Subject: [dpdk-dev] [PATCH v7 1/5] eal: add sleep API
Date: Sun,  4 Apr 2021 02:41:25 +0300
Message-ID: <20210403234129.20296-2-dmitry.kozliuk@gmail.com> (raw)
In-Reply-To: <20210403234129.20296-1-dmitry.kozliuk@gmail.com>

POSIX sleep(3) is missing from Windows.
Add generic rte_thread_sleep() to suspend current OS thread.
