<para>
<function>msg_get_queue</function> returns an id that can be used to
access the System V message queue with the given
<parameter>key</parameter>. The first call creates the message queue with
the optional <parameter>perms</parameter> (default: 0666).
A second call to <function>msg_get_queue</function> for the same
<parameter>key</parameter> will return a different message queue
identifier, but both identifiers access the same underlying message
queue.
If the message queue already exists, the <parameter>perms</parameter>
will be ignored.
