How resume the execution of a stackful coroutine in the context of its strand?

Question

using Yield = asio::yield_context;
using boost::system::error_code;
int Func(Yield yield) {
  error_code ec;
  asio::detail::async_result_init

        

Answer 1

You are complicating things by creating threads out of the executor framework provided by Boost Asio.

For this reason you shouldn't assume that what you want is possible. I strongly suggest just adding more threads to the io_service and letting it manage the strands for you.

Or, you can extend the library and add the new feature you apparently want. If so, it's a good idea to contact the developer mailing list for advice. Perhaps they welcome this feature¹?
