PATH_NOT_FOUND 和 NAME_NOT_FOUND 有什么区别

Question

在Win32层，我们经常会遇到ERROR_PATH_NOT_FOUND，ERROR_NAME_NOT_FOUND.

When does WinAPI(eg CreateFileW, RemoveDirectoryW) return these values? And What's the difference?

If I write a file system driver, when do I set STATUS_OBJECT_PATH_NOT_FOUND or STATUS_OBJECT_NAME_NOT_FOUND?

How do you determine?

I'm so confused. Is there anyone who can explain clearly?
Or are there any documents explain this? I couldn't find them.

Thanks in advance.

ERROR_NAME_NOT_FOUND不是标准 Win32 API 错误代码。采用文件名的文件相关 API 返回的典型错误是ERROR_FILE_NOT_FOUND和ERROR_PATH_NOT_FOUND。确定要返回什么错误代码的最佳方法是使用 WDK 示例作为指导。create.c例如，cdfs 示例的源代码文件。STATUS_OBJECT_PATH_NOT_FOUND如果找不到目录或STATUS_OBJECT_NAME_NOT_FOUND文件，则返回。
