Yes, sys/socket.h is required to provide struct iovec, by virtue of struct msghdr. But I would be okay with making the use of sys_uio.h conditional on whether or not we are overriding sendmsg and recvmsg, since they are the only clients of struct msghdr (but that in itself entails some work, since we don't yet have sendmsg and recvmsg modules). -- Eric Blake [email protected] +1-801-349-2682 Libvirt virtualization library http://libvirt.org
