const gchar* g_type_name ( GType type )
Get the unique name that is assigned to a type ID. Note that this
function (like all other GType API) cannot cope with invalid type
G_TYPE_INVALID may be passed to this function, as may be any
other validly registered type ID, but randomized type IDs should
not be passed in and will most likely lead to a crash.
Type to return name for.
