AnyEvent::Impl::EV(3pm) User Contributed Perl Documentation AnyEvent::Impl::EV(3pm)NAME
AnyEvent::Impl::EV - AnyEvent adaptor for EV
SYNOPSIS
use AnyEvent;
use EV;
# this module gets loaded automatically as required
DESCRIPTION
This module provides transparent support for AnyEvent. You don't have to do anything to make EV work with AnyEvent except by loading EV
before creating the first AnyEvent watcher.
EV is the fastest event library for perl, and best supported by AnyEvent. Most functions from the AE API are implemented as direct aliases
to EV functions, so using EV via AE is as fast as using EV directly.
SEE ALSO
AnyEvent, EV.

Coro::Socket - non-blocking socket-I/O
SYNOPSIS
use Coro::Socket;
# listen on an ipv4 socket
my $socket = new Coro::Socket PeerHost => "localhost",
PeerPort => 'finger';
# listen on any other type of socket
my $socket = Coro::Socket->new_from_fh
(IO::Socket::UNIX->new
Local => "/tmp/socket",
Type => SOCK_STREAM,
);
DESCRIPTION
This module is an AnyEvent user, you need to make sure that you use and run a supported event loop.
This module implements socket-handles in a coroutine-compatible way, that is, other coroutines can run while reads or writes block on the
handle. See Coro::Handle, especially the note about prefering method calls.
IPV6 WARNING
This module was written to imitate the IO::Socket::INET API, and derive from it. Since IO::Socket::INET does not support IPv6, this module
does neither.
Therefore it is not recommended to use Coro::Socket in new code. Instead, use AnyEvent::Socket and Coro::Handle, e.g.:
use Coro;
use Coro::Handle;
use AnyEvent::Socket;
# use tcp_connect from AnyEvent::Socket
# and call Coro::Handle::unblock on it.
tcp_connect "www.google.com", 80, Coro::rouse_cb;
my $fh = unblock +(Coro::rouse_wait)[0];
# now we have a perfectly thread-safe socket handle in $fh
print $fh "GET / HTTP/1.0 15 12 15 12";
local $/;
print <$fh>;
Using "AnyEvent::Socket::tcp_connect" gives you transparent IPv6, multi-homing, SRV-record etc. support.
For listening sockets, use "AnyEvent::Socket::tcp_server".
$fh = new Coro::Socket param => value, ...
Create a new non-blocking tcp handle and connect to the given host and port. The parameter names and values are mostly the same as for
IO::Socket::INET (as ugly as I think they are).
The parameters officially supported currently are: "ReuseAddr", "LocalPort", "LocalHost", "PeerPort", "PeerHost", "Listen", "Timeout",
"SO_RCVBUF", "SO_SNDBUF".
$fh = new Coro::Socket PeerHost => "localhost", PeerPort => 'finger';
