The code is kept, so asking again gives the same answer until <a href="process-free.html"><code>Process.free</code></a>.</p><p>A child ended by a signal (macOS) answers <code>128</code> plus the signal number, as a shell reports it — <code>137</code> after <a href="process-kill.html"><code>Process.kill</code></a>, on both platforms. On Windows the code is the child's DWORD exit code as an <code>int</code>, so a crash such as <code>0xC0000005</code> arrives as a negative number (test for <code>!= 0</code>, not <code>&gt; 0</code>); a code of <code>0xFFFFFFFF</code> is reported as <code>255</code> so that <code>-1</code> always means "still running". A handle that is not one answers <code>255</code>.</p></div>
