GNU Global is another tags engine which is more like cscope in being able to support finding both references and definitions. You will be un-surprised to know it also integrates well with Emacs. The main benefit of integrating it into find-src-path is it takes less time to rebuild the database from scratch when you have a lot of build directories under your source tree.
