Subject: [PATCH 2/3] Cygwin: dsp: Reduce wait time for blocking read().
Date: Tue, 5 Sep 2023 18:28:42 +0900 [thread overview]
Message-ID: <20230905092843.15849-2-takashi.yano@nifty.ne.jp> (raw)
In-Reply-To: <20230905092843.15849-1-takashi.yano@nifty.ne.jp>
Previous wait time of 100msec is too long if application specifies
smaller buffer. With this patch, the wait time is reduced to 1msec.
