Also, Is it better to use libclang for doing this. My complete purpose is to refactor source code to find all functions, their arguments, return statements, all class members and methods. Can I find all this using libclang? I've heard that clang is unstable while libclang is stable. Which one should I use? I am currently using clang's internal API.</blockquote>

My purpose is to overload the << operator for all classes if they don't already have one. The basic goal is to make all classes serializable over some stream (ideally a network stream). Is that possible with clang? If yes, How do I find all the member variables and functions of a class or struct?<div>

I wasn't correctly changing my language from C to C++. I figured that out. It's working now. I wanted to ask you one more thing. I am trying to find all the return statements in the file. I can do that easily but I know want to find out which function does this return statement belong to? Since funcdecl and return statements are de-coupled, I can't find a way to do so. Is there an easy way to do it?</blockquote>

Does getType() not work for you for some reason?<br>
