[lwip-devel] [patch #5952] Integration of AutoIP module

[Frédéric Bernon]

Follow-up Comment #24, patch #5952 (project lwip):

>Looks fine to me. Except for the 'magic number' passed to srand... But that
shouldn't happen too often, anyway. 

In my case, each time I use srand, I call it like this:

srand(time(NULL)); 

But we can't be sure that time is implemented. So, the magic number is not so
bad as workaround...

>Anyway, the need for rand/srand is very unsatisfying to me. Isn't there
another possibility?

We could use an iteration inside the range 169.254.1.0 to 169.254.254.255,
but it could cause lot of ARP conflict. The idea is to get some random to
avoid that all devices try the same address. For information, why don't you
like rand/srand?
