FsRtlFreeFileLock function (ntifs.h)
The FsRtlFreeFileLock routine uninitializes and frees a file lock structure.
Syntax
void FsRtlFreeFileLock(
[in] PFILE_LOCK FileLock
);
Parameters
[in] FileLock
Pointer to the FILE_LOCK structure. This structure must have been allocated by a previous call to FsRtlAllocateFileLock.
Return value
None
Remarks
FsRtlFreeFileLock should be used only for file locks that were allocated and initialized by FsRtlAllocateFileLock.
It is a programming error to call FsRtlFreeFileLock for a FILE_LOCK structure that has already been uninitialized by a call to FsRtlUninitializeFileLock.
Minifilters must call FltFreeFileLock instead of FsRtlFreeFileLock.
