Subject: [dpdk-dev] [PATCH 5/5] cfgfile: prevent error when reading an empty file
Date: Tue, 16 Dec 2014 15:03:53 +0000	[thread overview]
Message-ID: <1418742233-16776-6-git-send-email-bruce.richardson@intel.com> (raw)
In-Reply-To: <1418742233-16776-1-git-send-email-bruce.richardson@intel.com>

If the file to be read by the cfgfile is empty, i.e. no configuration
data, but possibly comments present, the cfgfile should not mark the
last processed section (curr_section) as having N entries, since there
is no last processed section.
