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.
