Using cccc with pure C?

Has anyone used cccc with pure C code?

I tried it and it seems to handle all the files as one module, which 开发者_如何学JAVAmeans that most of the counters are useless (e.g. there is no fan-in or fan-out since there is just one module).

Can I somehow tell it to do this comparison on a file-by-file basis (i.e. each file is one module)?

Seems a little bit outdated. I usually use sloccount with good results.
