Construct a basic_seq_packet_socket
without opening it.
template< typename ExecutionContext> basic_seq_packet_socket( ExecutionContext & context, typename constraint< is_convertible< ExecutionContext &, execution_context & >::value >::type = 0);
This constructor creates a sequenced packet socket without opening it. The socket needs to be opened and then connected or accepted before data can be sent or received on it.
An execution context which provides the I/O executor that the socket will use, by default, to dispatch handlers for any asynchronous operations performed on the socket.
