Quark

Quarks are associations between strings and integer identifiers. Given either the string or the GQuark identifier it is possible to retrieve the other.

Quarks are used for both Datasets and Keyed Data Lists.

To create a new quark from a string, use g_quark_from_string() or g_quark_from_static_string().

To find the string corresponding to a given GQuark, use g_quark_to_string().

To find the GQuark corresponding to a given string, use g_quark_try_string().

Another use for the string pool maintained for the quark functions is string interning, using g_intern_string() or g_intern_static_string(). An interned string is a canonical representation for a string. One important advantage of interned strings is that they can be compared for equality by a simple pointer comparison, rather than using strcmp().

Static functions

fromStaticString GQuark fromStaticString(string string): 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. Note that this function is identical to g_quark_from_string() except that if a new GQuark is created the string itself is used rather than a copy. This saves memory, but can only be used if the string will always exist. It can be used with statically allocated strings in the main program, but not with statically allocated memory in dynamically loaded modules, if you expect to ever unload the module again (e.g. do not use this function in GTK+ theme engines).
fromString GQuark fromString(string string): Gets the GQuark identifying the given string. If the string does not currently have an associated GQuark, a new GQuark is created, using a copy of the string.
gInternStaticString string gInternStaticString(string string): 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. Since 2.10
gInternString string gInternString(string string): Returns a canonical representation for string. Interned strings can be compared for equality by comparing the pointers, instead of using strcmp(). Since 2.10
toString string toString(GQuark quark): Gets the string associated with the given GQuark.
tryString GQuark tryString(string string): Gets the GQuark associated with the given string, or 0 if string is NULL or it has no associated GQuark. If you want the GQuark to be created if it doesn't already exist, use g_quark_from_string() or g_quark_from_static_string().
