#### Description

    typedef guint32 GQuark

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 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()`.
