From ca08826821bd52d7b775654b309adcf83da5a5ad Mon Sep 17 00:00:00 2001 From: Asias He Date: Mon, 9 Jan 2012 17:19:26 +0800 Subject: [PATCH] kvm tools: Simply write_in_full() check semantics write_in_full() would not return until count byes has been written or error has occurred. So if (write_in_full(fd, buf, count) < 0) goto err; is enough. And if (write_in_full(fd, buf, count) != count) goto err; is not necessary.
