C++ System Programming Cookbook

By: Onorato Vaticone

Overview of this book

C++ is the preferred language for system programming due to its efficient low-level computation, data abstraction, and object-oriented features. System programming is about designing and writing computer programs that interact closely with the underlying operating system and allow computer hardware to interface with the programmer and the user. The C++ System Programming Cookbook will serve as a reference for developers who want to have ready-to-use solutions for the essential aspects of system programming using the latest C++ standards wherever possible. This C++ book starts out by giving you an overview of system programming and refreshing your C++ knowledge. Moving ahead, you will learn how to deal with threads and processes, before going on to discover recipes for how to manage memory. The concluding chapters will then help you understand how processes communicate and how to interact with the console (console I/O). Finally, you will learn how to deal with time interfaces, signals, and CPU scheduling. By the end of the book, you will become adept at developing robust systems applications using C++.

Synchronization building blocks

From this recipe and the next two, we'll be back in the C++ world. In this recipe, we'll learn about the C++ synchronization building blocks. Specifically, we'll look at using std::lock_guard and std::unique_lock in combination with Resource Acquisition Is Initialization (RAII), an object-oriented programming idiom that makes the code more robust and readable. std::lock_guard and std::unique_lock wrap the C++ concept of mutexes around two classes with the RAII concept. std::lock_guard is the simplest and smallest guard, while std::unique_lock adds some functionality on top of it.
