    Talking fn(...)

    What is this ... thing and how to you access it in the function body?

    Code:
    void fn(...)
    {
    
    
    }

    It's for variable argument lists. If you're using C++, then try to avoid ever using it. If you're using C, then try to avoid ever using it, but if you have to then look up VA_ARGS.
    Correct is better than fast. Simple is better than complex. Clear is better than cute. Safe is better than insecure.
