* is there a way to register for processes state changes from userspace ? @ 2015-07-09 6:39 Ramon Fried 2015-07-09 7:08 ` Nikolay Borisov 0 siblings, 1 reply; 3+ messages in thread From: Ramon Fried @ 2015-07-09 6:39 UTC (permalink / raw) To: kernelnewbies Hi. I'm developing an application that needs to know if any of its clients (different processes) terminated or got killed by a signal. Currently I'm implementing it by looking at the specific PID procfs directory. Is there a better way to achieve that ? Something like netlink notifications for subscribed processes will be great... Thanks. -------------- next part -------------- An HTML attachment was scrubbed...

If your process is abruptly killed then there is no way for the process to tell you that (it's dead after all). Just implement a simple time-out mechanism in the spirit of ping. ^ permalink raw reply [flat|nested] 3+ messages in thread
