<para>
<function>msg_set_queue</function> allows you to change the values of the
msg_perm.uid, msg_perm.gid, msg_perm.mode and msg_qbytes fields of the
underlying message queue data structure.
You specify the values you require by setting the value of the keys that
you require in the <parameter>data</parameter> array.
</para>
<para>
Changing the data structure will require that PHP be running as the same
user that created the queue, owns the queue (as determined by the
existing msg_perm.xxx fields), or be running with root privileges.
root privileges are required to raise the msg_qbytes values above the
system defined limit.
