FltCurrentOplock function (fltkernel.h)

A minifilter driver calls the FltCurrentOplock routine to determine whether there are any opportunistic locks (oplocks) on a file.

Syntax

BOOLEAN FLTAPI FltCurrentOplock(
  [in] POPLOCK Oplock
);

[in] Oplock

An opaque oplock pointer for the file. This pointer must have been initialized by a previous call to FltInitializeOplock.

FltCurrentOplock returns TRUE if there are oplocks that are currently being held. Otherwise, it returns FALSE.

FltCurrentOplock returns FALSE if no opportunistic locks are currently held.

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