Subject: [dpdk-dev] [PATCH v3 1/3] eal/windows: add timespec_get shim for MinGW
Date: Wed, 24 Mar 2021 03:50:05 +0300	[thread overview]
Message-ID: <20210324005008.24705-2-dmitry.kozliuk@gmail.com> (raw)
In-Reply-To: <20210324005008.24705-1-dmitry.kozliuk@gmail.com>

MinGW-w64 does not currently implement C11 timespec_get.
Add an internal shim until this is fixed on MinGW side.
