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, Iterator end);
This function attempts to connect a socket to one of a sequence of endpoints.
It does this by repeated calls to the socket's 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.
An iterator pointing to the end 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 error_code
is boost::asio::error::not_found
.
Otherwise, contains the error from the last connection attempt.
tcp::resolver r(io_service); tcp::resolver::query q("host", "service"); tcp::resolver::iterator i = r.resolve(q), end; tcp::socket s(io_service); boost::asio::connect(s, i, end);
