Alternative to deprecated get_io_service()

Question

Asio v 1.11. The doc says that basic_stream_socket::get_io_service() member function is deprecated and get_executor() must be used instead. But the latter returns executor not io_service.

How to obtain reference to the io_service object used by socket to construct another one?

Answer 1

You can use get_executor().context():

socket newSocket(existingSocket.get_executor().context()));

Answer 2

Since ASIO v 1.13 new I/O object can be constructed using just the executor:

socket new_socket{existing_socket.get_executor()};

Answer 3

Since I don't have enough reputation points to comment, I write as an answer:

Using get_executor().context() did not work right away for me, but writing a macro did (see this answer)
