DESCRIPTION
     The tt_pattern_class_add()	function  adds	a  value  to  the
     class information for the specified pattern.

     If	the class is TT_REQUEST, the sending  process  expects	a
     reply to the message.

     If	the class is TT_NOTICE,	 the  sending  process	does  not
     expect a reply to the message.

     The p argument is a unique	handle	for  a	message	 pattern.
     This   handle  is	returned  after	 tt_pattern_create(3)  is
     called.  The c argument indicates whether the receiving pro-
     cess  is  to take action after the	message	is received.  The
     following values are defined:

	TT_NOTICE
		A notice of an event.  The sender does	not  want
		feedback on this message.

	TT_REQUEST
		A request for  some  action  to	 be  taken.   The
		sender	must  be notified of progress, success or
		failure, and must receive any return values.

RETURN VALUE
     Upon successful completion, the tt_pattern_class_add() func-
     tion  returns the status of the operation as one of the fol-
     lowing Tt_status values:

	TT_OK	The operation completed	successfully.

	TT_ERR_NOMP
		The ttsession(1) process is not	running	 and  the
		ToolTalk service cannot	restart	it.
