How one thread listens to many sockets with select in C. // Ever wondered how to concurrently monitor multiple network connections (sockets) without creating multiple threads? This video shows you how with select(), a universally-available call that so many programmers don't know exists. This is a network-oriented video that shows how select works in a socket server example, written in C, but this technique works with any file descriptor, including files and pipes.

This is also the first of what I expect to be a series of videos on asynchronous I/O and event-driven systems.

Welcome! I post videos that help you learn to program and become a more confident software developer. I cover beginner-to-advanced systems topics ranging from network programming, threads, processes, operating systems, embedded systems and others. My goal is to help you get under-the-hood and better understand how computers work and how you can use them to become stronger students and more capable professional developers.
