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.

Pthreads – a few random tips and FAQs

To conclude this chapter, we provide answers to FAQs on multithreading as well as a brief note on how to debug a MT application using GDB. Do read on.

Every function in your MT application that can be run in parallel by threads must be written, verified, and documented to be thread-safe. This includes your MT app code, your project libraries, as well as any third-party libraries you link into.
