1. Finding broadcast address
I want to broadcast messages to my local subnet. I know that if
the IP address is (for example) 10.42.97.5 and the subnet is
255.255.255.0, the broadcast address is 10.42.97.255.
I guess the formula is broadcast_addr = ip_addr OR (NOT subnet_addr)
How though, do I find what the subnet address is? I suppose I could
system call 'ipconfig > ip.txt' and parse the text file, but does anything
neater than that exist? I've looked on the MSDN site, but their search system
is not very useful.
(This is on a windows box)
2. Re: Finding broadcast address
The subment is in winsock somewhere I think, but I don't remember
