FsRtlProcessFileLock function (ntifs.h)
The FsRtlProcessFileLock routine processes and completes an IRP for a file lock operation.
Syntax
NTSTATUS FsRtlProcessFileLock(
[in] PFILE_LOCK FileLock,
[in] PIRP Irp,
[in, optional] PVOID Context
);
Parameters
[in] FileLock
Pointer to the FILE_LOCK structure for the file. This structure must have been initialized by a previous call to FsRtlAllocateFileLock or FsRtlInitializeFileLock.
[in] Irp
Pointer to the IRP. Must be an IRP for a file-lock operation.
[in, optional] Context
Optional context pointer to be used when completing IRPs.
Return value
FsRtlProcessFileLock returns STATUS_SUCCESS on success; otherwise it returns an appropriate error status code.
Remarks
FsRtlProcessFileLock performs the specified lock operation on behalf of the process associated with thread that originally requested the operation.
On Microsoft Windows XP and later, this is the process to which the thread is currently attached.
On Microsoft Windows 2000 and earlier, it is the process that created the thread.
Callers of FsRtlProcessFileLock relinquish control of the input IRP.
Minifilters must call FltProcessFileLock instead of FsRtlProcessFileLock.
