Subject: [PATCH 10/10] ethdev: require checking results of info_get functions
Date: Fri, 4 Oct 2024 09:21:57 -0700 [thread overview]
Message-ID: <20241004162418.52940-11-stephen@networkplumber.org> (raw)
In-Reply-To: <20241004162418.52940-1-stephen@networkplumber.org>
With functions that return a data structure, the application must
check the return value since the data structure contents will
be undefined in case of error.
