9 use Coro::Socket;
10
11 # listen on an ipv4 socket
12 my $socket = new Coro::Socket PeerHost => "localhost",
13 PeerPort => 'finger';
14
15 # listen on any other type of socket

18 Local => "/tmp/socket",
19 Type => SOCK_STREAM,

23 This module is an AnyEvent user, you need to make sure that you use and
24 run a supported event loop.
25
26 This module implements socket-handles in a coroutine-compatible way,
27 that is, other coroutines can run while reads or writes block on the
28 handle. See Coro::Handle, especially the note about prefering method
29 calls.
30
32 This module was written to imitate the IO::Socket::INET API, and derive
33 from it. Since IO::Socket::INET does not support IPv6, this module does
34 neither.
35
36 Therefore it is not recommended to use Coro::Socket in new code.
37 Instead, use AnyEvent::Socket and Coro::Handle, e.g.:
38
39 use Coro;
40 use Coro::Handle;
41 use AnyEvent::Socket;
42
43 # use tcp_connect from AnyEvent::Socket
44 # and call Coro::Handle::unblock on it.
45
46 tcp_connect "www.google.com", 80, Coro::rouse_cb;
47 my $fh = unblock +(Coro::rouse_wait)[0];
48
49 # now we have a perfectly thread-safe socket handle in $fh
50 print $fh "GET / HTTP/1.0\015\012\015\012";
51 local $/;
52 print <$fh>;
53
54 Using "AnyEvent::Socket::tcp_connect" gives you transparent IPv6,
55 multi-homing, SRV-record etc. support.
56
57 For listening sockets, use "AnyEvent::Socket::tcp_server".
58
59 $fh = new Coro::Socket param => value, ...
60 Create a new non-blocking tcp handle and connect to the given host
61 and port. The parameter names and values are mostly the same as for
62 IO::Socket::INET (as ugly as I think they are).
63
64 The parameters officially supported currently are: "ReuseAddr",
65 "LocalPort", "LocalHost", "PeerPort", "PeerHost", "Listen",
66 "Timeout", "SO_RCVBUF", "SO_SNDBUF".
67
68 $fh = new Coro::Socket PeerHost => "localhost", PeerPort => 'finger';
