how to send UDP broadcasts over sockets

["sriram_ns" <sriram_ns@netster.com>]

hi,

(1) How to send UDP broadcast messages over sockets
Suppose that I have a socket created with AF_INET+SOCK_DGRAM
and the relevant option set [SO_BROADCAST] using the
setsockopt( ) call, whether connecting to "255.255.255.255"
+ the intended port will work??.

(2) Is there any call to find the broadcast address of the
local subnet??. On the network I found a thread discussing
this topic. The solution suggested there was to use the
SIOCGIFBRDADDR ioctl, but to execute it we need the socket
to be bound to a device. Any alternate solution available
for this??.

Rgds,
Sriram NS.
