How are you compiling this? C++ compilers perform name mangling
which is incompatible with WinAPI calling conventions.

I guess you can override the objects, but then question becomes
why would you do this? It's an object and you can't really
create it on your own. You'd have to load it in DLLMain and then
leave it running the entire lifetime of the DLL.
