View the official Windows Driver Kit DDI referenceNo description available.
The IoGetOplockKeyContext routine returns a dual oplock key context for a file object.
FileObjectThe file object to query for an oplock key context.
A pointer to an OPLOCK_KEY_CONTEXT structure containing the parent and target oplock keys for FileObject. Otherwise, NULL if FileObject has no oplock keys.
On Windows 8 and later versions of Windows, use IoGetOplockKeyContextEx instead of IoGetOplockKeyContext, as the latter only returns a target oplock key context.
