Systems Programming Toolkit

Three small Linux systems programs in C, each exercising a different OS mechanism directly: process control, thread synchronization, and raw filesystem I/O.

Project	Mechanism
pman/	Process management — fork/exec, signals, /proc parsing
airline-checkin-sim/	Concurrency — pthreads, mutexes, condition variables
fat12-toolkit/	Filesystems — mmap, raw FAT12 parsing and on-disk writes

Stack

C (C11), POSIX APIs directly — no libraries. Each project is a plain Makefile.

Platform note

All three use Linux-specific APIs directly (fork/exec, /proc/<pid>/stat, pthread.h, mmap) rather than portable wrappers, so they need a Linux environment (or WSL) to build. Confirmed on this checkout: none build under Windows/MinGW, because MinGW ships neither sys/wait.h, pthread.h, nor sys/mman.h. On Linux, each just needs make.

🎓 Project Context

Built as part of CSC 360: Operating Systems at the University of Victoria (Fall 2024).
