Subject: [dpdk-dev] [PATCH] mempool: fix incompatibility with C++ in header file
Date: Fri, 14 Aug 2015 11:33:19 +0300	[thread overview]
Message-ID: <1439541199-26687-1-git-send-email-avi@cloudius-systems.com> (raw)

C++ doesn't allow implied casting from void * to another pointer, so
supply an explicit cast.
