DB_CardChanged

This function is used to detect a card change event and restore the database handle accordingly, or if the card has changed, shut down the database. DB_CardChanged must be used to properly access databases that are resident on a card, since turning the unit on and off also generates DOS media changed events. See the example event loop on page 11-444 for more information.
