msg_set_queue - Set information in the message queue data structure

SYNOPSIS
       bool msg_set_queue (resource  $queue, array  $data)

DESCRIPTION
       msg_set_queue(3)  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.

	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.

PARAMETERS
	      o $queue
		- Message queue resource handle

	      o $data
		- You specify the values you require by setting the value of the keys that you require in the $data array.

RETURN VALUES
