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 function returns the
  status of the operation as one of the following 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
	  The pointer passed does not point to an object of the correct type
	  for this operation.

  TT_ERR_XDR
	  The XDR procedure failed on the given data, or evaluated to a
	  zero-length expression.
