DESCRIPTIONThis 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 WARNINGThis 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); # 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.
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".
