Hands-On System Programming with Linux

By: Kaiwan N. Billimoria, Tigran Aivazian

Overview of this book

The Linux OS and its embedded and server applications are critical components of today’s software infrastructure in a decentralized, networked universe. The industry's demand for proficient Linux developers is only rising with time. Hands-On System Programming with Linux gives you a solid theoretical base and practical industry-relevant descriptions, and covers the Linux system programming domain. It delves into the art and science of Linux application programming— system architecture, process memory and management, signaling, timers, pthreads, and file IO. This book goes beyond the use API X to do Y approach; it explains the concepts and theories required to understand programming interfaces and design decisions, the tradeoffs made by experienced developers when using them, and the rationale behind them. Troubleshooting tips and techniques are included in the concluding chapter. By the end of this book, you will have gained essential conceptual design knowledge and hands-on experience working with Linux system programming interfaces.

Linux Memory Issues

A simple truism: memory issues exist. The very fact that we program in languages such as C (and C++) implicitly gives rise to literally infinite types of issues! At some point, one realizes (perhaps a bit pessimistically) that programming with care in a managed memory-safe language is ultimately the (only?) realistic way to avoid memory issues altogether.

However, here we are, working with our power tool of choice: the eminent and venerable C programming language! So, what we can do to mitigate, if not eliminate, common memory issues, is the topic of this chapter. Ultimately, the goal is to be truly memory-safe; well, that's easier said than done!

Nevertheless, we shall attempt to have the developer successfully undertake this task by throwing light on the common memory issues they will likely face. In the chapter that follows, we will look into how some...
