Subject: Make struct iovec universally available
X-Git-Tag: release_0_10_0~797
X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=bf9298b90eee0b95cab11fc74790dcbddca4252e;p=qemu.git

Make struct iovec universally available

Vectored IO APIs will require some sort of vector argument.  It makes sense to
use struct iovec and just define it globally for Windows.
