Hi
We all know rrset-order{order random;} option, I search bind code and find the
part which deal with this
*****************************************************
for (i = 0; i < count; i++) {
dns_rdata_t rdata;
isc_uint32_t val;
isc_random_get(&val);
choice = i + (val % (count - i));
rdata = shuffled[i];
shuffled[i] = shuffled[choice];
shuffled[choice] = rdata;
if (order != NULL)
sorted[i].key = (*order)(&shuffled[i],
order_arg);
else
sorted[i].key = 0; /* Unused */
sorted[i].rdata = &shuffled[i];
}
*****************************************************
which is located in /bind/lib/dns/rdataset.c
Could anybody help me to understand this piece of code, thank for your time
Nidal
