tt_pattern_class_add(library call)	    tt_pattern_class_add(library call)

NAME
       tt_pattern_class_add -- add a value to the class	information for	a pat-
       tern

SYNOPSIS
       #include	<Tt/tt_c.h>
       Tt_status tt_pattern_class_add(
       Tt_pattern p,
       Tt_class	c);

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 indi-
       cates whether the receiving process 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 function returns
       the status of the operation as one of the following Tt_status values:

       TT_OK	 The operation completed successfully.

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

       TT_ERR_POINTER
		 The pointer passed does not point to an object	of the correct
		 type for this operation.
