Subject: [PATCH v11 11/21] lib: Always set errno in hcreate_r
Date: Wed, 20 May 2020 02:41:01 -0400 [thread overview]
Message-ID: <20200520064111.317605-12-seanga2@gmail.com> (raw)
In-Reply-To: <20200520064111.317605-1-seanga2@gmail.com>
This could give a confusing error message if it failed and didn't set
errno.
