is there any tools that can extract all variables(both public and static) from a set of C files?

Question

Hi Guys,

I'm wondering if there is any tools that can extract all variables(both public and static) from a set of C files and then export all referenced variables to a text file.

Thanks in advance.

Answer 1

Doxygen does this pretty well (here are some examples). ctags does this too but I haven't really played with it much aside from using it in vim. I'm sure the tags file can be made parseable.

Answer 2

You can try CScope

Answer 3

The Unix nm(1) on the binary may be helpful. And I used cxref about 15 years ago.

Answer 4

Not sure this will help you but that would be easy to do with Cil from http://www.eecs.berkeley.edu/~necula/cil/index.html the problem is you will need to learn OCaml to use it. (Some people might consider that a feature.)
