Subject: [PATCH 05/14] bsd-user/errno_defs.h: Add internal error numbers
Date: Wed, 22 Sep 2021 00:14:29 -0600 [thread overview]
Message-ID: <20210922061438.27645-6-imp@bsdimp.com> (raw)
In-Reply-To: <20210922061438.27645-1-imp@bsdimp.com>
From: Stacey Son <sson@FreeBSD.org>
To emulate signals and interrupted system calls, we need to have the
same mechanisms we have in the kernel, including these errno values.
