how to do waitpid() using a multi-threaded server?


i'm running a multi-threaded server, which forks it's children
but my problem is, if the child exits it's a zombie process

in the server i'm using accept to wait for connections
so i don't realy have the time to do waitpid()

how can i terminate my childs without having a problem of missing a connection from a client?
is there a way to do this event-based
if a child exits, i do waitpid

you can use wait3 or wait4 and pass the WNOHANG flag to them or better
when a child process ends Linux sends the parent a SIGCHILD signal
so all you have to do is handle SIGCHILD
