EvWatcher::keepalive — Configures whether to keep the loop from returning


Описание

public bool EvWatcher::keepalive ([ bool $value ] )

Configures whether to keep the loop from returning. With keepalive value set to FALSE the watcher won't keep Ev::run() / EvLoop::run() from returning even though the watcher is active.

Watchers have keepalive value TRUE by default.

Clearing keepalive status is useful when returning from Ev::run() / EvLoop::run() just because of the watcher is undesirable. It could be a long running UDP socket watcher or so.
