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.

Registering a function to be called when a program exits normally


It is common that a program, upon exit, must perform cleanup code to release resources, or write something to a log, or do some other end operation. The standard library provides two utility functions that enable us to register functions to be called when a program terminates normally, either by returning from main() or through a call to std::exit() or std::quick_exit(). This is particularly useful for libraries that need to perform an action before the program is terminated, without relying on the user to explicitly call an end function. In this recipe, you will learn how to install exit handlers and how they work.

Getting ready

All the functions discussed in this recipe, exit(), quick_exit(), atexit(), and at_quick_exit(), are available in the namespace std in the header <cstdlib>.

How to do it...

To register functions to be called upon termination of a program, you should use the following:

  • std::atexit() to register functions...
