Summary

Explore how semaphores function as key tools for synchronization and event ordering in concurrent programming. Understand their role in solving classic problems and gain insights into effective use and design considerations to deepen your concurrency expertise.

We'll cover the following...

Semaphores are a powerful and flexible primitive for writing concurrent programs. Some programmers use them exclusively, shunning locks and condition variables, due to their simplicity and utility.

In this chapter, we have presented just a few classic problems and solutions. If you are interested in finding out more, there are many other materials you can reference. One great (and free reference) is ...
