(Deprecated: Use range overload.) Establishes a socket connection by trying each endpoint in a sequence.
template< typename Protocol, typename Executor, typename Iterator> Iterator connect( basic_socket< Protocol, Executor > & s, Iterator begin, typename constraint<!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 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.
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 asio::error::not_found
.
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 asio::ip::tcp::resolver::iterator
.
