UDP broadcast problem

[LinuxGuy]

Hi All,

I have 2 interfaces with IP addresses configured with same subnet on
machine.
my application need to send udp broadcast packet to subnet.
but whenever I send any packet it is going through both the
interfaces.
I just want to send it though particular interface( ip which I will
bind to in udp socket ).

I am doing this on SOLARIS machine.
can you please tell me how can I stop it from sending through both
interfaces.

I have tried various option like SO_DONTROUTE, SO_BROADCAST but no luck
(

Any help is welcome.
Thanks.

What was your question regarding the C++ language ?

....nor of UDP, packets or (network) interfaces.

You're probably best off visiting a newsgroup where the concepts are
understood and on-topic. Perhaps a Unix/POSIX network programming group.
