tt_pattern_barg_add(library call)	     tt_pattern_barg_add(library call)

NAME
       tt_pattern_barg_add  --	add an argument	with a value that contains em-
       bedded nulls to a pattern

SYNOPSIS
       #include	<Tt/tt_c.h>
       Tt_status tt_pattern_barg_add(
       Tt_pattern m,
       Tt_mode n,
       const char *vtype,
       const unsigned char *value,
       int len);

DESCRIPTION
       The tt_pattern_barg_add function	adds an	argument  with	a  value  that
       contains	embedded nulls to a pattern.

       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 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.
       Type ALL	matches	any argument value type.

       The  ToolTalk  service  treats  the value as an opaque byte string.  To
       pass structured data, the application  and  the	receiving  application
       must  encode and	decode these unique values.  The most common method to
       use is XDR.

       The value argument is the value to be added.  NULL matches any value.

       The len argument	is the length of the value in bytes.

RETURN VALUE
       Upon successful completion, the	tt_pattern_barg_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.
