def connect_from(*args, timeout: nil, &block)
  connect_internal(family_addrinfo(*args), timeout, &block)
end

creates a socket connected to the address of self.

If one or more arguments given as local_addr_args, it is used as the local address of the socket. local_addr_args is given for family_addrinfo to obtain actual address.

If local_addr_args is not given, the local address of the socket is not bound.

The optional last argument opts is options represented by a hash. opts may have following options:

:timeout: specify the timeout in seconds.

If a block is given, it is called with the socket and the value of the block is returned. The socket is returned otherwise.

Example

Addrinfo.tcp("www.ruby-lang.org", 80).connect_from("0.0.0.0", 4649) {|s|
  s.print "GET / HTTP/1.0\r\nHost: www.ruby-lang.org\r\n\r\n"
  puts s.read
}

# Addrinfo object can be taken for the argument.
Addrinfo.tcp("www.ruby-lang.org", 80).connect_from(Addrinfo.tcp("0.0.0.0", 4649)) {|s|
  s.print "GET / HTTP/1.0\r\nHost: www.ruby-lang.org\r\n\r\n"
  puts s.read
}
