I've made a program which uses the WinAPI for some actions, the only thing I have to do is replace/rewrite that code with code that should work on linux. But I don't know where to start. Can someone help me?
Thanks, but that is a whole toolkit which is portable across some OSes.
Anyway, I found out about POSIX, which is compliant on most Linux distros and some other OSes, like Solaris and OS X, and some are mostly compliant like BSD. I think this will do the trick for me ;).
