<p>This works around deficiencies of the gethostname call, namely that it does not return an error of the supplied buffer is too small and that it may not include a NUL byte at the end of the buffer if the buffer was too small and the returned name was truncated.</p>
<p>This should not happen (often) in practise since glibc already has a similar workaround in place, but may happen eg on a Mac if they indeed use a non glibc C library.</p>
