How to use PCMCIA change notification.
Q: Will I receive notification if my application is using a file that is located on the PCMCIA card and the user closes out the card? A: The PCMCIA library will notify you in this case. It does this by sending MSG_META_REMOVING_DISK to your process object, but only if your application is using a file that is on the card. We recommend that your application quit (without saving to state) when it finds out that this has happened. Warning: Make sure you're not putting your process object on the GCN list that sends out MSG_META_REMOVING_DISK (GCNSLT_REMOVABLE_DISK). Because if you do, then your process object will always receive MSG_META_REMOVING_DISK when a card is removed, not just when you have a file open on the card (in fact, you'll get the message twice).
