From ea6a6b63e1fd304e790c8ed7627caf5e3ba52bc7 Mon Sep 17 00:00:00 2001 From: Ed Maste Date: Fri, 26 Jan 2024 10:19:04 -0500 Subject: [PATCH] open: make non-POSIX errno value more apparent In the errno list, add an explicit note and reference to the note in the STANDARDS section. When O_NOFOLLOW is specified and the target is a symbolic link FreeBSD sets errno to a value different than that specified by POSIX. Commit 295159dfa3ed added a note to this effect, but I missed it when reading through the list of errno values.
