Overview of this book

C++ is a general-purpose programming language with a bias toward system programming as it provides ready access to hardware-level resources, efficient compilation, and a versatile approach to higher-level abstractions. This book will help you understand the benefits of system programming with C++17. You will gain a firm understanding of various C, C++, and POSIX standards, as well as their respective system types for both C++ and POSIX. After a brief refresher on C++, Resource Acquisition Is Initialization (RAII), and the new C++ Guideline Support Library (GSL), you will learn to program Linux and Unix systems along with process management. As you progress through the chapters, you will become acquainted with C++'s support for IO. You will then study various memory management methods, including a chapter on allocators and how they benefit system programming. You will also explore how to program file input and output and learn about POSIX sockets. This book will help you get to grips with safely setting up a UDP and TCP server/client. Finally, you will be guided through Unix time interfaces, multithreading, and error handling with C++ exceptions. By the end of this book, you will be comfortable with using C++ to program high-quality systems.

Programming POSIX Sockets Using C++

In this chapter, you will learn how to program POSIX sockets using C++17, including more common C++ paradigms, such as Resource Aquisition Is Initialization (RAII). To begin with, this chapter will discuss what a socket is, and the difference between UDP and TCP. The POSIX APIs will be explained in detail prior to walking you through five different examples. The first example will step you through programming with POSIX sockets by creating a UDP echo server example. The second example will create this same example using TCP instead of UDP and explain the differences. The third example will expand upon our existing debug logger that has been created in previous chapters, while the fourth and fifth examples will explain how to safely process a packet.

In this chapter, we will cover the following topics:

  • POSIX sockets
  • Leveraging C++ and RAII...
