Is EINTR considered an error for this purpose? If not, what exactly
is considered an error? I don't see this clearly documented, so it
could be something we cannot rely on. In fact, I don't even see in
portable documentation that it will return EOF upon errors, I only see
that the error indication for the stream shall be set and errno shall
be set.
In short, it sounds like calling fwrite in a loop will only work by
sheer luck.
