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++.

Killing a process

In the previous recipe, we've seen two ways to start a new process where the parent always waits for their children to finish the task. This is not always the case. Sometimes, a parent should be able to kill the child process. In this recipe, we will see an example of how to do that.

Getting ready

It's important to go through the Starting a new process recipe as a prerequisite.

How to do it...

In this section, we create a program where a parent process forks its child process, the child process will do an infinite loop...
