Variadic functions

[Null]

How can I use functions from cstdarg header in this situation?

void x(...)
{
// ?
}

int main()
{
x(11,12,13);

}

I know that it should be void x(int number_of_arguments,...) but the above code compiles too so there must be a way to use it.

Thanks for help.

There isn't.

The macros in stdargs start with a given stack reference and allow you to deduce the remainder of the parameters. Without a starting point, you don't know where in the stack to begin.

So why does this code compiles?

[kbw]

If compiles because it's syntactically correct. But you can't access those parameters you passed in.

OK, thanks.
