IoGetDeviceProperty

when i try to use IoGetDeviceProperty()in my FSF driver i got
a error IoGetDeviceProperty() not found so i included ntddk.h
and i get alot of redefinition errors, can i use
IoGetDeviceProperty ?

This function is not in ntifs.h. If you need to use it, I would suggest
copying just the prototype of it and placing it into your source file.
While not pretty, this is unfortunately necessary because there are some
functions that are only in ntddk.h that are not also in ntifs.h.

Hopefully this will be resolved in the WDK.

Oh, you do understand you won’t be able to use that on a file system
device object, right? File systems do not employ the PDO/FDO
abstraction. It will work on the MEDIA device object, but not the file
system mounted on that media volume.
