IoGetOplockKeyContext function (ntddk.h)
The IoGetOplockKeyContext routine returns a target oplock key context for a file object.
Syntax
POPLOCK_KEY_ECP_CONTEXT IoGetOplockKeyContext(
PFILE_OBJECT FileObject
);
Parameters
FileObject
The file object to query for an oplock key context.
Return value
A pointer to an OPLOCK_KEY_ECP_CONTEXT structure containing the target oplock key for FileObject. Otherwise, NULL if FileObject has no target oplock key.
Remarks
Use the IoGetOplockKeyContext routine only in Windows 7. Because IoGetOplockKeyContextEx returns a dual oplock key context, it should be used in Windows 8 and later versions of Windows.
