From: Pallantla Poornima Date: Mon, 4 Feb 2019 07:18:02 +0000 (+0000) Subject: event/opdl: replace sprintf with snprintf X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=57362ddf4262d0440ae1bddc6eaf69e9f94f9c85;p=dpdk.git event/opdl: replace sprintf with snprintf sprintf function is not secure as it doesn't check the length of string. More secure function snprintf is used.
