		Socket.bind(address, **@options, &block)
	end
end

#connect {|Socket| ... } ⇒ Socket

Try to connect to the given host by connecting to each address in sequence until a connection is made.

Yields:

  • (Socket) —

    the socket which is being connected, may be invoked more than once

Returns:

  • (Socket) —

    the connected socket

Raises:

  • if no connection could complete successfully
