Advanced Programming in the #UNIX Environment
Week 2: read(2)/write(2)/lseek(2)
In this video lecture, we will go into the details of the read(2), write(2), and lseek(2). We'll also do a few weird things with file descriptors, and take a look at how we can ensure I/O efficiency when making these system calls.

Advanced Programming in the #UNIX Environment Week 2: File Sharing In this final video lecture segment for our week 2 materials, we take a look at what it means when multiple processes access the same files and what the implications of that are on the syscalls we know. We conclude with a look at /dev/fd on different operating systems, including #NetBSD, #macOS, and #Linux. https://youtu.be/CAbUtc86ULw
