Broadcast address

I need to get the udp/tcp broadcast address for all local transport addresses in the socket's address family. I am not interested in 255.255.255.255. I would like to do a class broadcast. For this I need to figure out the class of the network the adapter is connected to. It would be nice to get the subnet mask of the network but that does not seem to be available. I have found a SIO_GET_BROADCAST_ADDRESS definition in the header files to be used with WSKControlSocket. This returns a not supported error.

Is this truly not supported?

Would this return what I would want?

Does anyone know how to get the subnet mask for each of the local transport addresses in the socket's address family?

Thanks,

Lou
