请问fileobject中RelatedFileObject有什么用处？

谢谢！！！！！！！！！！！

我看到下面一段话，讲的是相对路径和绝对路径的，里面描述了RelatedFileObject的部分作用，应该对你有帮助：

The I/O manager might give either the absolute path or the relative path.
When it supplies the absolute path, then the RelatedFileObject field in the
File Object is NULL, but when it sends the relative path, the
RelatedFileObject field contains the Relative FileName. in
RelatedFileObject->FileName

for e.g: for a file C:\\driver\\filter\\dos
u might get the relative file name as \'dos\' but \'c:\\driver\\filter\' is
contained in RelatedFileObject->FileName. Append this name to the relative
file name to get the absolute path name.

thank you very much

一般的RelatedFileObject->FileName只有在irp_mj_create时才有效。
