C system programing interactive demo

1. the most basic C program possible: main(){}

2. hello world

3. What is a system call?

   • Synchronously ask Linux to do something for you as a user program

   • Student examples: open, read, write, close

   • Use these with file descriptors to do file I/O without FILE *

   • Use man 2 xxx to learn about system call xxx

4. Working with processes

   • execve: transform one process into another

   • fork: split one process in two

   • wait: wait for a child process
