Static functions

atexit

void atexit(GVoidFunc func)

Specifies a function to be called at normal program termination.

basename

string basename(string fileName)

Gets the name of the file without any leading directory components. It returns a pointer into the given file name string.

bitNthLsf

int bitNthLsf(gulong mask, int nthBit)

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.

bitNthMsf

int bitNthMsf(gulong mask, int nthBit)

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.

bitStorage

uint bitStorage(gulong number)

Gets the number of bits used to hold number, e.g. if number is 4, 3 bits are needed.

buildFilename

string buildFilename(string[] firstElement)

Behaves exactly like g_build_filename(), but takes the path elements as a string array, instead of varargs. This function is mainly meant for language bindings.

buildPath

string buildPath(string separator, string[] firstElement)

Behaves exactly like g_build_path(), but takes the path elements as a string array, instead of varargs. This function is mainly meant for language bindings.

canonicalizeFilename

string canonicalizeFilename(string filename, string relativeTo)

Gets the canonical file name from filename. All triple slashes are turned into single slashes, and all .. and .s resolved against relative_to.

environGetenv

string environGetenv(string[] envp, string variable)

Returns the value of the environment variable variable in the provided list envp.

environSetenv

string[] environSetenv(string[] envp, string variable, string value, bool overwrite)

Sets the environment variable variable in the provided list envp to value.

environUnsetenv

string[] environUnsetenv(string[] envp, string variable)

Removes the environment variable variable from the provided environment envp.

findProgramInPath

string findProgramInPath(string program)

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 program if program exists and is executable, and NULL otherwise.

formatSize

string formatSize(ulong size)

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.

formatSizeForDisplay

string formatSizeForDisplay(long size)

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 "3.1 MB".

formatSizeFull

string formatSizeFull(ulong size, GFormatSizeFlags flags)

Formats a size.

getApplicationName

string getApplicationName()

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).

getCurrentDir

string getCurrentDir()

Gets the current directory.

getEnviron

string[] getEnviron()

Gets the list of environment variables for the current process.

getHomeDir

string getHomeDir()

Gets the current user's home directory.

getHostName

string getHostName()

Return a name for the machine.

getOsInfo

string getOsInfo(string keyName)

Get information about the operating system.

getPrgname

string getPrgname()

Gets the name of the program. This name should not be localized, in contrast to g_get_application_name().

getRealName

string getRealName()

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.

getSystemConfigDirs

string[] getSystemConfigDirs()

Returns an ordered list of base directories in which to access system-wide configuration information.

getSystemDataDirs

string[] getSystemDataDirs()

Returns an ordered list of base directories in which to access system-wide application data.

getTmpDir

string getTmpDir()

Gets the directory to use for temporary files.

getUserCacheDir

string getUserCacheDir()

Returns a base directory in which to store non-essential, cached data specific to particular user.

getUserConfigDir

string getUserConfigDir()

Returns a base directory in which to store user-specific application configuration information such as user preferences and settings.

getUserDataDir

string getUserDataDir()

Returns a base directory in which to access application data such as icons that is customized for a particular user.

getUserName

string getUserName()

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.

getUserRuntimeDir

string getUserRuntimeDir()

Returns a directory that is unique to the current user on the local system.

getUserSpecialDir

string getUserSpecialDir(GUserDirectory directory)

Returns the full path of a special directory using its logical id.

getenv

string getenv(string variable)

Returns the value of an environment variable.

listenv

string[] listenv()

Gets the names of all variables set in the environment.

nullifyPointer

void nullifyPointer(void** nullifyLocation)

Set the pointer at the specified location to NULL.

parseDebugString

uint parseDebugString(string string_, GDebugKey[] keys)

Parses a string containing debugging options into a guint containing bit flags. This is used within GDK and GTK+ to parse the debug options passed on the command line or through environment variables.

pathGetBasename

string pathGetBasename(string fileName)

Gets the last component of the filename.

pathGetDirname

string pathGetDirname(string fileName)

Gets the directory components of a file name. For example, the directory component of /usr/bin/test is /usr/bin. The directory component of / is /.

pathIsAbsolute

bool pathIsAbsolute(string fileName)

Returns TRUE if the given file_name is an absolute file name. Note that this is a somewhat vague concept on Windows.

pathSkipRoot

string pathSkipRoot(string fileName)

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.

qsortWithData

void qsortWithData(void* pbase, int totalElems, size_t size, GCompareDataFunc compareFunc, void* userData)

This is just like the standard C qsort() function, but the comparison routine accepts a user data argument.

reloadUserSpecialDirsCache

void reloadUserSpecialDirsCache()

Resets the cache used for g_get_user_special_dir(), so that the latest on-disk version is used. Call this only if you just changed the data on disk yourself.

setApplicationName

void setApplicationName(string applicationName)

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.

setPrgname

void setPrgname(string prgname)

Sets the name of the program. This name should not be localized, in contrast to g_set_application_name().

setenv

bool setenv(string variable, string value, bool overwrite)

Sets an environment variable. On UNIX, both the variable's name and value can be arbitrary byte strings, except that the variable's name cannot contain '='. On Windows, they should be in UTF-8.

spacedPrimesClosest

uint spacedPrimesClosest(uint num)

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 glib.HashTable

unsetenv

void unsetenv(string variable)

Removes an environment variable from the environment.
