With this book, we aim to provide you with an understanding of Linux/Unix system programming, a reference manual on Linux system calls, and an insider's guide to writing smarter, faster code using C++. The book will explain the differences between POSIX standard functions and special services offered by modern C++.
This book will also teach the reader about basic I/O operations, such as reading from, and writing to, files, advanced I/O interfaces, memory mappings, optimization techniques, thread concepts, multithreaded programming, POSIX threads, interfaces for allocating memory and optimizing memory access, basic and advanced signal interfaces, and their role on the system. This book will also explain clock management, including POSIX clocks and high-resolution timers. Finally, this book uses modern examples and references to provide up-to-date relevance to C++ and the wider community, including the Guideline Support Library and its role in system programming.

This book is for beginner to advanced Linux and general UNIX programmers working with C++, or anyone looking for a general overview of Linux, C++17, and/or systems programming with POSIX, C, and C++. Although this book covers a lot of topics on modern C++, its focus is on system programming. It is expected that the reader already has a general familiarity with C and C++, as both will be leveraged throughout this book.

, Getting Started with System Programming, lays the foundation for the book, helping to define what system programming is by providing some basic examples and explaining the benefits of system programming with C++.

, Learning the C, C++17, and POSIX Standards, reviews the C, C++, and POSIX standards, providing an overview of the facilities provided by each standard with respect to system programming, as well as a general overview of the topics that will be discussed throughout this book.

, System Types for C and C++, provides a comprehensive overview of the system types that are provided by C and C++ and how they are used when carrying out system programming. This chapter will also discuss many of the pitfalls associated with the native types and how to overcome them.

, C++, RAII, and the GSL Refresher, provides a general overview of the additions provided by C++17. This chapter will also discuss the benefits of Resource Acquisition Is Initialization (
