- Subject: Passing arrays(tables) between C++ and Lua and vice versa

I'm creating some functions in c++ and making them available to lua. Some of this functions required to return and/or receive arrays (in lua arrays are implemented with tables right?).
For example, I have a function called setEffects that can receive an indetermined number of ints. How can I do this? I have tried the following code:
int LCamera::setEffects(lua_State *L)
int argument = 1;
luaL_checktype(L, argument, LUA_TNUMBER);
effect = luaL_checkint(L,1);
cout << "effect: " << effect << cout;
} catch (...)
//Do nothing. Only checking number of arguments
cout << "number of arguments: " << argument << endl;
I did this hoping that when there were no more arguments an exception would be thrown and catched in the try-catch block, but it isn't the case. An alternative is to pass as argument an array but how?
The other problem is to return a table. If I have a method that can return several values how can I do it?
