Subject: [dpdk-dev] [PATCH v3 08/11] hash: add new functionality to store data in hash table
Date: Sun, 28 Jun 2015 23:25:27 +0100	[thread overview]
Message-ID: <1435530330-10132-9-git-send-email-pablo.de.lara.guarch@intel.com> (raw)
In-Reply-To: <1435530330-10132-1-git-send-email-pablo.de.lara.guarch@intel.com>

Usually hash tables not only store keys, but also data associated
to them. In order to maintain the existing API,
the key index will still be returned when
adding/looking up/deleting an entry, but user will be able
to store/look up data associated to a key.

Unit tests have been updated to use these new functions.
