I'm in the process of writing an introduction. You can find a draft here:
It should get them started. Everything else is documented in the
Thanks. I'd suggest the following additions:
1. Please discuss error handling early on. How errors are handled is arguably the most subtle point of the API.
2. Please discuss the lifetime of environments and values. This is also extremely subtle and can easily lead to undefined behavior.
3. Please add explicit checks for the size of structures. If the actual structure passed from Emacs is smaller than the expected structure, undefined behavior will happen if one of the "excess" members is accessed.
4. You should also mention how Emacs deals with stack overflow, because that can lead to inconsistent data structures and undefined behavior as well.
I'm writing a reference and a set of caveats for modules, unfortunately progress is very slow on my part.
