Functions
This function is similar to g_malloc(), allocating (@n_blocks * @n_block_bytes) bytes, but care is taken to align the allocated memory to with the given alignment value. Additionally, it will detect possible overflow during multiplication.
This function is similar to g_aligned_alloc(), but it will also clear the allocated memory before returning it.
Frees the memory allocated by g_aligned_alloc().
Frees the memory pointed to by @mem, assuming it is has the given @size and

is returned.
Compare two strings, ignoring the case of ASCII characters.
Converts all upper case ASCII letters to lower case ASCII letters, with semantics that exactly match func@GLib.ascii_tolower.
Compare @s1 and @s2, ignoring the case of ASCII characters and any characters after the first @n in each string. If either string is less than @n bytes long, comparison will stop at the first nul byte encountered.
Converts all lower case ASCII letters to upper case ASCII letters, with semantics that exactly match func@GLib.ascii_toupper.
Convert a character to ASCII lower case. If the character is not an ASCII upper case letter, it is returned unchanged.
Convert a character to ASCII upper case. If the character is not an ASCII lower case letter, it is returned unchanged.

Find the position of the first bit set in @mask, searching from (but not including) @nth_bit upwards. Bits are numbered from 0 (least significant) to sizeof(#gulong) * 8 - 1 (31 or 63, usually). To start searching from the 0th bit, set @nth_bit to -1.
Find the position of the first bit set in @mask, searching from (but not including) @nth_bit downwards. Bits are numbered from 0 (least significant) to sizeof(#gulong) * 8 - 1 (31 or 63, usually). To start searching from the last bit, set @nth_bit to -1 or GLIB_SIZEOF_LONG * 8.
Gets the number of bits used to hold @number, e.g. if @number is 4, 3 bits are needed.
Creates a filename from a vector of elements using the correct separator for the current platform.
Behaves exactly like g_build_path(), but takes the path elements as a string array, instead of variadic arguments.
Gets the canonical file name from @filename. All triple slashes are turned into single slashes, and all ..
and .
s resolved against @relative_to.
Checks that the GLib library in use is compatible with the given version.
Sets a function to be called when the child indicated by @pid exits, at the priority @priority.
Creates a new child_watch source.
If @err or *@err is null, does nothing. Otherwise, calls g_error_free() on *@err and sets *@err to null.
Computes the checksum for a binary @data. This is a convenience wrapper for g_checksum_new(), g_checksum_get_string() and g_checksum_free().

Computes the HMAC for a binary @data. This is a convenience wrapper for g_hmac_new(), g_hmac_get_string() and g_hmac_unref().
Destroys the dataset, freeing all memory allocated, and calling any destroy functions set for data elements.
Calls the given function for each data element which is associated with the given location. Note that this function is NOT thread-safe. So unless @dataset_location can be protected from any modifications during invocation of this function, it should not be called.
Gets the data element corresponding to a #GQuark.
Removes an element, without calling its destroy notification function.
This is a variant of g_dgettext() that allows specifying a locale category instead of always using LC_MESSAGES
. See g_dgettext() for more information about how this functions differs from calling dcgettext() directly.
Compares two #gpointer arguments and returns true if they are equal. It can be passed to g_hash_table_new() as the @key_equal_func parameter, when using opaque pointers compared by pointer value as keys in a #GHashTable.
Converts a gpointer to a hash value. It can be passed to g_hash_table_new() as the @hash_func parameter, when using opaque pointers compared by pointer value as keys in a #GHashTable.
Compares the two #gdouble values being pointed to and returns true if they are equal. It can be passed to g_hash_table_new() as the @key_equal_func parameter, when using non-null pointers to doubles as keys in a #GHashTable.
Converts a pointer to a #gdouble to a hash value. It can be passed to g_hash_table_new() as the @hash_func parameter, It can be passed to g_hash_table_new() as the @hash_func parameter, when using non-null pointers to doubles as keys in a #GHashTable.
This function is a variant of g_dgettext() which supports a disambiguating message context. GNU gettext uses the '\004' character to separate the message context and message id in @msgctxtid. If 0 is passed as @msgidoffset, this function will fall back to trying to use the deprecated convention of using "|" as a separation character.
This function is a variant of g_dgettext() which supports a disambiguating message context. GNU gettext uses the '\004' character to separate the message context and message id in @msgctxtid.
Returns the value of the environment variable @variable in the provided list @envp.
Mark every file descriptor equal to or greater than @lowfd to be closed at the next execve()
or similar, as if via the FD_CLOEXEC
flag.
Gets a #GFileError constant based on the passed-in @err_no.
Returns the display basename for the particular filename, guaranteed to be valid UTF-8. The display name might not be identical to the filename, for instance there might be problems converting it to UTF-8, and some files can be translated in the display.
Converts a filename into a valid UTF-8 string. The conversion is not necessarily reversible, so you should keep the original around and use the return value of this function only for display purposes. Unlike g_filename_to_utf8(), the result is guaranteed to be non-null even if the filename actually isn't in the GLib file name encoding.
Converts an absolute filename to an escaped ASCII-encoded URI, with the path component following Section 3.3. of RFC 2396.
Reads the contents of the symbolic link @filename like the POSIX readlink()
function.
Returns true if any of the tests in the bitfield @test are true. For example, (G_FILE_TEST_EXISTS | G_FILE_TEST_IS_DIR)
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.
Locates the first executable named @program in the user's path, in the same way that execvp() would locate it. Returns an allocated string with the absolute path name, or null if the program is not found in the path. If @program is already an absolute path, returns a copy of
Formats a size (for example the size of a file) into a human readable string. Sizes are rounded to the nearest size prefix (kB, MB, GB) and are displayed rounded to the nearest tenth. E.g. the file size 3292528 bytes will be converted into the string "3.2 MB". The returned string is UTF-8, and may use a non-breaking space to separate the number and units, to ensure they aren’t separated when line wrapped.

Formats a size.
Gets a human-readable name for the application, as set by g_set_application_name(). This name should be localized if possible, and is intended for display to the user. Contrast with g_get_prgname(), which gets a non-localized name. If g_set_application_name() has not been called, returns the result of g_get_prgname() (which may be null if g_set_prgname() has also not been called).
Gets the character set for the current locale.
Gets the current directory.
Equivalent to the UNIX gettimeofday() function, but portable.
Gets the list of environment variables for the current process.
Gets the current user's home directory.
Return a name for the machine.
Computes a list of applicable locale names, which can be used to e.g. construct locale-dependent filenames or search paths. The returned list is sorted from most desirable to least desirable and always contains the default locale "C".
Computes a list of applicable locale names with a locale category name, which can be used to construct the fallback locale-dependent filenames or search paths. The returned list is sorted from most desirable to least desirable and always contains the default locale "C".
Returns a list of derived variants of @locale, which can be used to e.g. construct locale-dependent filenames or search paths. The returned list is sorted from most desirable to least desirable. This function handles territory, charset and extra locale modifiers. See man:setlocale for information about locales and their format.
Queries the system monotonic time.
Determine the approximate number of threads that the system will schedule simultaneously for this process. This is intended to be used as a parameter to g_thread_pool_new() for CPU bound tasks and similar cases.
Gets the name of the program. This name should not be localized, in contrast to g_get_application_name().
Gets the real name of the user. This usually comes from the user's entry in the passwd
file. The encoding of the returned string is system-defined. (On Windows, it is, however, always UTF-8.) If the real user name cannot be determined, the string "Unknown" is returned.
Queries the system wall-clock time.
Returns an ordered list of base directories in which to access system-wide configuration information.
Returns an ordered list of base directories in which to access system-wide application data.
Returns a base directory in which to store non-essential, cached data specific to particular user.
Returns a base directory in which to store user-specific application configuration information such as user preferences and settings.
Returns a base directory in which to access application data such as icons that is customized for a particular user.
Gets the user name of the current user. The encoding of the returned string is system-defined. On UNIX, it might be the preferred file name encoding, or something else, and there is no guarantee that it is even consistent on a machine. On Windows, it is always UTF-8.
Returns a directory that is unique to the current user on the local system.
Returns the full path of a special directory using its logical id.
Returns a base directory in which to store state files specific to particular user.
Tests if @hostname contains segments with an ASCII-compatible encoding of an Internationalized Domain Name. If this returns true, you should decode the hostname with g_hostname_to_unicode() before displaying it to the user.
Tests if @hostname is the string form of an IPv4 or IPv6 address. (Eg, "192.168.0.1".)
Tests if @hostname contains Unicode characters. If this returns true, you need to encode the hostname with g_hostname_to_ascii() before using it in non-IDN-aware contexts.
Converts @hostname to its canonical ASCII form; an ASCII-only string containing no uppercase letters and not ending with a trailing dot.
Converts @hostname to its canonical presentation form; a UTF-8 string in Unicode normalization form C, containing no uppercase letters, no forbidden characters, and no ASCII-encoded segments, and not ending with a trailing dot.
Adds a function to be called whenever there are no higher priority events pending.
Adds a function to be called whenever there are no higher priority events pending to the default main loop. The function is given the default idle priority, const@GLib.PRIORITY_DEFAULT_IDLE.
Removes the idle function with the given data.
Creates a new idle source.
Compares the two #gint64 values being pointed to and returns true if they are equal. It can be passed to g_hash_table_new() as the @key_equal_func parameter, when using non-null pointers to 64-bit integers as keys in a #GHashTable.
Compares the two #gint values being pointed to and returns true if they are equal. It can be passed to g_hash_table_new() as the @key_equal_func parameter, when using non-null pointers to integers as keys in a #GHashTable.
Returns a canonical representation for @string. Interned strings can be compared for equality by comparing the pointers, instead of using strcmp(). g_intern_static_string() does not copy the string, therefore @string must not be freed or modified.

Adds the #GIOChannel into the default main loop context with the given priority.
Creates a #GSource that's dispatched when @condition is met for the given @channel. For example, if condition is %G_IO_IN, the source will be dispatched when there's data available for reading.

).
Check whether the given @output_fd file descriptor supports ANSI color escape sequences.
Returns the currently firing source for this thread.
Returns the depth of the stack of calls to method@GLib.MainContext.dispatch on any #GMainContext in the current thread. That is, when called from the toplevel, it gives 0. When called from within a callback from method@GLib.MainContext.iteration (or method@GLib.MainLoop.run, etc.) it returns 1. When called from within a callback to a recursive call to method@GLib.MainContext.iteration, it returns 2. And so forth.
This function is similar to g_malloc0(), allocating (@n_blocks * @n_block_bytes) bytes, but care is taken to detect possible overflow during multiplication.
This function is similar to g_malloc(), allocating (@n_blocks * @n_block_bytes) bytes, but care is taken to detect possible overflow during multiplication.
Escapes text so that the markup parser will parse it verbatim. Less than, greater than, ampersand, etc. are replaced with the corresponding entities. This function would typically be used when writing out a file to be parsed with the markup parser.
Checks whether the allocator used by g_malloc() is the system's malloc implementation. If it returns true memory allocated with malloc() can be used interchangeably with memory allocated using g_malloc(). This function is useful for avoiding an extra copy of allocated memory returned by a non-GLib-based API.
GLib used to support some tools for memory profiling, but this no longer works. There are many other useful tools for memory profiling these days which can be used instead.
This function used to let you override the memory allocation function. However, its use was incompatible with the use of global constructors in GLib and GIO, because those use the GLib allocators before main is reached. Therefore this function is now deprecated and is just a stub.
Create a directory if it doesn't already exist. Create intermediate parent directories as needed, too.
Creates a temporary directory. See the mkdtemp() documentation on most UNIX-like systems.
Opens a temporary file. See the mkstemp() documentation on most UNIX-like systems.

. The directory component of /
is /
.
Returns true if the given @file_name is an absolute file name. Note that this is a somewhat vague concept on Windows.
Returns a pointer into @file_name after the root component, i.e. after the "/" in UNIX or "C:\" under Windows. If @file_name is not an absolute path it returns null.
Matches a string against a compiled pattern.
Matches a string against a pattern given as a string.
Matches a string against a compiled pattern.
Polls @fds, as with the poll() system call, but portably. (On systems that don't have poll(), it is emulated using select().) This is used internally by #GMainContext, but it can be called directly if you need to block until a file descriptor is ready, but don't want to run the full main loop.
This is just like the standard C man:qsort(3) function, but the comparison routine accepts a user data argument (like man:qsort_r(3)).
Gets the #GQuark identifying the given (static) string. If the string does not currently have an associated #GQuark, a new #GQuark is created, linked to the given string.

Internal function used to print messages from the public func@GLib.return_if_fail and func@GLib.return_val_if_fail macros.
Sets a human-readable name for the application. This name should be localized if possible, and is intended for display to the user. Contrast with g_set_prgname(), which sets a non-localized name. g_set_prgname() will be called automatically by gtk_init(), but g_set_application_name() will not.
Sets the name of the program. This name should not be localized, in contrast to g_set_application_name().

Frees a linked list of memory blocks of structure type @type.
Gets the smallest prime number from a built-in array of primes which is larger than @num. This is used within GLib to calculate the optimum size of a #GHashTable.
An old name for g_spawn_check_wait_status(), deprecated because its name is misleading.
Set @error if @wait_status indicates the child exited abnormally (e.g. with a nonzero exit code, or via a fatal signal).
On some platforms, notably Windows, the #GPid type represents a resource which must be closed to prevent resource leaking. g_spawn_close_pid() is provided for this purpose. It should be used on all platforms, even though it doesn't do anything under UNIX.
A simple version of g_spawn_async() that parses a command line with g_shell_parse_argv() and passes it to g_spawn_async().

on systems which have it, and emulates it otherwise. Appends nul-terminated @src string to @dest, guaranteeing nul-termination for @dest. The total size of @dest won't exceed @dest_size.
Portability wrapper that calls strlcpy()
on systems which have it, and emulates strlcpy()
otherwise. Copies @src to @dest; @dest is guaranteed to be nul-terminated; @src must be nul-terminated;
Checks if a search conducted for @search_term should match
A case-insensitive string comparison, corresponding to the standard strncasecmp()
function on platforms which support it. It is similar to func@GLib.strcasecmp except it only compares the first @n characters of the strings.
Duplicates the first @n bytes of a string, returning a newly-allocated buffer @n + 1 bytes long which will always be nul-terminated. If @str is less than @n bytes long the buffer is padded with nuls. If @str is NULL
it returns NULL
.
Reverses all of the bytes in a string. For example, g_strreverse ("abcdef")
will result in "fedcba".
Searches the string @haystack for the last occurrence of the string @needle, limiting the length of the search to @haystack_len.
Splits @string into a number of tokens not containing any of the characters in @delimiters. A token is the (possibly empty) longest string that does not contain any of the characters in @delimiters. If @max_tokens is reached, the remainder is appended to the last token.

Attempt to disable system crash reporting infrastructure.
Indicates that a message with the given @log_domain and @log_level, with text matching @pattern, is expected to be logged.

Gets the pathname of the directory containing test files of the type specified by @file_type.
Gets the test path for the test currently being run.
Indicates that a test failed because of some incomplete functionality. This function can be called multiple times from the same test.
Installs a non-error fatal log handler which can be used to decide whether log messages which are counted as fatal abort the program.
Enqueue a pointer to be released with g_free() during the next teardown phase. This is equivalent to calling g_test_queue_destroy() with a destroy callback of g_free().

Get a reproducible random integer number.
Get a reproducible random integer number out of a specified range, see g_test_rand_int() for details on test case random numbers.
Runs all tests under the toplevel suite which can be retrieved with g_test_get_root(). Similar to g_test_run_suite(), the test cases to be run are filtered according to test path arguments (-p testpath
and -s testpath
) as parsed by g_test_init(). g_test_run_suite() or g_test_run() may only be called once in a program.
Changes the behaviour of the various g_assert_*()
macros, g_test_assert_expected_messages() and the various g_test_trap_assert_*()
macros to not abort to program, but instead call g_test_fail() and continue. (This also changes the behavior of g_test_fail() so that it will not cause the test program to abort after completing the failed test.)
Returns true (after g_test_init() has been called) if the test program is running under g_test_trap_subprocess().
Set the summary for a test, which describes what the test checks, and how it goes about checking it. This may be included in test report output, and is useful documentation for anyone reading the source code or modifying a test in future. It must be a single line.
Get the number of seconds since the last start of the timer with g_test_timer_start().
Report the last result of g_test_timer_elapsed().

Sets a function to be called at regular intervals, with the given priority. 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. The @notify function is called when the timeout is destroyed. The first call to the function will be at the end of the first @interval.
Sets a function to be called after @interval milliseconds have elapsed, with the default priority, const@GLib.PRIORITY_DEFAULT.
Sets a function to be called at regular intervals, with @priority.
This function behaves like func@GLib.timeout_add_once but with a range in seconds.

Attempts to allocate @n_bytes, initialized to 0's, and returns null on failure. Contrast with g_malloc0(), which aborts the program on failure.
This function is similar to g_try_malloc0(), allocating (@n_blocks * @n_block_bytes) bytes, but care is taken to detect possible overflow during multiplication.
This function is similar to g_try_malloc(), allocating (@n_blocks * @n_block_bytes) bytes, but care is taken to detect possible overflow during multiplication.
Attempts to realloc @mem to a new size, @n_bytes, and returns null on failure. Contrast with g_realloc(), which aborts the program on failure.
This function is similar to g_try_realloc(), allocating (@n_blocks * @n_block_bytes) bytes, but care is taken to detect possible overflow during multiplication.
Determines the break type of @c. @c should be a Unicode character (to derive a character from UTF-8 encoded text, use g_utf8_get_char()). The break type is used to find word and line breaks ("text boundaries"), Pango implements the Unicode boundary resolution algorithms and normally you would use a function such as pango_break() instead of caring about break types yourself.
Determines the canonical combining class of a Unicode character.
Determines the numeric value of a character as a decimal digit.
Looks up the #GUnicodeScript for a particular character (as defined by Unicode Standard Annex \#24). No check is made for @ch being a valid Unicode character; if you pass in invalid character, the result is undefined.
Determines whether a character is alphanumeric. Given some UTF-8 text, obtain a character value with g_utf8_get_char().
Determines whether a character is alphabetic (i.e. a letter). Given some UTF-8 text, obtain a character value with g_utf8_get_char().
Determines whether a character is a control character. Given some UTF-8 text, obtain a character value with g_utf8_get_char().
Determines if a given character is assigned in the Unicode standard.
Determines whether a character is numeric (i.e. a digit). This covers ASCII 0-9 and also digits in other languages/scripts. Given some UTF-8 text, obtain a character value with g_utf8_get_char().
Determines whether a character is printable and not a space (returns false for control characters, format characters, and spaces). g_unichar_isprint() is similar, but returns true for spaces. Given some UTF-8 text, obtain a character value with g_utf8_get_char().
Determines whether a character is a lowercase letter. Given some UTF-8 text, obtain a character value with g_utf8_get_char().
Determines whether a character is a mark (non-spacing mark, combining mark, or enclosing mark in Unicode speak). Given some UTF-8 text, obtain a character value with g_utf8_get_char().

Determines whether a character is punctuation or a symbol. Given some UTF-8 text, obtain a character value with g_utf8_get_char().
Determines whether a character is a space, tab, or line separator (newline, carriage return, etc.). Given some UTF-8 text, obtain a character value with g_utf8_get_char().
Determines if a character is titlecase. Some characters in Unicode which are composites, such as the DZ digraph have three case variants instead of just two. The titlecase form is used at the beginning of a word where only the first letter is capitalized. The titlecase form of the DZ digraph is U+01F2 LATIN CAPITAL LETTTER D WITH SMALL LETTER Z.
Determines if a character is uppercase.
Determines if a character is typically rendered in a double-width cell.
Determines if a character is typically rendered in a double-width cell under legacy East Asian locales. If a character is wide according to g_unichar_iswide(), then it is also reported wide with this function, but the converse is not necessarily true. See the Unicode Standard Annex #11 for details.
Determines if a character is a hexadecimal digit.
Determines if a given character typically takes zero width when rendered. The return value is true for all non-spacing and enclosing marks (e.g., combining accents), format characters, zero-width space, but not U+00AD SOFT HYPHEN.
Converts a character to lower case.
Converts a character to the titlecase.
Converts a character to uppercase.
Classifies a Unicode character by type.
Checks whether @ch is a valid Unicode character. Some possible integer values of @ch will not be valid. 0 is considered a valid character, though it's normally a string terminator.
Determines the numeric value of a character as a hexadecimal digit.
Sets a function to be called when the IO condition, as specified by
Sets a function to be called when the IO condition, as specified by
Creates a #GSource to watch for a particular I/O condition on a file descriptor.
Control the non-blocking state of the given file descriptor, according to @nonblock. On most systems this uses %O_NONBLOCK, but on some older ones may use %O_NDELAY.
A convenience function for g_unix_signal_source_new(), which attaches to the default #GMainContext. You can remove the watch using g_source_remove().
Create a #GSource that will be dispatched upon delivery of the UNIX signal @signum. In GLib versions before 2.36, only SIGHUP
, SIGINT
, SIGTERM
can be monitored. In GLib 2.36, SIGUSR1
and SIGUSR2
were added. In GLib 2.54, SIGWINCH
was added.
Converts a string into a form that is independent of case. The result will not correspond to any particular case, but can be compared for equality or ordered with the results of calling g_utf8_casefold() on other strings.
Compares two strings for ordering using the linguistically correct rules for the setlocale. When sorting a large number of strings, it will be significantly faster to obtain collation keys with g_utf8_collate_key() and compare the keys with strcmp() when sorting instead of sorting the original strings.
Converts a string into a collation key that can be compared with other collation keys produced by the same function using strcmp().
Converts a string into a collation key that can be compared with other collation keys produced by the same function using strcmp().
Finds the start of the next UTF-8 character in the string after @p.
Given a position @p with a UTF-8 encoded string @str, find the start of the previous UTF-8 character starting before @p. Returns null if no UTF-8 characters are present in @str before @p.
Converts a sequence of bytes encoded as UTF-8 to a Unicode character.
Convert a sequence of bytes encoded as UTF-8 to a Unicode character. This function checks for incomplete characters, for invalid characters such as characters that are out of the range of Unicode, and for overlong encodings of valid characters.
If the provided string is valid UTF-8, return a copy of it. If not, return a copy in which bytes that could not be interpreted as valid Unicode are replaced with the Unicode replacement character (U+FFFD).
Converts a string into canonical form, standardizing such issues as whether a character with an accent is represented as a base character and combining accent or as a single precomposed character. The string has to be valid UTF-8, otherwise null is returned. You should generally call g_utf8_normalize() before comparing two Unicode strings.
Converts from an integer character offset to a pointer to a position within the string.
Converts from a pointer to position within a string to an integer character offset.
Finds the previous UTF-8 character in the string before @p.
Finds the leftmost occurrence of the given Unicode character in a UTF-8 encoded string, while limiting the search to @len bytes. If @len is -1, allow unbounded search.
Converts all Unicode characters in the string that have a case to lowercase. The exact manner that this is done depends on the current locale, and may result in the number of characters in the string changing.
Computes the length of the string in characters, not including the terminating nul character. If the @max'th byte falls in the middle of a character, the last (partial) character is not counted.
Like the standard C strncpy() function, but copies a given number of characters instead of a given number of bytes. The @src string must be valid UTF-8 encoded text. (Use g_utf8_validate() on all text before trying to use UTF-8 utility functions with it.)
Find the rightmost occurrence of the given Unicode character in a UTF-8 encoded string, while limiting the search to @len bytes. If @len is -1, allow unbounded search.
Reverses a UTF-8 string. @str must be valid UTF-8 encoded text. (Use g_utf8_validate() on all text before trying to use UTF-8 utility functions with it.)
Converts all Unicode characters in the string that have a case to uppercase. The exact manner that this is done depends on the current locale, and may result in the number of characters in the string increasing. (For instance, the German ess-zet will be changed to SS.)
Copies a substring out of a UTF-8 encoded string. The substring will contain @end_pos - @start_pos characters.
Cuts off the middle of the string, preserving half of @truncate_length characters at the beginning and half at the end.
Parses the string @str and verify if it is a UUID.
Generates a random UUID (RFC 4122 version 4) as a string. It has the same randomness guarantees as #GRand, so must not be used for cryptographic purposes such as key generation, nonces, salts or one-time pads.
Internal function used to print messages from the public func@GLib.warn_if_reached and func@GLib.warn_if_fail macros.
