Hi all,

Is there a way to get DeviceName from PDEVICE_OBJECT?

Thanks in advance,
Fernando.

Yes, it is called an API and it is documented in the DDK.

ObQueryNameString will do the job.

Weren't we talking about documented calls?

I found that IoGetDeviceProperty can return the device name of the PDO, but
that's not exactly what we're talking about.

Sorry if I didn't find it yet but, James, what API were you thinking about
that seemed so obvious?

ObQueryNameString is documented in the IFSKIT.

ObQueryNameString is documented in IFS Kit.

The device objects in PnP stacks usually have no names, except some
autogenerated long string. Usually, device interfaces are used for them.
