Where can I find a good guide to writing C Collections?

Question

I remember having read a very good guide to writing collections. By that I mean, it described using macros to generate types with type parameters, kind of like C++ templates. I'm not sure if it was written by Rusty Russell, but it was someone I recognized. It was posted on hackernews or proggit... I wanted to write a new C library and has searched google for the past 30 min for this guide to no avail. Anybody remember?

Answer 1

This guide fits your description:

• Collections in C by Armin Ronacher.

Answer 2

One example would be queue(3), see queue.h.
