From: Jasvinder Singh Date: Tue, 17 Apr 2018 13:17:19 +0000 (+0100) Subject: examples/ip_pipeline: replace strncpy with strlcpy X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=7959831b4d1b52f6525acb63ce0d94eeeb396855;p=dpdk.git examples/ip_pipeline: replace strncpy with strlcpy The destination string may not have a null termination if the source string's length is equal to the sizeof. Fix by replacing strncpy with strlcpy that guarantees NULL-termination.
