为Erlang提取C函数签名 [英] Extracting C functions signatures for Erlang

问题描述

我想知道最合适的工具是从源代码中提取c（以及最终c ++）的函数名称，参数及其类型。我想使用一种可以自动完成的工具。

I was wondering what the most suitable tool is for extracting c (and eventually c++) function names, arguments and their types from source code. I would like to use a tool that can be automated as much as possible.

我想提取签名类型，然后让其他用Erlang编写的程序读取输出。我的目标是使用此信息来构造等效于Erlang中的C类型/签名（使用ei）。我希望此过程适用于任何C文件，所以我不能使用任何硬编码的东西。

I want to extract the signature types then have the output read by another program written in Erlang. My goal is to use this information to construct the equivalent of the C types/signatures in Erlang (using ei). I would like this process to work for any C file so I can't use any hardcoded stuff.

我发现很多工具看起来像CLang，CScope和ANTLR等，但我不知道它们中的任何一个是否可行，或者是否有更好的方法。

I have found a lot of tools that look promising like CLang, CScope and ANTLR and so on but I don't know if any of them will work or if there is a better approach out there.

谢谢。

推荐答案

当然还有更好的方法，但是如果您找不到它，则：

Surely there is something better, but if you don't find it:

gcc -aux-info output demo.c
sed '/include/d' output

从跳过标准函数的源代码中提取函数

Extracts functions form source code skipping standard functions
