C++17 STL Cookbook

By: Jacek Galowicz

Overview of this book

C++ has come a long way and is in use in every area of the industry. Fast, efficient, and flexible, it is used to solve many problems. The upcoming version of C++ will see programmers change the way they code. If you want to grasp the practical usefulness of the C++17 STL in order to write smarter, fully portable code, then this book is for you. Beginning with new language features, this book will help you understand the language’s mechanics and library features, and offers insight into how they work. Unlike other books, ours takes an implementation-specific, problem-solution approach that will help you quickly overcome hurdles. You will learn the core STL concepts, such as containers, algorithms, utility classes, lambda expressions, iterators, and more, while working on practical real-world recipes. These recipes will help you get the most from the STL and show you how to program in a better way. By the end of the book, you will be up to date with the latest C++17 features and save time and effort while solving tasks elegantly using the STL.

Chapter 9. Parallelism and Concurrency

In this chapter, we will cover the following recipes:

  • Automatically parallelizing code that uses standard algorithms
  • Putting a program to sleep for specific amounts of time
  • Starting and stopping threads
  • Performing exception-safe shared locking with std::unique_lock and std::shared_lock
  • Avoiding deadlocks with std::scoped_lock
  • Synchronizing concurrent std::cout use
  • Safely postponing initialization with std::call_once
  • Pushing the execution of tasks into the background using std::async
  • Implementing the producer/consumer idiom with std::condition_variable
  • Implementing the multiple producers/consumers idiom with std::condition_variable
  • Parallelizing the ASCII Mandelbrot renderer using std::async
  • Implementing a tiny automatic parallelization library with std::future
