PintOS is a pint-sized operating system made for students to learn about operating systems concepts.
When writing pintos code, it was sometimes helpful to write demos to show functionality in a smaller code space.
It is sufficient to compile each test with gcc *.c. To get an understanding of what each demo does, check out the appropiate main.c file.
Most of the files in the hash_key_demo folder are from the pintos kernel library. I had to change some stuff to get it to work since pintos has its own version of c.
keyed_hash is a file that only follows the api for the main pintos hash. It uses casting magic and simplifies the pintos hash api.
The main pintos hash api also takes advantage of the pintos linked list. I think the linked list is cool because it is done without any dynamic allocation! That's not what this demo is about though..
This was my first introduction to both memcpy and writing macros. The PUSH and POP macros are designed to work with data of any size.
I wasn't able to get static blocks working in pintos, nor did it make the most sense to. However, I spent a lot of time trying to figure out how, and I think the way I did it was pretty cool.
