tt_pattern_xarg_add(3) C LIBRARY FUNCTIONS tt_pattern_xarg_add(3)

NAME
     tt_pattern_xarg_add - add a new argument with an interpreted
     XDR value to a pattern object

SYNOPSIS
     #include <Tt/tt_c.h>

     Tt_status tt_pattern_xarg_add(Tt_pattern m,
				   Tt_mode n,
				   const char *vtype,
				   xdrproc_t xdr_proc,
				   void	*value);

DESCRIPTION
     The tt_pattern_xarg_add() function	adds a new argument  with
     an	interpreted XDR	value to a pattern object.

     The m argument is the opaque handle for the pattern involved
     in	 this  operation.   The	n argument specifies who (sender,
     handler, observers) writes	and  reads  a  pattern	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 xdr_proc argument points to the XDR procedure to
     be	used to	serialize the data  pointed  to	 by  value.   The
     value argument is the data	to be serialized.

RETURN VALUE
     Upon successful completion, the tt_pattern_xarg_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_MODE
		The specified Tt_mode is invalid.

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

	TT_ERR_POINTER
