<p class="MsoNormal">From further investigation I’ve found that when a timer expires, _POSIX_Timer_TSR() is called and this uses pthread_kill() to send a signal. Shouldn’t ptimer->inf.sigev_value be used here in order to create a siginfo_t object with the right
value?<o:p></o:p></p>

<p class="MsoNormal">Hello everyone,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Currently I am trying to get running ptpd on rtems (following the Chris’ work, thx btw).<o:p></o:p></p>
<pre><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">Ptpd uses posix timers and when a timer expires a handler with this signature void(int sig, siginfo_t *info, void *ucontext) is called. Unfortunately (*info) doesn’t have the right values, eg. info->si_code should be SI_TIMER but it is SI_USER and also info->si_signo should be the same as sig but it’s not.<o:p></o:p></span></pre>
<pre><span style="font-size:11.0pt;font-family:"Calibri",sans-serif"><o:p> </o:p></span></pre>
<pre><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">Diving into the code I’ve found where the handler is called (also where *info is created). This is done in the function _<i>POSIX_signals_Check</i>_signal() in the file psignalunblockthread.c. It doesn’t seems that info is updated with the values (I guess) should take from object ptimer, which was created by create_timer().<o:p></o:p></span></pre>
<pre><span style="font-size:11.0pt;font-family:"Calibri",sans-serif"><o:p> </o:p></span></pre>
<pre><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">My question is: is this handler fully supported? Or maybe I’m missing something else.<o:p></o:p></span></pre>
