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++.

Understanding C++ primitive types

This recipe will show all the primitive data types defined by the C++ standard, as well as their size.

How to do it...

In this section, we'll have a closer look at what primitives the C++ standard defines and what other information is important. We'll also learn that although the standard does not define a size for each, it defines another important parameter:

  1. First, open a new Terminal and type in the following program:
#include <iostream>
#include <limits>

int main ()
{
// integral types section
std::cout << "char " << int(std::numeric_limits<char>::min())
<< "-" << int(std::numeric_limits<char...
