Checking ferror is good enough as long as you rely only on fwrite, and
not say, *printf. Some *printf failures are specified as not detectable
via ferror (but of course, the standard does not say that outright).
But that's why we have xfprintf - for those cases where you can have
failure without having ferror() set.
