(PECL ev >= 0.2.0)

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

Description

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.

Parameters

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

Return Values

Returns the previous state.

Examples

Example #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_socket, Ev::READ, function () { /* ... */ });
$udp_watcher->keepalive(FALSE);
?>
