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++.

Smart pointers – unique_ptr and shared_ptr

This recipe will show the basic usage of unique_ptr and shared_ptr. These smart pointers are the main helpers for programmers who don't want to deal with memory deallocation manually. Once you've learned how to use them properly, this will save headaches and nights of debugging sessions.

How to do it...

In this section, we'll look at the basic use of two smart pointers, std::unique_ptr and std::shared_ptr:

  1. Let's develop a unique_ptr example by developing the following class:
#include <iostream>
#include <memory>
class CruiseControl
{
public:
CruiseControl()
{
std::cout << "CruiseControl object created" &lt...
