如何找出DLL档案的API功能? [英] How to find out API functions of DLL files?

问题描述

是否可以从 DLL文件中获取所有 API(导出)功能?

Is there a way to get all the API (Export) functions from a DLL file?

我知道 Depend s和 PE Explorer 之类的程序可以做到这一点，但是它们都不检索参数列表.

I know that programs such as Depends and PE Explorer can do that but none of them retrieve the argument list.

推荐答案

除非导出的函数是带有munging的COM DLL或C ++之类的信息，否则根本就不会提供信息来提供参数.通常可以找到参数的总大小，并且很有可能除以4会得到接近正确数字的值，但除此之外，这还取决于手工操作，请阅读汇编代码以弄清楚参数的方式使用.

Unless the exported functions are something like a COM DLL or C++ with munging, the information simply isn't there to provide the arguments. It's normally possible to find the total size of the arguments, and there's a pretty decent chance that dividing by 4 will give something close to the right number, but beyond that it's down to manual labor, reading the assembly code to figure out how arguments are used.

如果它是COM DLL，则可能包括一个类型库，该类型库告诉 all 有关DLL的内容以及如何使用它.在这种情况下，通常只有非常个导出的函数需要查看-您必须使用COM才能获得真正的功能.

If it's a COM DLL, it may include a type library that tells all about the contents of the DLL and how to use it. In this case, there will typically be only a very few exported functions to look at though -- you'll have to use COM to get at the real functionality.

如果它们是C ++名称，则将取决于用于创建DLL的编译器/工具集.例如，如果它是使用VC ++创建的，则可以使用 UnDecorateSymbolName()来获取全名和参数.

If they're munged C++ names, then it'll depend on the compiler/toolset used to create the DLL. For example, if it was created with VC++, you can use UnDecorateSymbolName() to get the full name and arguments.
