# The EvChild class

(PECL ev >= 0.2.0)

## Introdução

EvChild watchers trigger when the process receives a `SIGCHLD` in response to some child status changes (most typically when a child dies or exits). It is permissible to install an `EvChild` watcher after the child has been forked(which implies it might have already exited), as long as the event loop isn't entered(or is continued from a watcher), i.e. forking and then immediately registering a watcher for the child is fine, but forking and registering a watcher a few event loop iterations later or in the next callback invocation is not.

It is allowed to register EvChild watchers in the default loop only.
