I have tried blocking signals for other threads but I have little luck so far. It seems that there is no way to block signals for all new threads that will be created, or are they blocked when created. From what I can tell, they are not. But my main problem is that when I block signals for the main thread, other threads don't handle the signal. In the main function the first thing I do is setting up a signal handler. After that I create a new thread that should handle the signals and check the flag (I will try if I can use pause or sigwait for that). After the thread is created, I use the following code block the relevant signals for this thread: struct hurd_sigstate *ss; sigset_t mask; sigemptyset (&mask); sigaddset (&mask, SIGTERM); sigaddset (&mask, SIGINT); sigaddset (&mask, SIGHUP); ss = _hurd_self_sigstate (); ss->blocked = mask; This code works perfectly. The main thread does not handle the signals anymore. But what confuses me is that signals aren't handled anymore (at all). This was what I tried to unblock the newly created thread (which AFAIK is not blocked), this code is run inside that thread: struct hurd_sigstate *ss; ss = _hurd_self_sigstate (); sigemptyset (&ss->blocked); This did do what I hoped it would do (although I did not really expect it would). I just want to make clear the thread does not block signals. Can someone please tell me what I did wrong or what would be a better way to do this?
