Overview of this book

C++ is one of the most widely used programming languages. Fast, efficient, and flexible, it is used to solve many problems. The latest versions of C++ have seen programmers change the way they code, giving up on the old-fashioned C-style programming and adopting modern C++ instead. Beginning with the modern language features, each recipe addresses a specific problem, with a discussion that explains the solution and offers insight into how it works. You will learn major concepts about the core programming language as well as common tasks faced while building a wide variety of software. You will learn about concepts such as concurrency, performance, meta-programming, lambda expressions, regular expressions, testing, and many more in the form of recipes. These recipes will ensure you can make your applications robust and fast. By the end of the book, you will understand the newer aspects of C++11/14/17 and will be able to overcome tasks that are time-consuming or would break your stride while developing.

Implementing a thread-safe singleton

Singleton is probably one of the most well-known design patterns. It restricts the instantiation of a single object of a class, something that is necessary in some cases, although many times the use of a singleton is rather an anti-pattern that can be avoided with other design choices. Since a singleton means a single instance of a class is available to an entire program, it is likely that such a unique instance might be accessible from different threads. Therefore, when you implement a singleton, you should also make it thread-safe. Before C++11, doing that was not an easy job, and a double-checked locking technique was the typical approach. However, Scott Meyers and Andrei Alexandrescu showed, in a paper called C++ and the Perils of Double-Checked Locking, that using this pattern did not guarantee a thread-safe singleton implementation in portable C++. Fortunately, this...
