<!-- ##### SECTION Title ##### -->
Double-ended Queues

<!-- ##### SECTION Short_Description ##### -->
double-ended queue data structure.

<!-- ##### SECTION Long_Description ##### -->
<para>
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.  
</para>
<para>
The data contained in each element can be either integer values, by using one
of the
<link linkend="glib-Type-Conversion-Macros">Type Conversion Macros</link>,
or simply pointers to any type of data.
</para>
<para>
To create a new #GQueue, use g_queue_new().
</para>
<para>
To add elements, use g_queue_push_head(), g_queue_push_head_link(), 
g_queue_push_tail() and g_queue_push_tail_link().
</para>
<para>
To remove elements, use g_queue_pop_head() and g_queue_pop_tail().
</para>
<para>
To free the entire queue, use g_queue_free().
</para>
