EvWatcher::keepalive

(PECL ev >= 0.2.0)

EvWatcher::keepaliveConfigures whether to keep the loop from returning

説明

publicboolEvWatcher::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 valueTRUE 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.

パラメータ

value

例1 Register an I/O watcher for some UDP socket but do not keep the event loop from running just because of that watcher.

<?php
$udp_socket 
= ...
$udp_watcher = new EvIo($udp_socketEv::READ, function () {  });
$udp_watcher->keepalive(FALSE);
?>
