NAME
     tt_pattern_barg_add - add an argument with	a value	that con-
     tains embedded 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()  func-
     tion  returns the status of the operation as one of the fol-
     lowing Tt_status values:
