FsRtlUninitializeOplock uninitializes an opportunistic lock (oplock) pointer.

  POPLOCK Oplock
);

Parameters

Oplock

Opaque opportunistic lock pointer. This pointer must have been initialized by a previous call to FsRtlInitializeOplock.

Return value

None

Remarks

File systems and filter drivers call FsRtlUninitializeOplock to uninitialize an initialized opportunistic lock (oplock) pointer. The uninitialized oplock pointer can be initialized for reuse by calling FsRtlInitializeOplock.

For detailed information about opportunistic locks, see the Microsoft Windows SDK documentation.

Minifilters should call FltUninitializeOplock instead of FsRtlUninitializeOplock.
