From e244401ce508ad391295beb636e499fcc6797a2a Mon Sep 17 00:00:00 2001 From: "Gregory P. Smith" Date: Mon, 23 Jan 2023 21:20:53 -0800 Subject: [docs] Mention how to get/set a bigint PyLong via the C API (#101270) We don't need direct C APIs to get at a bigint representation of PyLong but we do want the few people who need to understand how.
