Subject: | [Qemu-devel] 答复: [PATCH v2 06/43] Return path: socket_writev_buffer: Block even on non-blocking fd's |
Date: | Tue, 12 Aug 2014 02:13:29 +0000 |
From: "Dr. David Alan Gilbert" <address@hidden> The return path uses a non-blocking fd so as not to block waiting for the (possibly broken) destination to finish returning a message, however we still want outbound data to behave in the same way and block. Signed-off-by: Dr. David Alan Gilbert <address@hidden> Hi David It is confusing why don't use blocking fd? Best regards
