How to implement a spinlock / event / semaphore
Multi-threading has been the theme of my previous two classes where I discussed thread-pools and producer-consumer queues. Let’s talk about the fundamental aspects of multi-threading and some of its most basic building blocks: spinlocks, automatic and manual events, and semaphores.
In this week’s class I will show you how to implement these building blocks using only standard C++ components:
std::atomic_flag,
std::mutex,
std::condition_variable.
Code from the class:
lesson_spinlock_event_semaphore_how_to.cpp
Complete implementation:
mutex.hpp | event.hpp | semaphore.hpp
