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

Returns the previous state.
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 );
?>
