ObUnRegisterCallbacks function (wdm.h)
The ObUnRegisterCallbacks routine unregisters a set of callback routines that were registered with the ObRegisterCallbacks routine.
void ObUnRegisterCallbacks( [in] PVOID RegistrationHandle );
A value that identifies the set of callback routines to unregister. The ObRegisterCallbacks routine provides this value when it originally registered the callback routines.
A driver that calls the ObRegisterCallbacks routine must call the ObUnRegisterCallbacks routine before the driver is unloaded.
Do not call ObRegisterCallbacks more than once. This is a "double free" and results in Bug Check 0x7E: SYSTEM_THREAD_EXCEPTION_NOT_HANDLED.
