Hi Professor, I am not very familiar with c++, but I want to implement asynchronous operations, but MC_AWAIT reports an error.

Hi Professor, I am not very familiar with c++, but I want to implement asynchronous operations, but MC_AWAIT reports an error.
std::thread th1( [& theirHashes](){MC_AWAIT(chl.recv(theirHashes));});

That could work if you did

std::thread th1( [& theirHashes](){ macoro::sync_wait(chl.recv(theirHashes));});

But it's quite inefficient to spawn a thread to send one thing.

I'm generally, MC_AWAIT can only go inside a MC_BEGIN, MC_END coroutine block. See https://github.com/Visa-Research/coproto/blob/main/frontend/cpp14Tutorial.cpp

If you have c++ 20 you could also enable that and use the language support for coroutines.

If it's a one off thing then you can do the thread thing. Again, I made a long tutorial to inform people how to do this more efficiently. Take a look at it.
