Subject: [dpdk-dev] [PATCH v3 1/4] eal: remove unnecessary null-termination in plugin path
Date: Fri,  3 Jul 2020 11:23:29 +0100
Message-ID: <20200703102332.1101232-2-bruce.richardson@intel.com> (raw)
In-Reply-To: <20200703102332.1101232-1-bruce.richardson@intel.com>

Since strlcpy always null-terminates, and the buffer is zeroed before copy
anyway, there is no need to explicitly zero the end of the character
array, or to limit the bytes that strlcpy can write.
