C++ Programming for Linux Systems

By: Desislav Andreev, Stanimir Lukanov

Overview of this book

Around 35 million Linux and almost 2 billion Android users rely on C++ for everything from the simplest embedded and IoT devices to cloud services, supercomputing, and space exploration. To help you produce high-quality software, two industry experts have transformed their knowledge and experience into practical examples in system programming with C++ Programming for Linux Systems. In this book, you'll explore the latest C++20 features, while working on multiple specific use cases. You’ll get familiar with the coroutines and modern approaches in concurrent and multithreaded programming. You'll also learn to reshape your thinking when analyzing system behavior in Linux (POSIX) environments. Additionally, you'll discover advanced discussions and novel solutions for complex challenges, while approaching trivial system operations with a new outlook and learning to choose the best design for your particular case. You can use this workbook as an introduction to system programming and software design in Linux or any Unix-based environment. You’ll also find it useful as a guideline or a supplement to any C++ book. By the end of this book, you’ll have gained advanced knowledge and skills for working with Linux or any Unix-based environment.

Getting Started with Linux Systems and the POSIX Standard

This book is about Linux and how we use C++ in Linux environments to manage critical resources. The C++ language is continuously improving, as you’ll explore in the following chapters. Before we go there, we’d like to spend some time in this chapter developing a fundamental understanding of operating systems (OSs). You are going to learn more about the origins of some specific techniques, the system call interface and the Portable Operating System Interface (POSIX).

Your choice of OS matters. Although OSs were created with a single purpose, nowadays their roles differ. Much is expected of them as well. Each OS has its own strengths and weaknesses, which we are going to discuss briefly. Linux is in widespread use across multiple technological areas and has a huge community worldwide, so it is perfect for our practical purposes. In our experience, programming in Linux or other Unix-based OS environments is rather...
