(Deprecated: Use range overload.) Asynchronously establishes a socket connection by trying each endpoint in a sequence.
template<
    typename Protocol,
    typename Executor,
    typename Iterator,
    typename IteratorConnectHandler = DEFAULT>
DEDUCED async_connect(
    basic_socket< Protocol, Executor > & s,
    Iterator begin,
    IteratorConnectHandler && handler = DEFAULT,
    typename enable_if<!is_endpoint_sequence< Iterator >::value >::type *  = 0);
          This function attempts to connect a socket to one of a sequence of endpoints.
          It does this by repeated calls to the socket's async_connect
          member function, once for each endpoint in the sequence, until a connection
          is successfully established.
        
The socket to be connected. If the socket is already open, it will be closed.
An iterator pointing to the start of a sequence of endpoints.
The handler to be called when the connect operation completes. Copies will be made of the handler as required. The function signature of the handler must be:
void handler( // Result of operation. if the sequence is empty, set to // boost::asio::error::not_found. Otherwise, contains the // error from the last connection attempt. const boost::system::error_code& error, // On success, an iterator denoting the successfully // connected endpoint. Otherwise, the end iterator. Iterator iterator );
                Regardless of whether the asynchronous operation completes immediately
                or not, the handler will not be invoked from within this function.
                On immediate completion, invocation of the handler will be performed
                in a manner equivalent to using post.
              
          This overload assumes that a default constructed object of type Iterator
          represents the end of the sequence. This is a valid assumption for iterator
          types such as boost::asio::ip::tcp::resolver::iterator.
