Establishes a socket connection by trying each endpoint in a sequence.
template< typename Protocol, typename SocketService, typename Iterator> Iterator connect( basic_socket< Protocol, SocketService > & s, Iterator begin);
This function attempts to connect a socket to one of a sequence of endpoints.
It does this by repeated calls to the socket's
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.
On success, an iterator denoting the successfully connected endpoint. Otherwise, the end iterator.
Thrown on failure. If the sequence is empty, the associated
Otherwise, contains the error from the last connection attempt.
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
tcp::resolver r(io_service); tcp::resolver::query q("host", "service"); tcp::socket s(io_service); boost::asio::connect(s, r.resolve(q));
