DOS path for "\Device\HarddiskVolume2" ?

is there any way to find the DOS pathname for "\Device\HarddiskVolume2"
like "C:".

The path is initially from ZwQueryInformationProcess(), IoVolumeDeviceToDosName()
cannot be used in this case.

Any suggestion, will be appreciated.

QueryDosDevice() working ok, is just reverse order:

wchar_t awcBuf[513];

QueryDosDeviceW(L"C:“, awcBuf, 513); // awcBuf…output as L”\Device\HarddiskVolume1"

Thank you.

You should realize there is a one to many mapping between device paths and
symbolic links names. That’s why it cannot work in reverse order. You can
pass in NULL to get a list of all DOS device names or otherwise pass in all
leters of the alphabet one by one. (Italians be aware that the British
alphabet contains 5 letters more). BTW there is a discussion on this topic a
few threads below in case you missed it.
