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:

       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.
