How processes get more memory. (mmap, brk)

We've all called malloc to get more memory for our programs, but what is REALLY happening when we call malloc? This video goes under the hood and shows you how a computer process (running computer program) gets more memory from the operating system.

Welcome to my channel.. 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.

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.
