The "GDesktopEntry" parser is intended to parse files written to
the Desktop
Entry Specification. It supports deserialization of
desktop entries from files and in-memory data. Desktop entries
are used for a variety of things including menus, application
MIME type registration, and launchers.
To load an existing desktop entry from a data directory (as
returned by g_get_user_data_dir() and g_get_system_data_dirs())
use g_desktop_entry_new_from_data_dirs(). To load an existing
desktop entry from an arbitrary location on the file system use
g_desktop_entry_new_from_file(). If the desktop entry is already
in memory use g_desktop_entry_new_from_data(). Once the desktop
entry is loaded its keys can be queried using the g_desktop_entry_get
family of functions.
To create a new desktop entry first call g_desktop_entry_new().
Then, call the g_desktop_entry_set family of functions. Next,
call g_desktop_entry_to_data() to output the desktop entry to
a byte array, which can be written to disk or sent over a
network. Finally, call g_desktop_entry_free() to deallocate the
#GDesktopEntry object returned by g_desktop_entry_new().
serializes and deserializes a desktop entry.

Error codes returned by desktop entry parsing.
@G_DESKTOP_ENTRY_ERROR_UNKNOWN_ENCODING: text being parsed is not UTF-8 and
cannot be guessed.
@G_DESKTOP_ENTRY_ERROR_BAD_START_GROUP: desktop entry does not start with a
legal start group.
@G_DESKTOP_ENTRY_ERROR_PARSE: desktop entry is empty or contains invalid
data.
@G_DESKTOP_ENTRY_ERROR_NOT_FOUND: valid desktop entry could not be found.
@G_DESKTOP_ENTRY_ERROR_KEY_NOT_FOUND: desktop entry does not have requested
key.
@G_DESKTOP_ENTRY_ERROR_GROUP_NOT_FOUND: desktop entry does not have requested
group
@G_DESKTOP_ENTRY_ERROR_INVALID_VALUE: desktop entry contains key which has
value that cannot be validated.
#GDesktopEntry supports a few flags for tweaking performance during
deserialization. #G_DESKTOP_ENTRY_DISCARD_COMMENTS and
#G_DESKTOP_ENTRY_DISCARD_TRANSLATIONS will reduce memory footprint,
and #G_DESKTOP_ENTRY_GENERATE_LOOKUP_MAP will increase key lookup speed.
@G_DESKTOP_ENTRY_NONE: use parser defaults
@G_DESKTOP_ENTRY_DISCARD_COMMENTS: Discard all lines that are blank
or start with "#".
@G_DESKTOP_ENTRY_DISCARD_TRANSLATIONS: Only retain translations that
are returned by g_get_language_names().
@G_DESKTOP_ENTRY_GENERATE_LOOKUP_MAP: Generate a lookup map for key names to make lookups constant time at the cost of more memory.

internally for optimizing the match algorithm.
@G_MATCH_ALL: a general pattern.
@G_MATCH_ALL_TAIL: a general pattern which contains a fixed part matching
the end of the string.
@G_MATCH_HEAD: a pattern matching every string with a certain prefix.
@G_MATCH_TAIL: a pattern matching every string with a certain suffix.
@G_MATCH_EXACT: a pattern matching exactly one string.
@G_MATCH_LAST:
Specifies the type of function passed to g_set_warning_handler().
@str: the warning message.
Error domain for desktop entry parsing. Errors in this domain will
be from the #GDesktopEntryError enumeration. See #GError for information on
error domains.
One of %G_IO_CHANNEL_UNIX_LINE_TERM, %G_IO_CHANNEL_DOS_LINE_TERM,
or %G_IO_CHANNEL_MACINTOSH_LINE_TERM (unimplemented)
depending on the system type.
Encoding for nonbuffered IO. With this encoding, data must be
read using g_io_channel_read_chars(); the other functions will
not work.

The log domain used for messages logged by GLib itself.
Adds a file descriptor to be polled.
This is usually combined with g_source_add() to add an event source.
The event source's check function will typically test the revents
field in the #GPollFD struct and return TRUE if events need to be processed.
@fd: a #GPollFD, which is a file descriptor together with a bitwise
combination of #GIOCondition flags determining which events to poll for.
@priority: the priority of the poll, which should be the same as the priority
used for g_source_add() to ensure that the file descriptor is polled whenever
the results may be needed.
See #G_PRIORITY_DEFAULT, #G_PRIORITY_DEFAULT_IDLE, #G_PRIORITY_HIGH,
#G_PRIORITY_HIGH_IDLE, and #G_PRIORITY_LOW.
@thread:
@Returns:
@loop:
Removes a file descriptor from the list being polled.
@fd: the #GPollFD to remove.
@Returns:
Checks if the given memory has already been freed. If it has it outputs
a warning message.
To use this function you must configure glib with the flag
'--enable-mem-check=yes' before compiling.
@mem: the memory to check.
@Returns:
@regex:
Gets the file attributes.
This is the st_mode field from the
stat structure. See the stat()
documentation.
@filename: the file name.
@Returns: the file attributes.
