Expand description
A structure for the spawn API.
This may be used to integrate auto spawned daemons into your application. For more information
see Context::connect()
. When spawning a new child process the waitpid()
is used on the
child’s PID. The spawn routine will not block or ignore SIGCHLD signals, since this cannot be
done in a thread compatible way. You might have to do this in prefork/postfork.
Fields§
§prefork: Option<extern "C" fn()>
Is called just before the fork in the parent process.
postfork: Option<extern "C" fn()>
Is called immediately after the fork in the parent process.
atfork: Option<extern "C" fn()>
Is called immediately after the fork in the child process.
It is not safe to close all file descriptors in this function unconditionally, since a UNIX socket (created using socketpair()) is passed to the new process.
