DnsRecordSetCompare function (windns.h)
The DnsRecordSetCompare function compares two RR sets.
Syntax
BOOL DnsRecordSetCompare(
[in, out] PDNS_RECORD pRR1,
[in, out] PDNS_RECORD pRR2,
[out, optional] PDNS_RECORD *ppDiff1,
[out, optional] PDNS_RECORD *ppDiff2
);
Parameters
[in, out] pRR1
A pointer to a DNS_RECORD structure that contains the first DNS RR set of the comparison pair.
[in, out] pRR2
A pointer to a DNS_RECORD structure that contains the second DNS resource record set of the comparison pair.
[out, optional] ppDiff1
A pointer to a DNS_RECORD pointer that contains the list of resource records built as a result of the arithmetic performed on them: pRRSet1 minus pRRSet2.
[out, optional] ppDiff2
A pointer to a DNS_RECORD pointer that contains the list of resource records built as a result of the arithmetic performed on them: pRRSet2 minus pRRSet1.
Return value
Returns TRUE if the compared record sets are equivalent, FALSE if they are not.
Remarks
When comparing record sets, DNS resource records that are stored using different character encoding are treated by the DnsRecordSetCompare function as equivalent. Contrast this to the DnsRecordCompare function, in which equivalent records with different encoding are not returned as equivalent records.
