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::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.
