Converting NT path to DOS path with a UNICODE_STRING

edited January 2020 in NTFSD

Hi, i'm making a minifilter to monitor when images are mapped in a certain path. In order to do that i'm using the PloadImageNotifyRoutine callback registered by PsSetLoadImageNotifyRoutine.
The problem i have is that when the callback is called i have an UNICODE_STRING with a NT path like \Device\HarddiskVolume6. I would like to get the corresponding letter to this device in order to compare it with the path i want to monitor. How can i convert it (or convert the DOS path to an NT one) in order to compare them?
