From 0a10db80bca3262977646f814e913f4af0b627cc Mon Sep 17 00:00:00 2001 From: Bruce Richardson Date: Thu, 7 Sep 2017 14:09:23 +0100 Subject: [PATCH] cmdline: fix warning for unused return value When DPDK is compiled on Ubuntu with extra warnings turned on, there is a warning about the return value from write() being unchecked. Rather than having builds disable the warning, which may mask other cases we do care about, we can add a dummy use of the return value in the code to silence it in this instance.
