From a0b4da22978b0a062cc7a0c0127904ccc4abf5c2 Mon Sep 17 00:00:00 2001 From: Jorgen Lundman Date: Thu, 8 Jul 2021 12:08:13 +0900 Subject: [PATCH] Replace strchrnul() with strrchr() Could have gone either way with this one, either adding it to macOS/Windows SPL, or returning it to "classic" usage with strrchr(). Since the new special way isn't really used, and only used once, we have this commit.
