> what do you mean what it "doesn't work"When you try to call ffi.C.yourfunction, then you get an error saying that yourfunction can't be resolved.
I don't know if it is because of obscure stdcall naming convention, i.e. "func@XX" unstead of "function". Maybe. I know that people have had binding issues with that in python and java (using respectively ctype and JNA).

I don't think so. The only way I found it to work is by using __declspec(dllexport) + loading explicitely the exe. All access tries through ffi.C failed on my own.
