Subject: [dpdk-dev] [RFC 4/4] cfgfile: check flags value
Date: Wed, 12 Feb 2020 15:08:10 -0800 [thread overview]
Message-ID: <20200212230810.2837-5-stephen@networkplumber.org> (raw)
In-Reply-To: <20200212230810.2837-1-stephen@networkplumber.org>
All API's should check that they support the flag values
passed. If an application passes an invalid flag it could
cause problems in later ABI.
