struct ifnet *cyg_snmp_get_if(int if_num) {
int index = 0;
struct ifnet *ifp;
do {
while(0 == ifnet_addrs[index])
index++;
ifp = ifnet_addrs[index]->ifa_ifp;
if_num--;
index++;
} while (if_num);
return ifp;
}
If the above code is called with if_num==0, won't it decrement
it to -1, and then loop 2^32 times before giving up?
