<p>Manpage says otherwise:</p>
<blockquote>
<p>If the time limit expires, <code>select()</code> returns 0</p>
</blockquote>
<p>And some tutorial says:</p>
<blockquote>
<p>On success, <code>select()</code> and <code>pselect()</code> return the number of file descriptors contained in the three returned descriptor sets (that is, the total number of bits that are set in <code>readfds</code>, <code>writefds</code>, <code>exceptfds</code>) which <em>may be zero if the timeout expires before anything interesting happens</em>.</p>
</blockquote>
<p>I don't see how <code>select</code> should ever return <code>0</code> for a writable <code>fd</code></p>
