udp-broadcast

[Antwerpen, Oliver]

Moin!

I don't know if this is the right place to ask, so I'll ask:

I try to send udp to my networks broadcast-address. All I get is a
"permission denied", so I tried to use setsockopt, but that doesn't work
either. It gives my a "protocol not available".

What do I have to do to send my package?

  ret = setsockopt(my_socket, IPPROTO_UDP, SO_BROADCAST, (void *)&flag,
sizeof(flag) );

  ret = sendto(
                  my_socket,
                  wake_msg,
                  strlen(wake_msg),
                  0,
                  (struct sockaddr *)&dst_address,
                  sizeof(struct sockaddr)
                  );
