+ * 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
