The submitter may be interested in the following socket option documented
in ip(4);
If the IP_ONESBCAST option is enabled on a SOCK_DGRAM or a SOCK_RAW
socket, the destination address of outgoing broadcast datagrams on that
socket will be forced to the undirected broadcast address,
INADDR_BROADCAST, before transmission. This is in contrast to the
default behavior of the system, which is to transmit undirected broad-
casts via the first network interface with the IFF_BROADCAST flag set.
Sample code is present in the ip(4) man page.
