Yes, just don't change the re-trap the signal in the handler, leave it as is. testsuite/latency.c illustrates this, we trap SIGDEBUG to SIG_DFL only when the -b option was given (stop_upon_switch), to make sure the default action will be taken when we resend it for exiting. -- Philippe. _______________________________________________ Xenomai mailing list Xenomai@xenomai.org https://xenomai.org/mailman/listinfo/xenomai
