Re: [ntfsd] RE: How to get the volume lable from the pointer to the volume?

Hi:
I tried to invoke RtlVolumeDeviceToDosName() but an error " error C4013: ‘RtlVolumeDeviceToDosName’ undefined; assuming extern returning int" was reported.I checked my my ntddk.h and found the declaration of RtlVolumeDeviceToDosName().
What should I do then?
Thanks!

Jim
