                                 msg_set_queue

   (PHP 4 >= 4.3.0)
   msg_set_queue --  Set information in the message queue data structure

Description

   bool msg_set_queue ( int queue, array data)

   msg_set_queue() 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 data array.

   Changing the data structure will require that PHP be running as the
   same user that created the 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.

   See also: msg_remove_queue(), msg_receive(), msg_stat_queue() and
   msg_set_queue().
