Actually, this is not really clear.  The definition of a function is the
thing that has the actual code, like

int foo(int x) {
  return x;
}

What you are referring to is the prototype, ie

int foo(int);

What you want to say is that function prototypes should also have
parameter names.

The second --- is not needed.
