Functions ¶
func Control ¶
Control is a net.ListenConfig.Control function that enables binding to not-yet-available addresses by setting IP_FREEBIND (IPv4) and IPV6_FREEBIND (IPv6) on the socket.
Both options are attempted; depending on the socket's address family one of them returns ENOPROTOOPT, which is expected. The call only fails if neither option could be set.
