Description
final public static Ev::embeddableBackends ( ) : int
Returns the set of backends that are embeddable in other event loops.
Parameters

Return Values
Returns a bit mask which can containing backend flags combined using bitwise OR operator.
Examples
Example #1 Embedding loop created with kqueue backend into the default loop
<?php/** Check if kqueue is available but not recommended and create a kqueue backend* for use with sockets (which usually work with any kqueue implementation).* Store the kqueue/socket-only event loop in loop_socket. (One might optionally* use EVFLAG_NOENV, too)** Example borrowed from* http://pod.tst.eu/http://cvs.schmorp.de/libev/ev.pod#Examples_CONTENT-9*/$loop = EvLoop::defaultLoop();$socket_loop = NULL;$embed = NULL;if (Ev::supportedBackends() & ~Ev::recommendedBackends() & Ev::BACKEND_KQUEUE) { if (($socket_loop = new EvLoop(Ev::BACKEND_KQUEUE))) { $embed = new EvEmbed($loop); }}if (!$socket_loop) { $socket_loop = $loop;}// Now use $socket_loop for all sockets, and $loop for anything else?>
