CcUninitializeCacheMap function (ntifs.h)
The CcUninitializeCacheMap routine stops the caching of a cached file.
Syntax
BOOLEAN CcUninitializeCacheMap(
[in] PFILE_OBJECT FileObject,
[in, optional] PLARGE_INTEGER TruncateSize,
PCACHE_UNINITIALIZE_EVENT UninitializeEvent
);
Parameters
[in] FileObject
Pointer to a file object for the cached file.
[in, optional] TruncateSize
If specified, the file was truncated to the specified size, and the cache should be purged accordingly.
UninitializeEvent
If specified, the provided event is set to the signaled state when the cached file data has been flushed to disk.
Return value
CcUninitializeCacheMap returns TRUE if caching was stopped successfully, FALSE otherwise.
Remarks
All file systems that support file caching must call CcUninitializeCacheMap when closing a file, whether the file is cached or not. Even if the file was created with caching disabled, the file system still must call CcUninitializeCacheMap.
To cache a file, use CcInitializeCacheMap.
