Extracting the "real" device name

NTDEV
1

Hi all,

I have a device which has a simbolic name “SymbolicName_0”.

I am writing an application in user mode, and I want to extract the
“real” device name (The none symbolic one).

I know it is possible, because I’have seen programs which does it.
For exmple Osr’s Object viewer shows the relation between the symbolic name and the non-symbolic name.

Thanks
Maurice

QueryDosDevice() will give you the underlying device object name. Why
do you care? What are you trying to do with that information?
