Since C++ can't access BlitzMax lists, here is my function to iterate through all entities in the world. What would the C++ end of this look like?Function dll_ForEachEntityDo(func:Byte Ptr) "win32" Local entity:TEntity Local callback:Int(hentity:Int) "win32" callback=func For entity=EachIn currentworld().entities If callback(entity.handle)=0 Return Next EndFunction |

I'm not sure what you want your callback to do, or how you're loading the DLL (load-time or run-time), but since your blitzmax code is calling the callback using the stdcall convention you need to declare your C++ function with __stdcall or whatever your compiler uses. |
