Detailed Description

A structure for the spawn api.

This may be used to integrate auto spawned daemons into your application. For more information see pa_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.

Field Documentation

void(* pa_spawn_api::atfork)(void)

Is called immediately after the fork in the child process.

May be NULL. 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.

void(* pa_spawn_api::postfork)(void)

Is called immediately after the fork in the parent process.

May be NULL.

void(* pa_spawn_api::prefork)(void)

Is called just before the fork in the parent process.

May be NULL.
