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++.

Learning how to use the oldest form of IPC – pipes

In the previous recipe, you learned how to choose an IPC based on some key factors. It's now time to get hands-on with the four communication types, and this recipe focuses on pipes. In this recipe, you'll learn how to use pipes to make two processes communicating full-duplex by using two pipes. We'll not use any form of synchronization as generally, it is not required. In the How it works... section, we'll see why and when is it not required.

How to do it...

In this section, we'll develop a program that will create two processes, with the unique goal of sending a message to each other. With a pipe, as we've seen, the data flows in...
