tt_pattern_arg_add(3)  C LIBRARY FUNCTIONS  tt_pattern_arg_add(3)

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 pat-
     tern.   The application 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()  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.

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