->len)
|
|
retval = g_ptr_array_index (array, index);
|
|
g_rw_lock_reader_unlock (&lock);
|
|
|
|
return retval;
|
|
}
|
|
|
|
void
|
|
my_array_set (guint index, gpointer data)
|
|
{
|
|
g_rw_lock_writer_lock (&lock);
|
|
|
|
if (!array)
|
|
array = g_ptr_array_new ();
|
|
|
|
if (index >= array->len)
|
|
g_ptr_array_set_size (array, index+1);
|
|
g_ptr_array_index (array, index) = data;
|
|
|
|
g_rw_lock_writer_unlock (&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>

|
|
<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 longest match in the @string is retrieved, it is not possible

"<a> <b> <c>" against the pattern "<.*>"
|
|
you get "<a> <b> <c>".
|
|
|
|
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
|
|
"<a> <b> <c>" against the pattern "<.*>;"
|
|
you would obtain three matches: "<a> <b> <c>",
|
|
"<a> <b>" and "<a>".
|
|
|
|
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.

In contrast with g_slist_copy(), this function uses @func to make a copy of
|
|
each list element, in addition to copying the list container itself.
|
|
|
|
@func, as a #GCopyFunc, takes two arguments, the data to be copied
|
|
and a @user_data pointer. On common processor architectures, it's safe to
|
|
pass %NULL as @user_data if the copy function takes only one argument. You
|
|
may get compiler warnings from this though if compiling with GCC’s
|
|
`-Wcast-function-type` warning.
|
|
|
|
For instance, if @list holds a list of GObjects, you can do:
|
|
|[<!-- language="C" -->
|
|
another_list = g_slist_copy_deep (list, (GCopyFunc) g_object_ref, NULL);

]|

@free_func must not modify the list (eg, by removing the freed

element from it).

It can be combined with g_steal_pointer() to ensure the list head pointer

is cleared before any of the list elements are freed, to prevent double frees

For idle sources, the prepare and check functions always return %TRUE

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>

<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>

g_set_user_dirs() to set XDG directories to point into subdirectories of it

test finishes successfully. Note that this doesn’t take effect until

g_test_run() is called, so calls to (for example) g_get_user_home_dir() will

return the system-wide value when made in a test program’s main() function.
|

The following functions will return subdirectories of the temporary directory

when this option is used. The specific subdirectory paths in use are not

guaranteed to be stable API — always use a getter function to retrieve them.

Note: as a general rule of automake, files that are generated only as

part of the build-from-git process (but then are distributed with the

<doc xml:space="preserve">The #GThread struct represents a running thread. This struct

is returned by g_thread_new() or g_thread_try_new(). You can

obtain the #GThread struct representing the current thread by

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

explicitly.

<doc xml:space="preserve">This function creates a new thread. The new thread starts by invoking
|
|
@func with the argument data. The thread will run until @func returns
|
|
or until g_thread_exit() is called from the new thread. The return value
|
|
of @func becomes the return value of the thread, which can be obtained
|
|
with g_thread_join().
|
|
|
|
The @name can be useful for discriminating threads in a debugger.
|
|
It is not used for other purposes and does not have to be unique.
|
|
Some systems restrict the length of @name to 16 bytes.
|
|
|
|
If the thread can not be created the program aborts. See
|
|
g_thread_try_new() if you want to attempt to deal with failures.
|
|
|
|
If you are using threads to offload (potentially many) short-lived tasks,
|
|
#GThreadPool may be more appropriate than manually spawning and tracking
|
|
multiple #GThreads.
|
|
|
|
To free the struct returned by this function, use g_thread_unref().
|
|
Note that g_thread_join() implicitly unrefs the #GThread as well.
|
|
|
|
New threads by default inherit their scheduler policy (POSIX) or thread
|
|
priority (Windows) of the thread creating the new thread.
|
|
|
|
This behaviour changed in GLib 2.64: before threads on Windows were not
|
|
inheriting the thread priority but were spawned with the default priority.
|
|
Starting with GLib 2.64 the behaviour is now consistent between Windows and
|
|
POSIX and all threads inherit their parent thread's priority.</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.

|
|
ISO 8601 allows a large number of date/time formats, with or without

punctuation and optional elements. The format returned by this function

is a complete date and time, with optional punctuation included, the

@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, an absolute path to a file
|
|
somewhere else, or a 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 <= d <= 6) of week w (1 <= w <= 5) of month m (1 <= m <= 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.

This function is similar to g_time_zone_find_interval(), with the
|
|
difference that it always succeeds (by making the adjustments
|
|
described below).
|
|
|
|
In any of the cases where g_time_zone_find_interval() succeeds then
|
|
this function returns the same value, without modifying @time_.
|
|
|
|
This function may, however, modify @time_ in order to deal with
|
|
non-existent times. If the non-existent local @time_ of 02:30 were
|
|
requested on March 14th 2010 in Toronto then this function would
|
|
adjust @time_ to be 03:00 and return the interval containing the

adjusted time.</doc>

<doc xml:space="preserve">Finds an interval within @tz that corresponds to the given @time_.
|
|
The meaning of @time_ depends on @type.
|
|
|
|
If @type is %G_TIME_TYPE_UNIVERSAL then this function will always
|
|
succeed (since universal time is monotonic and continuous).
|
|
|
|
Otherwise @time_ is treated as local time. The distinction between
|
|
%G_TIME_TYPE_STANDARD and %G_TIME_TYPE_DAYLIGHT is ignored except in
|
|
the case that the given @time_ is ambiguous. In Toronto, for example,
|
|
01:30 on November 7th 2010 occurred twice (once inside of daylight
|
|
savings time and the next, an hour later, outside of daylight savings
|
|
time). In this case, the different value of @type would result in a
|
|
different interval being returned.
|
|
|
|
It is still possible for this function to fail. In Toronto, for
|
|
example, 02:00 on March 14th 2010 does not exist (due to the leap
|
|
forward to begin daylight savings time). -1 is returned in that
|
|
case.</doc>

<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:
|
|
|
|
|[<!-- language="C" -->
|
|
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 look up the cached items and stores a pointer to this
|
|
hash table in static storage. The hash table is freed when there
|
|
are zero items in the type cache.
|
|
|
|
Although these sizes may seem large it is important to remember
|
|
that a program will probably only have a very small number of
|
|
different types of values in it and that only one type information
|
|
structure is required for many different values of the same type.
|
|
|
|
## Buffer Management Memory
|
|
|
|
#GVariant uses an internal buffer management structure to deal
|
|
with the various different possible sources of 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 bytes 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>

Think of this function as an analogue to g_strdup_printf().
|
|
|
|
The type of the created instance and the arguments that are expected

|
by this function are determined by @format_string. See the section on

the syntax of the format string is very likely to be extended in the

future.

The first character of the format string must not be '*' '?' '@' or

Note that the arguments must be of the correct width for their types

|
|
|
|
@type is the type of #GVariant instance that will be constructed.
|
|
The interpretation of @data depends on knowing the type.
|
|
|
|
@data is not modified by this function and must remain valid with an
|
|
unchanging value until such a time as @notify is called with
|
|
@user_data. If the contents of @data change before that time then
|
|
the result is undefined.
|
|
|
|
If @data is trusted to be serialised data in normal form then
|
|
@trusted should be %TRUE. This applies to serialised data created
|
|
within this process or read from a trusted location on the disk (such
|
|
as a file installed in /usr/lib alongside your application). You
|
|
should set trusted to %FALSE if @data is read from the network, a
|
|
file in the user's home directory, etc.
|
|
|
|
If @data was not stored in this machine's native endianness, any multi-byte
|
|
numeric values in the returned variant will also be in non-native
|
|
endianness. g_variant_byteswap() can be used to recover the original values.
|
|
|
|
@notify will be called with @user_data when @data is no longer
|
|
needed. The exact time of this call is unspecified and might even be
|
|
before this function returns.
|
|
|
|
Note: @data must be backed by memory that is aligned appropriately for the
|
|
@type being loaded. Otherwise this function will internally create a copy of
|

the memory (since GLib 2.60) or (in older versions) fail and exit the

@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

Note that the arguments must be of the correct width for their types

the [GVariant varargs documentation][gvariant-varargs].
|
|

Consider this simple example:

|[<!-- language="C" -->
|
|
g_variant_new_parsed ("[('one', 1), ('two', %i), (%s, 3)]", 2, "three");
|
|

|

In the example, the variable argument parameters are collected and

[('one', 1), ('two', 2), ('three', 3)]

This function is intended only to be used with @format as a string

The return value will be floating if it was a newly created GVariant

In order to behave correctly in all cases it is necessary for the

|

<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
|
|
calling function to g_variant_ref_sink() the return result before
|
|
returning control to the user that originally provided the pointer.
|
|
At this point, the caller will have their own full reference to the
|
|
result. This can also be done by adding the result to a container,
|
|
or by passing it to another g_variant_new() call.</doc>

Comparison is only defined for basic types (ie: booleans, numbers,

strings). For booleans, %FALSE is less than %TRUE. Numbers are

ordered in the usual way. Strings are in ASCII lexographical order.

It is a programmer error to attempt to compare container values or

two values that have types that are not exactly equal. For example,

you cannot compare a 32-bit signed integer with a 32-bit unsigned

integer. Also note that this function is not particularly

valid for as long as @value exists.

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

In the case that @value is already in serialised form, this function

it. As a result, file formats or network messages that incorporate

serialised #GVariants must include this information either

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

This function works with dictionaries of the type a{s*} (and equally
|
|
well with type a{o*}, but we only further discuss the string case
|
|
for sake of clarity).
|
|
|
|
In the event that @dictionary has the type a{sv}, the @expected_type
|
|
string specifies what type of value is expected to be inside of the
|
|
variant. If the value inside the variant has a different type then
|
|
%NULL is returned. In the event that @dictionary has a value type other
|
|
than v then @expected_type must directly match the value type and it is
|
|
used to unpack the value directly or an error occurs.
|
|
|
|
In either case, if @key is not found in @dictionary, %NULL is returned.
|
|
|
|
If the key is found and the value has the correct type, it is
|
|
returned. If @expected_type was specified then any non-%NULL return
|
|
value will have this type.

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

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>

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

|
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

In case of any error, %NULL will be returned. If @error is non-%NULL

@type must be non-%NULL. It specifies the type of container to

<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.

|
|
|
|
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():
|
|
|[<!-- language="C" -->
|
|
// Iterates a dictionary of type 'a{sv}'
|
|
void
|
|
iterate_dictionary (GVariant *dictionary)
|
|
{
|
|
GVariantIter iter;
|
|
GVariant *value;
|
|
gchar *key;
|
|
|
|
g_variant_iter_init (&iter, dictionary);
|
|
while (g_variant_iter_loop (&iter, "{sv}", &key, &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 '&' prefix to avoid allocating any memory at all (and
|
|
thereby avoiding the need to free anything as well).

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)}))". In order to not hit memory limits, #GVariant
|
|
imposes a limit on recursion depth of 65 nested containers. This is the
|
|
limit in the D-Bus specification (64) plus one to allow a #GDBusMessage to
|
|
be nested in a top-level tuple.
|
|
|
|
The meaning of each of the characters is as follows:
|
|
- `b`: the type string of %G_VARIANT_TYPE_BOOLEAN; a boolean value.
|
|
- `y`: the type string of %G_VARIANT_TYPE_BYTE; a byte.
|
|
- `n`: the type string of %G_VARIANT_TYPE_INT16; a signed 16 bit integer.
|
|
- `q`: the type string of %G_VARIANT_TYPE_UINT16; an unsigned 16 bit integer.
|
|
- `i`: the type string of %G_VARIANT_TYPE_INT32; a signed 32 bit integer.
|
|
- `u`: the type string of %G_VARIANT_TYPE_UINT32; an unsigned 32 bit integer.
|
|
- `x`: the type string of %G_VARIANT_TYPE_INT64; a signed 64 bit integer.
|
|
- `t`: the type string of %G_VARIANT_TYPE_UINT64; an unsigned 64 bit integer.
|
|
- `h`: the type string of %G_VARIANT_TYPE_HANDLE; a signed 32 bit value
|
|
that, by convention, is used as an index into an array of file
|
|
descriptors that are sent alongside a D-Bus message.
|
|
- `d`: the type string of %G_VARIANT_TYPE_DOUBLE; a double precision
|
|
floating point value.
|
|
- `s`: the type string of %G_VARIANT_TYPE_STRING; a string.
|
|
- `o`: the type string of %G_VARIANT_TYPE_OBJECT_PATH; a string in the form
|
|
of a D-Bus object path.
|
|
- `g`: the type string of %G_VARIANT_TYPE_SIGNATURE; a string in the form of
|
|
a D-Bus type signature.
|
|
- `?`: the type string of %G_VARIANT_TYPE_BASIC; an indefinite type that
|
|
is a supertype of any of the basic types.
|
|
- `v`: the type string of %G_VARIANT_TYPE_VARIANT; a container type that
|
|
contain any other type of value.
|
|
- `a`: used as a prefix on another type string to mean an array of that
|
|
type; the type string "ai", for example, is the type of an array of
|
|
signed 32-bit integers.
|
|
- `m`: used as a prefix on another type string to mean a "maybe", or
|
|
"nullable", version of that type; the type string "ms", for example,
|
|
is the type of a value that maybe contains a string, or maybe contains
|
|
nothing.
|
|
- `()`: used to enclose zero or more other concatenated type strings to
|
|
create a tuple type; the type string "(is)", for example, is the type of
|
|
a pair of an integer and a string.
|
|
- `r`: the type string of %G_VARIANT_TYPE_TUPLE; an indefinite type that is
|
|
a supertype of any tuple type, regardless of the number of items.
|
|
- `{}`: used to enclose a basic type string concatenated with another type
|
|
string to create a dictionary entry type, which usually appears inside of
|
|
an array to form a dictionary; the type string "a{sd}", for example, is
|
|
the type of a dictionary that maps strings to double precision floating
|
|
point values.
|

|
The first type (the basic type) is the key type and the second type is
|
|
the value type. The reason that the first type is restricted to being a
|
|
basic type is so that it can easily be hashed.
|
|
- `*`: the type string of %G_VARIANT_TYPE_ANY; the indefinite type that is
|
|
a supertype of all types. Note that, as with all type strings, this
|
|
character represents exactly one type. It cannot be used inside of tuples
|
|
to mean "any number of items".
|
|
|
|
Any type string of a container that contains an indefinite type is,
|
|
itself, an indefinite type. For example, the type string "a*"
|
|
(corresponding to %G_VARIANT_TYPE_ARRAY) is an indefinite type
|
|
that is a supertype of every array type. "(*s)" is a supertype
|
|
of all tuples that contain exactly two items where the second
|
|
item is a string.
|
|
|
|
"a{?*}" is an indefinite type that is a supertype of all arrays
|
|
containing dictionary entries where the key is any basic type and
|
|
the value is any type at all. This is, by definition, a dictionary,
|
|
so this type string corresponds to %G_VARIANT_TYPE_DICTIONARY. Note
|
|
that, due to the restriction that the key of a dictionary entry must
|
|
be a basic type, "{**}" is not a valid type string.</doc>

<doc xml:space="preserve">Allocates @size bytes on the stack; these bytes will be freed when the current

stack frame is cleaned up. This macro essentially just wraps the alloca()
|
|
function present on most UNIX variants.
|
|
Thus it provides the same advantages and pitfalls as alloca():
|
|
|
|
- alloca() is very fast, as on most systems it's implemented by just adjusting
|
|
the stack pointer register.
|
|
|
|
- It doesn't cause any memory fragmentation, within its scope, separate alloca()
|
|
blocks just build up and are released together at function end.
|
|
|
|
- Allocation sizes have to fit into the current stack frame. For instance in a
|
|
threaded environment on Linux, the per-thread stack size is limited to 2 Megabytes,
|
|
so be sparse with alloca() uses.
|
|
|
|
- Allocation failure due to insufficient stack space is not indicated with a %NULL
|
|
return like e.g. with malloc(). Instead, most systems probably handle it the same
|
|
way as out of stack space situations from infinite function recursion, i.e.
|
|
with a segmentation fault.
|
|
|
|
- Special care has to be taken when mixing alloca() with GNU C variable sized arrays.
|
|
Stack space allocated with alloca() in the same scope as a variable sized array
|
|
will be freed together with the variable sized array upon exit of that scope, and

not upon exit of the enclosing function scope.</doc>

This function behaves like the standard strtod() function

|

A limitation of the implementation is that this function

This function is typically used when reading configuration

To handle input from the user you should normally use the

locale-sensitive system strtod() function.

To convert from a #gdouble to a string in a locale-insensitive

way, use g_ascii_dtostr().

|
|
<doc xml:space="preserve">Converts a string to a #guint64 value.
|
|
This function behaves like the standard strtoull() function
|
|
does in the C locale. It does this without actually
|
|
changing the current locale, since that would not be
|
|
thread-safe.
|
|
|
|
Note that input with a leading minus sign (`-`) is accepted, and will return
|
|
the negation of the parsed number, unless that would overflow a #guint64.
|
|
Critically, this means you cannot assume that a short fixed length input will
|
|
never result in a low return value, as the input could have a leading `-`.
|
|
|
|
This function is typically used when reading configuration
|
|
files or other non-user input that should be locale independent.
|
|
To handle input from the user you should normally use the
|
|
locale-sensitive system strtoull() function.
|
|
|
|
If the correct value would cause overflow, %G_MAXUINT64
|
|
is returned, and `ERANGE` is stored in `errno`.
|
|
If the base is outside the valid range, zero is returned, and
|
|
`EINVAL` is stored in `errno`.
|
|
If the string conversion fails, zero is returned, and @endptr returns
|
|
@nptr (if @endptr is non-%NULL).</doc>

If the assertion fails (i.e. the expression is not true),
|
|
an error message is logged and the application is either
|
|
terminated or the testcase marked as failed.
|
|
|
|
Note that unlike g_assert(), this macro is unaffected by whether
|
|
`G_DISABLE_ASSERT` is defined. Hence it should only be used in tests and,
|
|
conversely, g_assert() should not be used in tests.

|
|
<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>

representation. By calling this function multiple times you can convert
|

data in chunks to avoid having to have the full encoded data in memory.
|
|
|
|
When all of the data has been converted you must call
|
|
g_base64_encode_close() to flush the saved state.
|
|
|
|
The output buffer must be large enough to fit all the data that will
|
|
be written to it. Due to the way base64 encodes you will need
|
|
at least: (@len / 3 + 1) * 4 + 4 bytes (+ 4 may be needed in case of

|
non-zero state). If you enable line-breaking you will need at least:
|
|
((@len / 3 + 1) * 4 + 4) / 76 + 1 bytes of extra space.
|
|
|
|
@break_lines is typically used when putting base64-encoded data in emails.
|
|
It breaks the lines at 76 columns instead of putting all of the text on
|
|
the same line. This avoids problems with long lines in the email system.
|
|
Note however that it breaks the lines with `LF` characters, not
|
|
`CR LF` sequences, so the result cannot be passed directly to SMTP

or certain other protocols.</doc>

On POSIX platforms, the following restrictions apply to this API
|
|
due to limitations in POSIX process interfaces:
|
|
|
|
* @pid must be a child of this process
|
|
* @pid must be positive
|
|
* the application must not call `waitpid` with a non-positive
|
|
first argument, for instance in another thread
|
|
* the application must not wait for @pid to exit by any other
|
|
mechanism, including `waitpid(pid, ...)` or a second child-watch
|
|
source for the same @pid
|
|
* the application must not ignore SIGCHILD
|
|
|
|
If any of those conditions are not met, this and related APIs will
|
|
not work correctly. This can often be diagnosed via a GLib warning
|
|
stating that `ECHILD` was received by `waitpid`.
|
|
|
|
Calling `waitpid` for specific processes other than @pid remains a
|
|
valid thing to do.</doc>

Despite the fact that @bytes_read can return information about partial
|
|
characters, the g_convert_... functions are not generally suitable
|
|
for streaming. If the underlying converter maintains internal state,
|
|
then this won't be preserved across successive calls to g_convert(),
|
|
g_convert_with_iconv() or g_convert_with_fallback(). (An example of
|
|
this is the GNU C converter for CP1255 which does not emit a base
|
|
character until it knows that the next character is not a mark that
|
|
could combine with the base character.)
|
|
|
|
Characters which are valid in the input character set, but which have no
|
|
representation in the output character set will result in a
|
|
%G_CONVERT_ERROR_ILLEGAL_SEQUENCE error. This is in contrast to the iconv()
|
|
specification, which leaves this behaviour implementation defined. Note that
|
|
this is the same error code as is returned for an invalid byte sequence in
|
|
the input character set. To get defined behaviour for conversion of
|
|
unrepresentable characters, use g_convert_with_fallback().</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
|
|
file which is then renamed to the final name. Notes:
|
|
|
|
- On UNIX, if @filename already exists hard links to @filename will break.
|
|
Also since the file is recreated, existing permissions, access control
|
|
lists, metadata etc. may be lost. If @filename is a symbolic link,
|
|
the link itself will be replaced, not the linked file.
|
|
|
|
- On UNIX, if @filename already exists and is non-empty, and if the system
|
|
supports it (via a journalling filesystem or equivalent), the fsync()
|
|
call (or equivalent) will be used to ensure atomic replacement: @filename
|
|
will contain either its old contents or @contents, even in the face of
|
|
system power loss, the disk being unsafely removed, etc.
|
|
|
|
- On UNIX, if @filename does not already exist or is empty, there is a
|
|
possibility that system power loss etc. after calling this function will
|
|
leave @filename empty or full of NUL bytes, depending on the underlying
|
|
filesystem.
|
|
|
|
- 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!

}

|

|
|
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

subsequent character sets are used when trying to generate a displayable

|
|
|
|
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

|

is also put in the list of encodings.

The returned @charsets belong to GLib and must not be freed.

Note that on Unix, regardless of the locale character set or

As with most UNIX tools, this function will return the value of the

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).
|
|

old behaviour (and if you don't wish to increase your GLib

This is used if no log handler has been set for the particular log

domain and log level combination. It outputs the message to stderr

|
messages should be prefixed by the program name and PID of the

aplication.

- `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.

This example adds a log handler for all critical messages from GTK+:

g_log_set_handler ("GLib", G_LOG_LEVEL_MASK | G_LOG_FLAG_FATAL

be aborted by calling G_BREAKPOINT() at the end of this function. If the log writer returns
|
|
%G_LOG_WRITER_UNHANDLED (failure), no other fallback writers will be tried.
|
|
See the documentation for #GLogWriterFunc for information on chaining
|
|
writers.
|
|
|
|
The structured data is provided as key–value pairs, where keys are UTF-8
|
|
strings, and values are arbitrary pointers — typically pointing to UTF-8
|
|
strings, but that is not a requirement. To pass binary (non-nul-terminated)
|
|
structured data, use 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:
|
|
|[<!-- language="C" -->
|
|
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:
|
|
|[<!-- language="C" -->
|
|
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>

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()
|
|
|
|
|[<!-- language="C" -->
|
|
gpointer
|
|
allocate_memory (gsize size)
|
|
{
|
|
FreeListBlock *block = g_new (FreeListBlock, 1);
|
|
block->mem = g_malloc (size);
|
|
block->depth = g_main_depth ();
|
|
free_list = g_list_prepend (free_list, block);
|
|
return block->mem;
|
|
}
|
|
|
|
void
|
|
free_allocated_memory (void)
|
|
{
|
|
GList *l;
|
|
|
|
int depth = g_main_depth ();
|
|
for (l = free_list; l; );
|
|
{
|
|
GList *next = l->next;
|
|
FreeListBlock *block = l->data;
|
|
if (block->depth > depth)
|
|
{
|
|
g_free (block->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>

#GMarkupParser start_element function, dealing with common error
|
|
conditions and supporting boolean values.
|
|
|
|
This utility function is not required to write a parser but can save
|
|
a lot of typing.
|
|
|
|
The @element_name, @attribute_names, @attribute_values and @error
|
|
parameters passed to the start_element callback should be passed
|
|
unmodified to this function.
|
|
|
|
Following these arguments is a list of "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

%G_MARKUP_ERROR_INVALID_CONTENT). In all of these cases %FALSE

will be returned and @error will be set as appropriate.</doc>

Note that this is a somewhat vague concept on Windows.
|
|
|
|
On POSIX systems, an absolute file name is well-defined. It always
|
|
starts from the single root directory. For example "/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
|
|

If the pattern does not match anywhere in the string, then the

This function is equivalent to g_regex_split() but it does

|
|
|
|
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
|
|
an 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>

|
<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 or 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
|
|
(g_child_watch_add()) to be notified about the death of the child process,
|
|
otherwise it will stay around as a zombie process until this process exits.
|
|
Eventually you must call g_spawn_close_pid() on the @child_pid, in order to
|
|
free resources which may be associated with the child process. (On Unix,
|
|
using a child watch is equivalent to calling waitpid() or handling
|
|
the %SIGCHLD signal manually. On Windows, calling g_spawn_close_pid()
|
|
is equivalent to calling CloseHandle() on the process handle returned
|
|
in @child_pid). See g_child_watch_add().
|
|
|
|
Open UNIX file descriptors marked as `FD_CLOEXEC` will be automatically
|
|
closed in the child process. %G_SPAWN_LEAVE_DESCRIPTORS_OPEN means that
|
|
other open file descriptors will be inherited by the child; otherwise all
|
|
descriptors except stdin/stdout/stderr will be closed before calling exec()
|
|
in the child. %G_SPAWN_SEARCH_PATH means that @argv[0] need not be an
|
|
absolute path, it will be looked for in the `PATH` environment
|
|
variable. %G_SPAWN_SEARCH_PATH_FROM_ENVP means need not be an
|
|
absolute path, it will be looked for in the `PATH` variable from
|
|
@envp. If both %G_SPAWN_SEARCH_PATH and %G_SPAWN_SEARCH_PATH_FROM_ENVP
|
|
are used, the value from @envp takes precedence over the environment.
|
|
%G_SPAWN_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().
|
|
|
|
On modern UNIX platforms, GLib can use an efficient process launching
|
|
codepath driven internally by posix_spawn(). This has the advantage of
|
|
avoiding the fork-time performance costs of cloning the parent process
|
|
address space, and avoiding associated memory overcommit checks that are
|
|
not relevant in the context of immediately executing a distinct process.
|
|
This optimized codepath will be used provided that the following conditions
|
|
are met:
|
|
|
|
1. %G_SPAWN_DO_NOT_REAP_CHILD is set
|
|
2. %G_SPAWN_LEAVE_DESCRIPTORS_OPEN is set
|
|
3. %G_SPAWN_SEARCH_PATH_FROM_ENVP is not set
|
|
4. @working_directory is %NULL
|
|
5. @child_setup is %NULL
|
|
6. The program is of a recognised binary format, or has a shebang. Otherwise, GLib will have to execute the program through the shell, which is not done using the optimized codepath.
|
|
|
|
If you are writing a GTK+ application, and the program you are spawning is a
|
|
graphical application too, then to ensure that the spawned program opens its
|
|
windows on the right screen, you may want to use #GdkAppLaunchContext,
|
|
#GAppLaunchContext, or set the %DISPLAY environment variable.</doc>

|
|
<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>

Conceptually, this transfers the ownership of the pointer from the

reference).

|
|

This can be very useful when combined with g_autoptr() to prevent the
|
|
return value of a function from being automatically freed. Consider
|
|
the following example (which only works on GCC and clang):
|
|
|
|
|[
|
|
GObject *
|
|
create_object (void)
|
|
{
|
|
g_autoptr(GObject) obj = g_object_new (G_TYPE_OBJECT, NULL);
|
|
|
|
if (early_error_case)
|
|
return NULL;
|
|
|
|
return g_steal_pointer (&obj);
|
|
}
|
|
]|
|
|
|
|
It can also be used in similar ways for 'out' parameters and is
|
|
particularly useful for dealing with optional out parameters:
|
|
|
|
|[
|
|
gboolean
|
|
get_object (GObject **obj_out)
|
|
{
|
|
g_autoptr(GObject) obj = g_object_new (G_TYPE_OBJECT, NULL);
|
|
|
|
if (early_error_case)
|
|
return FALSE;
|
|
|
|
if (obj_out)
|
|
*obj_out = g_steal_pointer (&obj);
|
|
|
|
return TRUE;
|
|
}
|
|
]|
|
|
|
|
In the above example, the object will be automatically freed in the
|
|
early error case and also in the case that %NULL was given for
|
|
@obj_out.</doc>

bit unsigned hash value starts at 5381 and for each byte 'c' in

This function calls g_str_tokenize_and_fold() on both

|
@search_term and @potential_hit. ASCII alternates are never taken
|
|
for @search_term but will be taken for @potential_hit according to

the value of @accept_alternates.
|
|
|
|
A hit occurs when each folded token in @search_term is a prefix of a

|
folded token from @potential_hit.
|
|
|
|
Depending on how you're performing the search, it will typically be
|
|
faster to call g_str_tokenize_and_fold() on each string in
|
|
your corpus and build an index on the returned folded tokens, then
|
|
call g_str_tokenize_and_fold() on the search term and
|
|
perform lookups into that index.
|
|
|
|
As some examples, searching for ‘fred’ would match the potential hit
|
|
‘Smith, Fred’ and also ‘Frédéric’. Searching for ‘Fréd’ would match
|
|
‘Frédéric’ but not ‘Frederic’ (due to the one-directional nature of
|
|
accent matching). Searching ‘fo’ would match ‘Foo’ and ‘Bar Foo

Baz’, but not ‘SFO’ (because no word has ‘fo’ as a prefix).</doc>

strncasecmp() function on platforms which support it. It is similar

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,

This function is conceptually similar to g_build_filename() except
|
|
that the first argument has been replaced with a #GTestFileType
|
|
argument.
|
|
|
|
The data file should either have been distributed with the module
|
|
containing the test (%G_TEST_DIST) or built as part of the build
|
|
system of that module (%G_TEST_BUILT).
|
|
|
|
In order for this function to work in srcdir != builddir situations,
|
|
the G_TEST_SRCDIR and G_TEST_BUILDDIR environment variables need to
|
|
have been defined. As of 2.38, this is done by the glib.mk
|
|
included in GLib. Please ensure that your copy is up to date before
|
|
using this function.
|
|
|
|
In case neither variable is set, this function will fall back to
|
|
using the dirname portion of argv[0], possibly removing ".libs".
|
|
This allows for casual running of tests directly from the commandline
|
|
in the srcdir == builddir case and should also support running of

installed tests, assuming the data files have been installed in the

|

|
This API may only be used with the old logging API (g_log() without

%G_LOG_USE_STRUCTURED defined). It will not work with the structured logging
|
|
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:
|
|
|
|
|[<!-- language="C" -->
|
|
// g_main_context_push_thread_default() should fail if the
|
|
// context is already owned by another thread.

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>

|
So far, the following arguments are understood:
|
|
|
|
- `-l`: List test cases available in a test executable.
|
|
- `--seed=SEED`: Provide a random seed to reproduce test
|
|
runs using random numbers.
|
|
- `--verbose`: Run tests verbosely.
|
|
- `-q`, `--quiet`: Run tests quietly.
|
|
- `-p PATH`: Execute all tests matching the given path.
|
|
- `-s PATH`: Skip all tests matching the given path.
|
|
This can also be used to force a test to run that would otherwise
|
|
be skipped (ie, a test whose name contains "/subprocess").
|
|
- `-m {perf|slow|thorough|quick|undefined|no-undefined}`: Execute tests according to these test modes:
|
|
|
|
`perf`: Performance tests, may take long and report results (off by default).
|
|
|
|
`slow`, `thorough`: Slow and thorough tests, may take quite long and maximize coverage
|
|
(off by default).
|
|
|
|
`quick`: Quick tests, should run really quickly and give good coverage (the default).
|
|
|
|
`undefined`: Tests for undefined behaviour, may provoke programming errors
|
|
under g_test_trap_subprocess() or g_test_expect_message() to check
|
|
that appropriate assertions or warnings are given (the default).
|
|
|
|
`no-undefined`: Avoid tests for undefined behaviour
|
|
|
|
- `--debug-log`: Debug test logging output.
|
|
|
|
Options which can be passed to @... are:
|
|
|
|
- `"no_g_set_prgname"`: Causes g_test_init() to not call g_set_prgname().
|
|
- %G_TEST_OPTION_ISOLATE_DIRS: Creates a unique temporary directory for each
|
|
unit test and uses g_set_user_dirs() to set XDG directories to point into
|
|
that temporary directory for the duration of the unit test. See the
|
|
documentation for %G_TEST_OPTION_ISOLATE_DIRS.
|
|
|
|
Since 2.58, if tests are compiled with `G_DISABLE_ASSERT` defined,
|
|
g_test_init() will print an error and exit. This is to prevent no-op tests
|
|
from being executed, as g_assert() is commonly (erroneously) used in unit
|
|
tests, and is a no-op when compiled with `G_DISABLE_ASSERT`. Ensure your
|
|
tests are compiled without `G_DISABLE_ASSERT` defined.</doc>

<doc xml:space="preserve">Installs a non-error fatal log handler which can be

used to decide whether log messages which are counted

as fatal abort the program.
|
|
|
|
The use case here is that you are running a test case
|
|
that depends on particular libraries or circumstances
|
|
and cannot prevent certain known critical or warning
|
|
messages. So you install a handler that compares the
|
|
domain and message to precisely not abort in such a case.
|
|
|
|
Note that the handler is reset at the beginning of
|
|
any test case, so you have to set it inside each test
|
|
function which needs the special behavior.
|
|
|
|
This handler has no effect on g_error messages.
|
|
|
|
This handler also has no effect on structured log messages (using
|
|
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` and `-s testpath`) as parsed by g_test_init().
|
|
g_test_run_suite() or g_test_run() may only be called once in a
|
|
program.
|
|
|
|
In general, the tests and sub-suites within each suite are run in
|
|
the order in which they are defined. However, note that prior to
|
|
GLib 2.36, there was a bug in the `g_test_add_*`
|
|
functions which caused them to create multiple suites with the same
|
|
name, meaning that if you created tests "/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.
|
|

Note that timeout functions may be delayed, due to the processing of other

After each call to the timeout function, the time of the next

This internally creates a main loop source using g_timeout_source_new()

Note that timeout functions may be delayed, due to the processing of other

event sources. Thus they should not be relied on for precise timing.
|

After each call to the timeout function, the time of the next

timeout is recalculated based on the current time and the given interval
|
|
(it does not try to 'catch up' time lost in delays).

and attaches it to the global #GMainContext using g_source_attach(), so

the callback will be invoked in whichever thread is running that main

context. You can do these steps manually if you need greater control or to

use a custom main context.

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().
|

g_timeout_source_new_seconds() and attaches it to the main loop context

This function does not include compatibility

Hangul Jamo decomposition, as well as 'singleton'
|

decompositions which replace a character by a single

Note that the way Unicode decomposition pairs are

defined, it is guaranteed that @b would not decompose

further, but @a may itself decompose. To get the full

Since 2.10, this function allows to pass a negative @offset to
|
|
step backwards. It is usually worth stepping backwards from the end
|
|
instead of forwards if @offset is in the last fourth of the string,
|
|
since moving forward is about 3 times faster than moving backward.
|
|
|
|
Note that this function doesn't abort when reaching the end of @str.
|
|
Therefore you should be sure that @offset is within string boundaries
|
|
before calling that function. Call g_utf8_strlen() when unsure.
|
|
This limitation exists as this function is called frequently during
|
|
text rendering and therefore has to be as fast as possible.</doc>

<doc xml:space="preserve">Parses a #GVariant from a text representation.
|
|
|
|
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
|
|
produced by g_variant_print()".
|
|
|
|
There may be implementation specific restrictions on deeply nested values,
|
|
which would result in a %G_VARIANT_PARSE_ERROR_RECURSION error. #GVariant is
