Right. But whether passing happens or not depends on what you mean by
"passing". If the meaning is just that you wrote a function call
expression where the argument x corresponds to the ellipsis, then yes
if (...)
f(x);
you have passed x here, whatever the if condition is. Otherwise you've
passed *nothing*, until (and if) the call is executed.
Genny.
