[asio-users] How to wait for completion of all stackful coroutines?

[Nikita Chumakov]

Hi,

I'm starting a number of coroutines with asio::spawn, and I want to wait
until all of then are finished and do some other work then. How it can
be done?

The control flow is following:

asio::spawn (io, [] (asio::yield_context yield) {
...
// starting few coroutines
asio::spawn (yield, [] (asio::yield_context yield2) { ... });
asio::spawn (yield, [] (asio::yield_context yield2) { ... });
asio::spawn (yield, [] (asio::yield_context yield2) { ... });
asio::spawn (yield, [] (asio::yield_context yield2) { ... });

// now I want to wait for all of them to finish before I do
// some other work?
...
});

io.run ();

Regards,
Nikki
