How to get device object name

NTDEV
1

Hi,

I have created a volume filter device object and attached the same to the system device’s stack using IoAttachDeviceToDeviceStack. can I get a volume device’s name to which my filter device has been attached (such as /Device/HarddiskVolume1 or something)?

Thanks & Regards…

Why do you need the name? For debugging purposes or for something else?

For debugging purpose - want to track from which volume the request is coming. Could you suggest something? Thanks!

Hi Doron,

Thanks for reply!
Its a function supported in IFS kit rather I’ll require ntifs.h to use this function in DDK. I don’t have IFS kit (can’t afford) / ntifs.h. Is there any workaround function this one? Thanks!

The IFS Kit is no more. The good news is that it’s contents have been
rolled in to the WDK, free of charge. I’m not sure exactly when this
occurred, but it is definitely in the Vista 6000 WDK, which is the
official one in any case.

Good luck,

mm
