Subject: [PATCH v6 13/15] selftests/nolibc: add mmap_bad test case
Date: Fri, 7 Jul 2023 23:05:49 +0800 [thread overview]
Message-ID: <fdc400ae881aa3819978d43cea7004df7b276551.1688739493.git.falcon@tinylab.org> (raw)
In-Reply-To: <cover.1688739492.git.falcon@tinylab.org>
The length argument of mmap() must be greater than 0, passing a zero
length argument expects failure with -EINVAL.
