如何获取重定向路径的实际路径？ [英] How to get Actual path of redirected path?

问题描述

由于文件重定向，在64位上运行的32位进程将获得到重定向路径的广义路径。例如，如果进程正在从 \Windows \SysWOW64 运行，则会调用 GetCurrentDirectory code> Windows\System32 。

A 32-bit process running on 64-bit would get generalized path to a redirected path, due to file-redirection. A call to GetCurrentDirectory, for example, if process is running from \Windows\SysWOW64 would get result: Windows\System32.

但是，很有可能确定32位进程是否正在64位主机上运行。我正在寻找一个解决方案给我正确/实际的路径。像ResolveWOWPathToActual路径，这将给 \Windows \SysWOW64 路径 \Windows \System32 。

Though, it is very much possible to determine if 32-bit process is running on 64-bit host machine. I am looking for a solution to give me correct/actual path. Something like ResolveWOWPathToActual path, that would give \Windows\SysWOW64 for a path \Windows\System32.

编辑：

WCHAR szCurFolder[MAX_PATH];

PVOID dummy;
Wow64DisableWow64FsRedirection(&dummy);

GetCurrentDirectoryW(MAX_PATH, szCurFolder);

printf("Current Dir: %S\n", szCurFolder);

推荐答案

API函数 GetFinalPathNameByHandle 可能满足您的需求。您将必须打开文件或目录来获取它的句柄。将该句柄传递到 GetFinalPathNameByHandle ，它将为您提供文件的真实路径。没有必要禁用文件系统重定向程序。

The API function GetFinalPathNameByHandle might serve your needs. You will have to open the file or directory to obtain a handle to it. Pass that handle to GetFinalPathNameByHandle and it will give you the true path of the file. There is no need to disable the file system redirector.

我认为唯一可能的缺点是，这需要你提供句柄而不是路径。

I suppose the only possible downside is that this does require you to supply a handle rather than a path.
