Device Notification

NTDEV
1

I’m interested in Device Notification; been reading up on it and
it appears that its available under W2K+ at the app level. It’s not
clear though, whether removable media notices can be received
(with the current SDK release) through this method and
importantly, whether they are available to a driver.

So, here come the questions for anyone who has had experience
in this area:
0) CAN removable media notices (media is out, media is in)
be received through the SDK mechanism?

  1. Is there an SDK Device Notification analog for drivers?
  2. Is any of this available under NT?
  3. Assuming the answer to 2 is no, is the best way under NT
    to poll the device from the driver through an
    IoBuildDeviceIoControlRequest ()?

Appreciate the help.

No, this is completely different thing.

  1. CAN removable media notices (media is out, media is in)
    be received through the SDK mechanism?

\CdRomMediaChangeEvent or such. Use WinObj to see the exact name.

  1. Is any of this available under NT?

Yes. Media changes are old mechanism, it precedes PnP.
