Using a function with a variable number of arguments [duplicate]

Question

Consider the following code:

#include <iostream>

int var_arg_func(...)
{
    std::cout << "Func called!";
}

int main()
{
    var_arg_func(0, 1, 2);
}

As you can see here I can pass a variable number of arguments to the function var_arg_func.

But my question is how can I access those arguments from the function itself? (I'm using C++20)
