/**
 * Description
 * The GQueue structure and its associated functions provide a standard
 * queue data structure. Internally, GQueue uses the same data structure as
 * GList to store elements.
 * The data contained in each element can be either integer values, by using one
 * of the
 * Type Conversion Macros,
 * or simply pointers to any type of data.
 * To create a new GQueue, use g_queue_new().
 * To initialize a statically-allocated GQueue, use G_QUEUE_INIT or
 * g_queue_init().
 * To add elements, use g_queue_push_head(), g_queue_push_head_link(),
 * g_queue_push_tail() and g_queue_push_tail_link().
 * To remove elements, use g_queue_pop_head() and g_queue_pop_tail().
 * To free the entire queue, use g_queue_free().
