如何确定两个Win32 API句柄代表同一对象? [英] How to determine that two Win32 API handles represent the same object?

问题描述

假设我有两个手把:

HANDLE h1;
HANDLE h2;

并且都已接收到某些Windows API函数产生的值-特别是，我对CreateFile()调用产生的句柄感兴趣.如何确定h1和h2引用相同的基础对象(对于CreateFile())是相同的文件，目录或设备?是否有一些API可以确定这一点?

And both have received values resulted from some Windows API function - in particular, I'm interesed in handles resulted from calls to CreateFile(). How do I determine that h1 and h2 reference the same underlying object - in the case of CreateFile() - same file, directory or device? Is there some API to determine that?

推荐答案

您可以使用GetFinalPathNameByHandle并比较两个句柄的文件路径. https://msdn.microsoft. com/en-us/library/windows/desktop/aa364962(v = vs.85).aspx

You could use GetFinalPathNameByHandle and compare the file path of both handles. https://msdn.microsoft.com/en-us/library/windows/desktop/aa364962(v=vs.85).aspx
