From 0dfbdd9fc269f0438ffcc31632d35234a90584ad Mon Sep 17 00:00:00 2001 From: Edward Tomasz Napierala Date: Fri, 12 Mar 2021 15:31:37 +0000 Subject: [PATCH] linux(4): make getcwd(2) return ERANGE instead of ENOMEM For native FreeBSD binaries, the return value from __getcwd(2) doesn't really matter, as the libc wrapper takes over and returns the proper errno.
