(PECL ev >= 0.2.0)
Fork watchers are called when a
fork()
was detected (usually because whoever signalled
libev
about it by calling
EvLoop::fork()
). The invocation is done before the event loop blocks next and before
EvCheck
watchers are being called, and only in the child after the fork. Note,
that if whoever calling
EvLoop::fork()
calls it in the wrong process, the fork handlers will be invoked, too.
