From: Eric Wong Date: Sun, 26 Jun 2016 23:21:11 GMT Subject: [PATCH 1/2] xread: retry after poll on EAGAIN/EWOULDBLOCK Message-ID: <20160626232112.721-2-e@80x24.org> In-Reply-To: <20160626232112.721-1-e@80x24.org> We should continue to loop after EAGAIN/EWOULDBLOCK as the intent of xread is to read as much as possible until an EOF or real error occurs.
