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';

NAME

       Coro::Signal - thread signals (binary semaphores)

SYNOPSIS

	use Coro;

	$sig = new Coro::Signal;

	$sig->wait; # wait for signal

	# ... some other "thread"

	$sig->send;

DESCRIPTION

       This module implements signals/binary semaphores/condition variables (basically all the same thing). You can wait for a signal to occur or
       send it, in which case it will wake up one waiter, or it can be broadcast, waking up all waiters.

       It is recommended not to mix "send" and "broadcast" calls on the same "Coro::Signal" - it should work as documented, but it can easily
       confuse you :->

       You don't have to load "Coro::Signal" manually, it will be loaded automatically when you "use Coro" and call the "new" constructor.

       $sig = new Coro::Signal;
	   Create a new signal.

       $sig->wait
	   Wait for the signal to occur (via either "send" or "broadcast"). Returns immediately if the signal has been sent before.

       $sem->wait ($callback)
	   If you pass a callback argument to "wait", it will not wait, but immediately return. The callback will be called under the same
	   conditions as "wait" without arguments would continue the thrad.

	   The callback might wake up any number of threads, but is NOT allowed to block (switch to other threads).

       $sig->send
	   Send the signal, waking up one waiting process or remember the signal if no process is waiting.

       $sig->broadcast
	   Send the signal, waking up all waiting process. If no process is waiting the signal is lost.

       $sig->awaited
	   Return true when the signal is being awaited by some process.
