<em class="">s_watchdog.c</em> is the source of pd-watchdog, which was spawned in <tt class="">sys_startgui()</tt>. pd-watchdog monitors its <tt class="">stdin</tt> for any input, timing out after 5 seconds if nothing was received. In this case it kills <em class="">pd</em> with a <tt class="">SIGHUP</tt>, but normally it will continue looping as long as characters are received from <em class="">pd' at a rate of at least one every 5 seconds. So if <tt class="">pdtk_watchdog</tt> calls </em>pd<em class=""> every 2 seconds and <tt class="">glob_watchdog()</tt> sends a <tt class="">CR</tt> each time through the pipe, everything runs smoothly. </em></p><div class=""><br class=""></div></div><div class="">"pd-watchdog monitors its <tt class="">stdin</tt> for any input” does this also work if i start pd with -stderr >2/dev/null ?</div><div class="">is the fact that i run pd as superuser responsible for pd NOT beeing killed by SIGHUP ?</div></body></html>
