Hi Chris, Did you compile ptpd with kqueue only? I’ve tried with posix timer, which are implemented in rtems, but it seems that the handler with siginfo_t is not called correctly. I’ve managed to get it working using a workaround but I’ll continue with kqueue, thx!.

Shouldn’t ptimer->inf.sigev_value be used here in order to create a siginfo_t object with the right value? Did anyone have to deal with this while using posix timers? Thanks!

Ptpd uses posix timers and when a timer expires a handler with this signature void(int sig, siginfo_t *info, void *ucontext) is called. Is this on libbsd? If it is I would have expected kqueue being used so I am not sure where this is happening. Chris 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. Diving into the code I’ve found where the handler is called (also where *info is created). This is done in the function _POSIX_signals_Check_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(). My question is: is this handler fully supported? Or maybe I’m missing something else. Thanks in advance, Gabriel —————————————————————————— Deutsches Zentrum für Luft- und Raumfahrt e.V.
