How to get a device that a symbolic link points to

NTFSD
1

Hi,

perhaps somebody could give me a hint: I have a drive name (“a:”) in kernel
space, and I want to get the device pointer or the device name that it
points to (“/device/floppy0”). But how?

Thanks in advance
Frank

You should query the symbolink link.
Look into W2K DDK to some routines,
namely ZwOpenSymbolicLinkObject,
ZwQuerySymbolicLinkObject and ZwClose.

NachrichtUse IoGetDeviceObjectPointer to get a pointer to the device. Use ZwOpenSymbolicLinkObject/ZwQuerySymbolicLinkObject to find out where a symbolic link points.
