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 manipulate I/O strings

String manipulation is a very important aspect of almost any software. Being able to manipulate strings simply and effectively is a key aspect of software development. How would you read the configuration file of your application or parse it? This recipe will teach you what tools C++ offers to make this an enjoyable task with the std::stringstream class. 

How to do it...

In this section, we'll develop a program by using std::stringstream to parse streams, which can actually come from any source: files, strings, input arguments, and so on.

  1. Let's develop a program that prints all the entries of a file. Type the following code into a new CPP file, console_05.cpp:
