NAME
  tt_message_iarg_add - add a new argument to a message object

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

DESCRIPTION
  The tt_message_iarg_add function adds a new argument to a message object
  and sets the value to a given integer.

  Add all arguments before the message is sent.	 To change existing argument
  values, the application must use only modes TT_OUT or TT_INOUT.

  Adding arguments when replying to a message produces undefined results.

  The m argument is the opaque handle for the message involved in this
  operation.  The n argument specifies who (sender, handler, observers)
  writes and reads a message argument.	The following modes are defined: The
  argument is written by the sender and read by the handler and any
  observers.
  The argument is written by the handler and read by the sender and any reply
  observers.
  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
  value argument is the value to be added.

RETURN VALUE
  Upon successful completion, the tt_message_iarg_add function returns the
  status of the operation as one of the following Tt_status values: The
  operation completed successfully.
  The specified Tt_mode is invalid.
  The ttsession1 process is not running and the ToolTalk service cannot
  restart it.
  The pointer passed does not point to an object of the correct type for this
  operation.
