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.

Re: DOS path for "\Device\HarddiskVolume2" ?

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. //Daniel <xxxxx@yahoo.com> wrote in message news:94034@ntfsd... > QueryDosDevice() working ok, is just reverse order: > > wchar_t awcBuf[ 513 ]; > > QueryDosDeviceW(L"C:", awcBuf, 513); // awcBuf...output as > L"\Device\HarddiskVolume1" > > Thank you. > >
