Coro::Socket - non-blocking socket-I/O
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, );
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.
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\015\012\015\012"; local $/; print <$fh>;
Using AnyEvent::Socket::tcp_connect gives you transparent IPv6, multi-homing, SRV-record etc. support.
AnyEvent::Socket::tcp_connect
For listening sockets, use AnyEvent::Socket::tcp_server.
AnyEvent::Socket::tcp_server
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.
ReuseAddr
LocalPort
LocalHost
PeerPort
PeerHost
Listen
Timeout
SO_RCVBUF
SO_SNDBUF
$fh = new Coro::Socket PeerHost => "localhost", PeerPort => 'finger';
