NAME

Coro::Socket - non-blocking socket-io

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 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.

$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 in IO::Socket::INET (as ugly as I think they are).

If the host is unreachable or otherwise cannot be connected to this method returns undef. On all other errors ot croak's.

Multihomed is always enabled.

    $fh = new Coro::Socket PeerHost => "localhost", PeerPort => 'finger';
