PATH_NOT_FOUND和NAME_NOT_FOUND有什么区别 [英] What's the difference between PATH_NOT_FOUND and NAME_NOT_FOUND

问题描述

在Win32层中，我们经常遇见 ERROR_PATH_NOT_FOUND ， ERROR_NAME_NOT_FOUND 。

何时 WinAPI（例如CreateFileW，RemoveDirectoryW）返回这些值？
有什么区别？

如果我写一个文件系统驱动，我什么时候设置 STATUS_OBJECT_PATH_NOT_FOUND 或 STATUS_OBJECT_NAME_NOT_FOUND ？

您如何确定？

我很困惑。
有没有人可以解释清楚？

或者有没有文件解释这个？我找不到他们。 ERROR_NAME_NOT_FOUND 不是标准的Win32 API错误代码。与文件相关的文件名API返回的典型错误是 ERROR_FILE_NOT_FOUND 和 ERROR_PATH_NOT_FOUND 。找出返回错误代码的最佳方法是使用WDK示例作为指导。例如，cdfs示例的 create.c 源代码文件。如果无法找到目录，它将返回 STATUS_OBJECT_PATH_NOT_FOUND STATUS_OBJECT_NAME_NOT_FOUND

In Win32 layer, we often meet 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.

解决方案

ERROR_NAME_NOT_FOUND is not a standard Win32 API error code. Typical errors returned by file related APIs that take a file name are ERROR_FILE_NOT_FOUND and ERROR_PATH_NOT_FOUND. The best way to figure out what error code to return is use a WDK sample as a guide. The cdfs sample's create.c source code file for example. It returns STATUS_OBJECT_PATH_NOT_FOUND if it cannot locate a directory, STATUS_OBJECT_NAME_NOT_FOUND if it cannot locate a file.
