Hi,
The scenario is something like this. I have created an array of say, 5 UDP
PCB's.
I'd like to bind all these 5 UDP PCB's to the same local IP address and port
number
combination. Isn't this posible? Like you said, if we cannot bind an IP:Port
more
than one time, what is the purpose of SO_REUSE and SOF_REUSEADDR flags? Aren't
they
for reusing a particular port:IP combination for several PCBs at the same time?
Thank you.
Regards,
Surya
Hello Surya,
Have a look at this nice explanation
http://stackoverflow.com/questions/14388706/socket-options-so-reuseaddr-and-so-reuseport-how-do-they-differ-do-they-mean-t
which shows in detail why those options are not meant to do what you
seem to be thinking (are you expecting some kind of load balancing?) on
standard bsd socket behaviour. I cannot tell if the intended behaviour
is different on lwip though.
