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++.

Dealing with Processes and Threads

Processes and threads are the foundations of any computation. A program is rarely made of just one thread or process. In this chapter, you will learn the fundamental recipes for dealing with threads and processes. You will also learn how easy and convenient it is to deal with threads compared with the Portable Operating System Interface (POSIX). Learning these skills is very important as part of the core skills of a system developer. C++ does not have the notion of process in its standard library, so the Linux native implementation will be used.

This chapter will cover the following recipes:

  • Starting a new process
  • Killing a process
  • Creating a new thread
  • Creating a daemon process
