Unregistering from the ToolTalk Service

When you want to stop interacting with the ToolTalk service and other ToolTalk session participants, you must unregister your process before your application exits.

    /*
     * Before leaving, allow ToolTalk to clean up.
     */
    tt_close();

    exit(0);
}

tt_close returns Tt_status and closes the current default procid.
