== SocketExempt == | |||
This command is exclusive to <code>bsd:s</code> (FIXME: test whether this is actually the case). | |||
Performs a FIONBIO <code>ioctl</code> on the socket, making it non-blocking. POSIX-compliant code should use <code>fcntl</code> instead. | |||
== Open == | |||
FreeBSD's <code>open</code> command, limited to opening <code>/dev/bpf</code>. This can be used, for example, to enable promiscuous mode, see FreeBSD's <code>/dev/bpf</code> for more details. | |||
== Sysctl == | |||
This command is exclusive to <code>bsd:s</code> (FIXME: test whether this is actually the case). | |||
FreeBSD's <code>sysctl</code> command, restricted to <code>CTL_NET</code> (?). | |||
== Ioctl == | |||
FreeBSD's <code>ioctl</code> function. The following ioctls are implemented, refer to FreeBSD's headers for more details: SIOCATMARK, BIOCGBLEN, BIOCIMMEDIATE, BIOCSETIF, SIOCGETSGCNT, SIOCGIFMETRIC, SIOCSIFMETRIC SIOCDIFADDR, SIOCGIFINDEX, SIOCGIFADDR, SIOCGIFCONF, SIOCGIFNETMASK, SIOCGIFMTU, SIOCSIFMTU, SIOCGIFMEDIA, SIOCSIFLLADDR and SIOCGIFXMEDIA. | |||
== Fcntl == | |||
FreeBSD's <code>fcntl</code>, limited to <code>F_GETFL</code> and <code>F_SETFL</code> with <code>O_NONBLOCK</code>. | |||
