I believe such document doesn't exist. As it's been suggested to you,
reading and learning for the codebase comes closest.
However, you probably will be interested in general documentation on
"C semantics". Look out for things like infamous UB (undefined
behaviour), implicit type and arithmetic conversions (pitfalls of mixing
signed and unsigned integers is one example), secure coding, etc.
A few pointers to get you started:
- C89/C99/C11/C17/C23 standards
(copies of final drafts are available online for free)
- SEI CERT C Coding Standards
- MISRA C
- "Expert C programming" by Peter van der Linden
- "How to C in 2016" by Matt Stancliff
Beware some advice and guidelines found in these documents will be very
opinionated.
