If that's what you're expecting, then your message is wrong, because
you say "file never opened" - but you possibly DID open it, and maybe
read something from it. The choice between the two forms should be
based on whether you want to distinguish between errors on opening and
errors on reading, or conflate them as "file unreadable". There are
times and places for each style.
