tt_pattern_barg_add(3)
CDE
NAME
  tt_pattern_barg_add - add an argument with a value that contains 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 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 service cannot
      restart it.

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