NAME
       tt_message_arg_mode -- return the mode of a message argument

SYNOPSIS
       #include <Tt/tt_c.h>
       Tt_mode tt_message_arg_mode(
       Tt_message m,
       int n);

DESCRIPTION
       The tt_message_arg_mode function returns the mode of the nth message argument.

       The  m  argument  is  the  opaque  handle  for  the message involved in this operation.	The n argument is the number of the argument to be
       returned.  The first argument is numbered zero.

RETURN VALUE
       Upon successful completion, the tt_message_arg_mode function returns a value that 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 application can use tt_int_error(3) to extract one of the following Tt_status values from the Tt_mode integer return value:

       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_NUM
		 The integer value passed was invalid (out of range).

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