OS-demo-programs

A collection of short demonstration programs from a decade+ of OS class.

I have taught the junior/senior level operating systems class at Saint Louis University since 2001, usually every other year. The class is more of a systems programming class, in that we don't actually write or alter the OS itself.

Along the way, I created a number of short C/C++ programs to demonstrate operating system behavior. The use of these programs may not be obvious, or well commented. I will try to improve that over time.

They are organized into eight directories based on topic:

• basic : command line arguments, stdin/out/err, errno and perror
• fork : process management with fork, exec
• ipc : interprocess communication with pipes and signals
• threads : pthread threads and synchronization
• security : security issues
• memory : memory management, pointers, TLB and stacks
• file : disk and file issues
• network : networking with sockets
