   void * ud = lua_newuserdata(L, /* What to come here? */);
   // Probably a metatable to be assigned to 'ud' here

   return 1; // The userdata, being wxWidget actually
}

static luaL_Reg funs [] =
{ { "GetConsoleWindowsAsWxWindow", GetConsoleWindowsAsWxWindow },
   { NULL, NULL }
};

__declspec(dllexport) int luaopen_MyLib(lua_State * L)
{
   lua_newtable(L);
     luaL_setfuncs(L, funs, 0);
   lua_setglobal(L, "MyLib");

   return 0;
}
