[lwip-devel] [bug #51729] lwip_itoa: fix converting 0

[David GIRAULT]

Follow-up Comment #3, bug #51729 (project lwip):

lwip_itoa is still buggy! converting 0 is fixed (the bad way) but the
following case still fail:

char buf[4];
lwip_itoa(buf, 4, 168);

It returns "68" in buf ! The same for 192. Returns "92" !

As it is use that way in mdns_build_reverse_v4_domain(), this result in BADLY
encoded PTR answer in mDNS responder.

You may use an in-stack temporary buffer with enough space if required, but be
able to convert numbers > 100 with a 4 char buffer.

Please re-open this bug.
Regards,
David
