First, please fix the email address listed in the From: line.
I tried replying by email, but the email bounced.


Regarding your question, search the archives, and you will find
several options listed. One option is that you could try Elsa/Oink:

Elsa is a C and C++ parser. Oink is a layer on top of Elsa that
simplifies ("lowers") the C++ and puts it into a canonical form so it
is a little easier to deal with. It's open source. It's not perfect,
but it seems fairly solid. We've been using it in our research to
parse and analyze all Debian C/C++ packages, and it works pretty well:
Elsa can parse most, but not all, of those packages.
