How to use Symbolic Link Name of IoRegisterDeviceInterface() in the Applications

Hi,
I written a win2k plug n play driver for pcmcia 16 bit PC card and
this driver successfully recognized the card. In driver, in
IoCreateDevice funtion I given Device name as NULL and Device type as
FILE_DEVICE_UNKNOWN. I used IoRegisterDeviceInterface() to pass the
parameter class GUID as mentioned in INF file, and Address of symbolic
Link Name.
To get the handle of this device,I want to use this symbolic Link
Name in CreateFile() in the Application.
My doubt is how I can access the symbolic Link name in the
application,because Iam having symbolic Link name in the driver.
please guide me in getting the handle of the device in my application.
Shall I use IoCreateSymbolicLink()?
Is there any other method to get the handle?
please reply the procedure.

bye,
Mahender.

Use the 'SetupDi*' apis (in the SDK) to enumerate your device interfaces
and obtain the symbolic link names you need.

also, you should use a separate guid from the class GUID in the INF. use a
new guid (see uuidgen.exe to create one) instead.
