tt_message_iarg_add(3)
CDE
NAME
  tt_message_iarg_add - add a new argument to a message object

SYNOPSIS
  #include <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:

  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
  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:

  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.
