When an agent writes the code, the bottleneck moves upstream: how clearly can you express the idea? Documentation isn’t the interruption anymore. It’s the leverage....

Introduction This post is about using C++ coroutines to suspend and resume functions in real time. The objective is a simple way of building real time tasks using only C++, without the need for an RTOS or operating system kernel. Coroutines are functions that can be suspended and resumed, using...

Creating the coroutines runtime infrastructure A simple coroutine example was presented in “C++20 coroutines, header only, without an OS”. This post describes the runtime used for that example in detail. This story is also published on Medium. Summary of the runtime files The runtime for this example is a set...
