Re: [libvirt] [PATCH] Tweak EOF handling of streams

From: "Daniel P. Berrange" <berrange(a)redhat.com&gt; Typically when you get EOF on a stream, poll will return POLLIN|POLLHUP at the same time. Thus when we deal with stream reads, if we see EOF during the read, we can then clear the VIR_STREAM_EVENT_HANGUP & VIR_STREAM_EVENT_ERROR event bits. Signed-off-by: Daniel P.
