I've been looking for a way to send the data which my device driver makes as a result to user mode application. For instance, I send a specific process id in user mode to my device driver and my device driver sends it back to in user mode after some calculation or something. My device driver operates with IOCTL. So once I thought there was a space/buffer as structure in PIRP structure for sending to user mode application. Following a lot of searching about this, I've got no useful reference, information for use. Does anybody give me any clues on this matter? I would appreciate even if it's a little of help. Thanks in advance.

I have been looking that site over now but too broad to find a solution. Thanks anyway!

The DDK documentation is the best place to look.
