Parameters

Opaque oplock pointer. This pointer must have been initialized by a previous call to FltInitializeOplock.

Return value

None

Minifilter drivers call FltUninitializeOplock to uninitialize an initialized opportunistic lock (oplock) pointer. The uninitialized oplock pointer can be initialized for reuse by calling FltInitializeOplock.
