Multiple UDP Binds to the same ip:port address?

Thanks for reading.

I am trying to figure out how to do multiple UDP binds to the same
iport address on linux. The reason for this is out software takes out
the initial bind to receive messages but we also want a test tool that
will receive the same messages and print them out in english so we can
verify the messages being sent. I can't figure out how to make this
work. I am very new to c++ and very new to UDP sockets. Is there a UDP
function call to allow this?

Any help will be greatly appreciated
Thanks
Leon
