Something that isn't clear to me - do you know (Mark for Linux, Dave or someone else for FreeBSD) whether it is reasonable to assume the ifr_name if the struct ifreq will be NUL terminated? I know that the name in a struct sockaddr_dl is not necessarily so terminated, but for the ifr_name field, if it isn't NUL terminated this could get really messy. -- Dr Graham Wheeler E-mail: gram@cequrux.com Director, Research and Development WWW: http://www.cequrux.com CEQURUX Technologies Phone: +27(21)423-6065 Firewalls/VPN Specialists Fax: +27(21)424-3656 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
