Shangwu,
I would recommend you to use MmGetSystemRoutineAddress. The platform is not
necessarily constant, so IMHO is better to check whether
IoVolumeDeviceToDosName is present, and to use RtlVolumeDeviceToDosName
otherwise.
Anyway I prefer to use Volume GUID names and translate the path to Win32 in
user mode, as there are volumes without a DOS drive assigned.
Regards,
mK

Asunto: [ntfsd] Is there a simple way to retrieve a DOS path like
C:\dir1\file1 using FltMgr?
I couldn’t find a function in the filter manager to get a DOS drive name. If
I call RtlVolumeDeviceToDosName or IoVolumeDeviceToDosName, I need get the
device object of a volume. Although it seems not a problem to get the device
object based a volume name, the approach involves to check the platform
version in order to call the functions properly. If there is a direct and
simple way to get it, please provide the information.
Thanks in advance,
Shangwu
