Why is void f(…) not allowed in C?

Question

Why doesn\'t C allow a function with variable length argument list such as:

void f(...)
{
    // do something...
}

Answer 1

Playing around with it, made this nice implementation that I think some people might want to consider.

template
void print(T first, ...)
{
    va_list vl;
    va_start(vl, first);
    T temp = first;
    do
    {
        cout << temp << endl;
    }
    while (temp = va_arg(vl, T));
    va_end(vl);
}

It ensures you have one variable minimum, but allows you to put them all in a loop in a clean way.
