How do you implement Coroutines in C++

by

Yes it can be done without a problem. All you need is a little assembly code to move the call stack to a newly allocated stack on the heap.

I would look at the boost::coroutine library.

The one thing that you should watch out for is a stack overflow. On most operating systems overflowing the stack will cause a segfault because virtual memory page is not mapped. However if you allocate the stack on the heap you don’t get any guarantee.
Just keep that in mind.
