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++.

Using POSIX mutexes

This recipe will teach you how to use POSIX mutexes to synchronize access to a resource from multiple threads. We'll do this by developing a program that contains a method (the critical section) that will perform a task that cannot run concurrently. We'll use the pthread_mutex_lockpthread_mutex_unlock, and pthread_mutex_init POSIX methods to synchronize the threads' access to it.

How to do it...

In this recipe, we'll create a multi-threaded program just to increment an integer to 200000. To do this, we'll develop the critical section that's responsible for incrementing the counter, which must be protected. Then, we'll develop the main section...
