on an
existing native descriptor.
basic_stream_descriptor( asio::io_service & io_service, const native_handle_type & native_descriptor);
This constructor creates a stream descriptor object to hold an existing native descriptor.
The io_service
object that the stream descriptor will use to dispatch handlers
for any asynchronous operations performed on the descriptor.
The new underlying descriptor implementation.
