Coroutines

It's a typical requirement for thread management to synchronize them. One thread prepares, in this case, a work-package another thread is waiting for. 

My story to coroutines in C++20 goes on. Today I dive deep into the coroutines framework to create an infinite data stream. You have to read the two previous posts, "C++20: Coroutines - A First Overview", and "C++20: More Details to Coroutines" to be prepared. 

After I gave you in my last post (C++20: Coroutines - A First Overview) my first impression of coroutines, I want to provide more details today. Once more, we get in C++20 not coroutines but a framework for building coroutines. 

C++20 provides four features that change how we think about and write modern C++: concepts, the ranges library, coroutines, and modules. I already wrote a few posts to concepts and the ranges library. Let's have a closer look at coroutines. 

This post presents you the big four: concepts, ranges, coroutines, and modules.

Coroutines are functions that can suspend and resume their execution while keeping their state. The evolution in C++20 goes one step further.
