Read http://clang.llvm.org/docs/Tooling.html

and if you decide libclang is the best choice for you, I strongly
recommend you use the python bindings (rather than writing your indexing
tool in C). Use ipython (with its tab-completion) for discovering the
libclang API.

At the European LLVM conference in April 2012, someone gave a lightning
talk on a C++ class browser he was developing. I don't remember his name
though, and it isn't on the schedule or the slides/videos at
http://llvm.org/devmtg/2012-04-12/

I have written "clang-ctags", a clang-based ctags implementation:

You might consider extending clang-ctags to produce a cscope database,
so you can use Emacs's cscope browser.

Cheers,
Dave.
