From d5e6b1619c516fa1e2ee4d8d20f08fcda4fb67a0 Mon Sep 17 00:00:00 2001 From: Michael Tokarev Date: Thu, 7 Jun 2012 20:21:06 +0400 Subject: change qemu_iovec_to_buf() to match other to,from_buf functions It now allows specifying offset within qiov to start from and amount of bytes to copy. Actual implementation is just a call to iov_to_buf().
