<span class="function"><strong>msg_get_queue()</strong></span> returns an id that can be used to
access the System V message queue with the given
<em><code class="parameter">key</code></em>. The first call creates the message queue with
the optional <em><code class="parameter">perms</code></em>.
A second call to <span class="function"><strong>msg_get_queue()</strong></span> for the same
<em><code class="parameter">key</code></em> will return a different message queue
identifier, but both identifiers access the same underlying message
queue.
