Daniel Eklöf	a698fa62e2	reaper: add reaper_del() - pid is no longer watched/monitored after this	2021-01-21 11:55:15 +01:00
Daniel Eklöf	c28bba7a55	reaper: add optional callback ... When calling ‘reaper_add()’, the caller can provide a callback. If non-NULL, the reaper will call the callback to handle the actual reaping. If the callback is NULL, or if it returns false, the reaper reaps the child process.	2021-01-21 11:43:57 +01:00
Daniel Eklöf	f49742ebba	reaper: new module, uses a signalfd to wait() on child processes ... Use a signalfd to listen for SIGCHLD signals. When we receive a SIGCHLD over the signalfd, reap all dead children by looping over all registered child PIDs and call waitpid(WNOHANG) on them.	2020-05-21 20:15:10 +02:00
