NAME

       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/1.015121512";
	  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';
