In this video, I show you how a pipe is created and reconnected (using dup2). We look at how popen works, provide some information about file descriptors (fdopen), and we implement our own better version of popen (called popen3) that captures stdout, stderr, and stdin in one call.

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. About me: I'm a computer scientist, electrical engineer, researcher, and teacher. I specialize in embedded systems, mobile computing, sensor networks, and the Internet of Things. I teach systems and networking courses at Clemson University, where I also lead the PERSIST research lab.
