Returns an Addrinfo object for local address obtained by getsockname.

Note that addrinfo.protocol is filled by 0.

TCPSocket.open("www.ruby-lang.org", 80) {|s|
  p s.local_address #=> #<Addrinfo: 192.168.0.129:36873 TCP>
}

TCPServer.open("127.0.0.1", 1512) {|serv|
  p serv.local_address #=> #<Addrinfo: 127.0.0.1:1512 TCP>
}

creates an Addrinfo object from the arguments.

The arguments are interpreted as similar to self.

Addrinfo.tcp("0.0.0.0", 4649).family_addrinfo("www.ruby-lang.org", 80)
#=> #<Addrinfo: 221.186.184.68:80 TCP (www.ruby-lang.org:80)>

Addrinfo.unix("/tmp/sock").family_addrinfo("/tmp/sock2")
#=> #<Addrinfo: /tmp/sock2 SOCK_STREAM>

creates a new Socket connected to the address of local_addrinfo.

If local_addrinfo is nil, the address of the socket is not bound.

The timeout specify the seconds for timeout. Errno::ETIMEDOUT is raised when timeout occur.

If a block is given the created socket is yielded for each address.
