musl libc - https://musl.libc.org/ https://musl.libc.org/ This isn't just a small implementation of the C standard library, it's an absolute joy to read and usually every easy to understand. It takes real talent to write code which is both this legible and efficient. Often when I'm trying to understand what glibc is doing I'll read the musl version of a function and that will give me an indication of what the glibc source is trying to communicate.
