更改 dll 的接口意味着更改 dll 和调用代码的交互方式。这可能意味着更改 dll 导出函数的签名，或者完全更改为一组不同的函数，或者可能意味着从调用代码传递不同的数据。 DLL 的接口通常是其导出和导入的所有项（函数和数据），或者换句话说，是您在使用 DLL 时可以访问的部分。
通常您会希望更改 dll 的行为而不更改其接口。这是因为经常更改接口会破坏使用它的代码。
想象一下我的 dll 导出函数
foo：更改接口可能意味着将
foo的签名更改为现在，之前使用 foo 的所有代码都必须重写以使用新签名，这可能是一件坏事。
Changing a dll's interface would mean to change how the dll and the calling code interacts. This could mean changing the signatures of the dll's exporting functions, or changing to a different set of functions entirely, or it could mean passing different data from the calling code. A dll's interface is generally all it's exported and imported items (both functions and data), or in other words, the parts of the dll that you have access to when you use it.
Often you will want to change the behaviour of your dll without changing its interface. This is because changing the interface often will break code that uses it.
Imagine my dll exporting function
foo:Changing the interface could mean changing
foo's signature intoNow, all the code that used foo previously has to be rewritten to use the new signature, which could be a bad thing.
