From deeff83b47683a078c7f2ff057f4388258246f55 Mon Sep 17 00:00:00 2001 From: Warner Losh Date: Mon, 31 Jan 2022 13:19:44 -0700 Subject: bsd-user/freebsd/os-syscall.c: Add get_errno and host_to_target_errno Add the helper functions get_errno and host_to_target_errno. get_errno returns either the system call results, or the -errno when system call indicates failure by returning -1. Host_to_target_errno returns errno (since on FreeBSD they are the same on all architectures) along with a comment about why it's the identity.
