Compile a DLL in C/C++, then call it from another program

Question

I want to make a simple, simple DLL which exports one or two functions, then try to call it from another program... Everywhere I\'ve looked so far, is for complicated matter

Answer 1

The thing to watch out for when writing C++ dlls is name mangling. If you want interoperability between C and C++, you'd be better off by exporting non-mangled C-style functions from within the dll.

You have two options to use a dll

• Either use a lib file to link the symbols -- compile time dynamic linking
• Use LoadLibrary() or some suitable function to load the library, retrieve a function pointer (GetProcAddress) and call it -- runtime dynamic linking

Exporting classes will not work if you follow the second method though.
