Using Coroutines in C++ for System Programming

We are almost at the end of our book. The final chapter is dedicated to a feature that is very useful for the purposes of system programming but is fairly new to the C++ standard. Coroutine objects found their application fast, becoming first-class state machine objects. Their power is in hiding logic behind the coroutine frame. Be advised that this is an advanced topic, and the coroutine interface of C++ is neither simple nor comfortable to use. It is well thought out but definitely not the most user-friendly in comparison to other programming languages.

In this chapter, you will learn the basics of using this facility. If you are new to it, then you’ll spend some time understanding its requirements. You’ll have an easier time with coroutines if you have previous experience with them in other programming languages. Still, we will use this chapter to propose their application in system programming.

We will present two...
