<p style="color: grey"> Python recipe 578899 by <a href="/recipes/users/4190298/">Zack Weinberg</a> (<a href="/recipes/tags/signals/">signals</a>). </p> <p>This is an emulation of the standard (POSIX.1-2008) C library function <a href="http://pubs.opengroup.org/onlinepubs/9699919799/functions/strsignal.html"><code>strsignal()</code></a>, which should be in the <a href="https://docs.python.org/3/library/signal.html"><code>signal</code> module</a>, but isn't.</p> <p>If possible, it uses <a href="https://docs.python.org/3/library/ctypes.html"><code>ctypes</code></a> to call the C library function; otherwise, it tries to build a reverse mapping of the <code>SIG*</code> constants in the signal module; if that doesn't work either, it just produces <code>"signal %d"</code> where <code>%d</code> is the decimal signal number.</p> <p>If invoked as a script, will test all of the strategies and print the results.</p> <p>Tested in 2.7 and 3.4; <em>should</em> work with 2.6 and 3.3 as well.</p>
