include c file in c++ workspace (LNK2001 problem)

Hi,

I am having a dialog based MFC project and had to include a lot of c files from an older project. In one of the c files there is the only function which is supposed to be accessable from a .cpp file (the one implementing the dialog class). But I always get unresolved external symbol..
Can you tell me how do I have to include non-MFC functions in order to work?
I'm talking about the normal way to do that (suppose I have the file: a.c containing the function " test(char*, char*)" to be exported to file bDlg.cpp). How do I have to declare "test", etc.
Then I'll check if I did it right..

Thanks in advance!

Code:

---

#ifdef __cplusplus
extern "C" int test(char*, char*);
#else
int test(char*, char*);
#endif

I guess you might use extern "C" directive for C-style linkage

That was it! Thanks guys! :)
