Establishes a socket connection by trying each endpoint in a sequence.
template< typename Protocol, typename Iterator> Iterator connect( basic_socket< Protocol > & 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
function, once for each endpoint in the sequence, until a connection is
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.
An iterator denoting the successfully connected endpoint.
Thrown on failure. If the sequence is empty, the associated
boost::asio::error::not_found. Otherwise, contains
the error from the last connection attempt.
