Can anyone tell me what type the first argument of FsRtlNotifyFullChangeDirectory in? It is declared as PNOTIFY_SYNC (PVOID actually). Nagar’s book says it is a KMUTEX, but it crashed the system on NT in that function. Through debug I think it should be a FAST_MUTEX. While on W2K, driver verifier reports exception in that function even with FAST_MUTEX.
Anyone knows for sure the type of the PNOTIFY_SYNC on these platforms?
THanks a lot!

You should consider it opaque.You should ask the file system run time to give you a pointer to a NOTIFY_SYNC using
FsRtlNotifyInitializeSync to get a vlaid synch notify object ptr. Subsequently FsRtlNotifyUninitializeSync will clean the object and release any storage associate with it.
