Do I need to add some special code or something in order to make DLLs, or do normal functions such as int func() work?

well from remembering when i was trying to make dlls in ASM (before my head started to hurt from trying to learn asm) i think you need to make like your own function with a bunch of code and then call that from another program. but if your making windows dlls you need to know about the windows api which i dont because im not that far yet. but im sure they have books about the windows api.

Xception from the GM forum has some great, well-commented examples on his site.

You have to export your functions to be able to import them:
I use this macro:

CODE

#define export extern "C" __declspec( dllexport )

it exports as "C" function(without mangled name) and with cdecl calling convention, use it this way:

CODE

export double myfunc() { return 0;}

Now I know how to do it now. I self-taught myself, whoohoo! (with some help from Xception). :)
