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

["Zé Pedro" <zarroba@...>]

Hi,
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;
    try
    {
        lua_Number effect;
        while (true)
        {
            luaL_checktype(L, argument, LUA_TNUMBER);
            effect = luaL_checkint(L,1);
            cout << "effect: " << effect << cout;
            argument++;
        }
    } catch (...)
    {
        //Do nothing. Only checking number of arguments
        cout << "number of arguments: " << argument << endl;
    }

    return 0;
}
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?

thanks,
