Hi,
In my filter driver i have created a named device object and i want to Implement custome IOCTLs to be used by the Filter driver’s Client application.
The question is how to recieve and differentiate from Target device the requests like CreateFile /Close File and Custom IOCTLs in the filter driver so that they can be handled appropriately.
Any Help is appreciated…

Put some kind of signature in the Device extension of each device. The
signature must be at the same byte offset in each extension (first in the
extension is probably the safest).
