Hello, I'm wondering what the proper syntax is for the following: Base.h


extern BOOL (CALLBACK *Functor) (DWORD, DWORD);

code.cpp


BOOL (CALLBACK *Functor) (DWORD, DWORD);

If I were to do a __declspec (dllexport)..where would I put it? I seem to be putting it in the wrong spot? When I try to use the dll it says Functor is undefined thanks

#define DLL_SYMBOL_EXPORT extern "C" __declspec(dllexport)DLL_SYMBOL_EXPORT BOOL (CALLBACK *Functor) MyFunc(DWORD dwWord,DWORD dwWord2) {}

That should work; although I haven't exactly worked with an API callback via DLLs yet; but that's where the __declspec goes. As far as I know you also need the extern "C" because C++ symbol tables turn out to be jumbled.

So then I should just leave my declaration the same then? and export the actual definition?
