A file system or filter driver calls FsRtlCurrentBatchOplock to determine whether there are any batch or filter opportunistic locks (oplocks) on a file.

Syntax

BOOLEAN FsRtlCurrentBatchOplock(
  [in] POPLOCK Oplock
);

Parameters

[in] Oplock

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

Return value

FsRtlCurrentBatchOplock returns TRUE if there are current outstanding batch or filter opportunistic locks; FALSE otherwise.

Remarks

FsRtlCurrentBatchOplock returns FALSE if no batch or filter opportunistic locks are currently held.

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

Minifilters should call FltCurrentBatchOplock instead of FsRtlCurrentBatchOplock.
