The Linux OS and its embedded and server applications are critical components of today’s key software infrastructure in a decentralized and networked universe. Industry demand for proficient Linux developers is ever-increasing. This book aims to give you two things: a solid theoretical base, and practical, industry-relevant information—illustrated by code—covering the Linux system programming domain. This book delves into the art and science of Linux system programming, including system architecture, virtual memory, process memory and management, signaling, timers, multithreading, scheduling, and file I/O.
This book attempts to go beyond the use API X to do Y approach; it takes pains to explain the concepts and theory required to understand the programming interfaces, the design decisions, and trade-offs made by experienced developers when using them and the rationale behind them. Troubleshooting tips and industry best practices round out the book’s coverage. By the end of this book, you will have the conceptual knowledge, as well as the handson experience, needed for working with Linux system programming interfaces.
