What I need is a way for each call to bottleneck() to fully complete before the next one starts, and each call occurs in the order they were called. This would make the output 3 2 1 0. I also want to allow other asynchronous routines on the io_service to run when the coroutine is yielding (so no cheating and turning the delay timer into a sleep).
Take a look at this project: https://github.com/blinktrade/iofiber It should solve your needs. You could... like: spawn(ioservice, [](fiber::this_fiber this_fiber) { spawn(this_fiber, std::bind(&bottleneck, 3s, _1)) .join(this_fiber); spawn(this_fiber, std::bind(&bottleneck, 2s, _1)) .join(this_fiber); spawn(this_fiber, std::bind(&bottleneck, 1s, _1)) .join(this_fiber); spawn(this_fiber, std::bind(&bottleneck, 0s, _1)) .join(this_fiber); }) .detach(); With IOFiber, spawn() returns a fiber handle that you can use to join() the fiber. The handle is moveable and then you can pass it around. Check the documentation. -- Vinícius dos Santos Oliveira https://vinipsmaker.github.io/
