msg_send - Send a message to a message queue

SYNOPSIS

       bool msg_send (resource	$queue, int  $msgtype, mixed  $message, [bool  $serialize = true], [bool  $blocking = true], [int  &$errorcode])

DESCRIPTION

       msg_send(3) sends a $message of type $msgtype (which MUST be greater than 0) to the message queue specified by $queue.

PARAMETERS

	      o $queue
		-

	      o $msgtype
		-

	      o $message
		-

	      o $serialize
		-  The optional $serialize controls how the $message is sent. $serialize defaults to TRUE which means that the $message is serial-
		ized using the same mechanism as the session module before being sent to the queue. This allows complex arrays and objects  to	be
		sent to other PHP scripts, or if you are using the WDDX serializer, to any WDDX compatible client.

	      o $blocking
		-  If  the message is too large to fit in the queue, your script will wait until another process reads messages from the queue and
		frees enough space for your message to be sent. This is called blocking; you can prevent blocking by setting the optional  $block-
		ing  parameter	to FALSE, in which case msg_send(3) will immediately return FALSE if the message is too big for the queue, and set
		the optional $errorcode to MSG_EAGAIN, indicating that you should try to send your message again a little later on.

	      o $errorcode
		-

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

	Upon successful completion the message queue data structure is updated as follows: $msg_lspid is set to  the  process-ID  of  the  calling
       process, $msg_qnum is incremented by 1 and $msg_stime is set to the current time.
