Get all the functions' names from c/cpp files

Question

For example, there is a C file a.c, there are three functions in this file: funA(), funB() and funC().

I want to get all the function names from this file.

Additionally, I also want to get the start line number and end line number of each function.

Is there any solution?

Can I use clang to implement it?

Answer 1

You can compile the file and use nm http://en.wikipedia.org/wiki/Nm_(Unix) on the generated binary. You can then just parse the output of nm to get the function names.

If you want to get line numbers, you can use the function names to parse the source file for line numbers.

All the this can be accomplished with a short perl script that makes system calls to gcc and nm.

This is assuming you are using a *nix system of course...
