I'm sorry but your question is kind of hard to understand so if I seem like I'm rambling it's because I misunderstood you. Normally you don't alter the standard header files that come with you compiler. There are several reasons for this including possibly screwing something up, and ending up with non-standard-standard headers.

No problem, your not the only one here and even some of our best contributors don't speak english as a primary language. The question is did my answer actually have anything to do with your post?

Yes.But i don't know __cdecl.My appraisement :It is calling A func in another out file.
