Quark

A GQuark is a non-zero integer which uniquely identifies a particular string.

A GQuark value of zero is associated to NULL.

Given either the string or the GQuark identifier it is possible to retrieve the other.

Quarks are used for both datalist-and-dataset.html.

To create a new quark from a string, use func@GLib.quark_from_string or func@GLib.quark_from_static_string.

To find the string corresponding to a given GQuark, use func@GLib.quark_to_string.

To find the GQuark corresponding to a given string, use func@GLib.quark_try_string.

Another use for the string pool maintained for the quark functions is string interning, using func@GLib.intern_string or func@GLib.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().
