/**
 * GRefString:
 *
 * A typedef for a reference-counted string. A pointer to a #GRefString can be
 * treated like a standard `char*` array by all code, but can additionally have
 * `g_ref_string_*()` methods called on it. `g_ref_string_*()` methods cannot be
 * called on `char*` arrays not allocated using g_ref_string_new().
 *
 * If using #GRefString with autocleanups, g_autoptr() must be used rather than
 * g_autofree(), so that the reference counting metadata is also freed.
 *
 * Since: 2.58
