请问有没办法防止在关闭文件句柄的时候的windows回写啊。
目前想向一个文件写东西，但是每当用zwclose关闭句柄时，windows都会回写，请各位达人赐教！
谢谢！ |

Probably you can open the file without buffering.
Just curious, why you care about this page flushing after CleanUp? |

谢谢！因为我想改变文件的内容，但是写进去的东西在zwclose后用winhex看，并没有写进去。

After you write something into cache, Cache Manager or File System will decide when to flush the cache. The flushing can be a few seconds later or performed in CleanUp. As long as the file is updated correctly, why you care about when system flushes dirty pages out?

谢谢，问题已经解决，就是缓冲的问题造成的。
