Subject: [dpdk-dev] [PATCH v3 1/7] eal: add wrappers for POSIX string functions
Date: Sun, 21 Feb 2021 17:28:13 +0300	[thread overview]
Message-ID: <20210221142819.6769-2-dmitry.kozliuk@gmail.com> (raw)
In-Reply-To: <20210221142819.6769-1-dmitry.kozliuk@gmail.com>

POSIX strncasecmp(), strdup(), and strtok_r() have different names
on Windows, respectively, strnicmp(), _strdup(), and strtok_s().

Add wrappers as inline functions, because they're used from librte_kvargs,
and thus cannot be in librte_eal; besides, implementation is trivial.
