tt_pattern_arg_add(library call)	      tt_pattern_arg_add(library call)

NAME
       tt_pattern_arg_add -- add an argument to	a pattern

SYNOPSIS
       #include	<Tt/tt_c.h>
       Tt_status tt_pattern_arg_add(
       Tt_pattern p,
       Tt_mode n,
       const char *vtype,
       const char *value);

DESCRIPTION
       The tt_pattern_arg_add function adds an argument	to a pattern.  The ap-
       plication must add pattern arguments before it  registers  the  pattern
       with the	ToolTalk service.

       The  p  argument	 is the	opaque handle for the pattern involved in this
       operation The n argument	specifies  who	(sender,  handler,  observers)
       writes and reads	a message argument.  The following modes are defined:

       TT_IN	 The argument is written by the	sender and read	by the handler
		 and any observers.

       TT_OUT	 The argument is written by the	handler	and read by the	sender
		 and any reply observers.

       TT_INOUT	 The  argument	is  written  by	the sender and the handler and
		 read by all.

       The vtype argument describes the	type of	 argument  data	 being	added.
       The  type  ALL  matches any argument value type.	 The value argument is
       the value to fill in.  This value must be an unsigned character string.
       A NULL matches any value.

RETURN VALUE
       Upon successful completion, the tt_pattern_arg_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.
