Companion C code examples for the free Operating Systems: Three Easy Pieces (OSTEP) textbook, organized by chapter. It covers CPU virtualization and scheduling, memory virtualization and paging, concurrency with threads and locks, and persistence including file systems and distributed systems.

Use cases

• learn operating systems concepts with runnable C examples
• study thread synchronization with locks, condition variables, and semaphores
• understand how paging, segmentation, and TLBs work in practice
• explore CPU scheduling algorithms like MLFQ and lottery scheduling
• see file system implementation examples like FFS, LFS, and journaling
• accompany self-study or a university OS course using OSTEP

When to choose

• you are reading OSTEP and want the book's code samples
• you want small, self-contained C programs illustrating OS concepts
• you are teaching an operating systems course and need example code

When to avoid

• you need a production-ready OS library or framework
• you want a complete operating system or kernel to run
• you need licensed, maintained software - the repo has no license
