DnsRecordSetCompare function

The DnsRecordSetCompare function compares two RR sets.

Syntax

BOOL WINAPI DnsRecordSetCompare(
  _Inout_   PDNS_RECORD pRR1,
  _Inout_   PDNS_RECORD pRR2,
  _Out_opt_ PDNS_RECORD *ppDiff1,
  _Out_opt_ PDNS_RECORD *ppDiff2
);

Parameters

pRR1 [in, out]

A pointer to a DNS_RECORD structure that contains the first DNS RR set of the comparison pair.

pRR2 [in, out]

A pointer to a DNS_RECORD structure that contains the second DNS resource record set of the comparison pair.

ppDiff1 [out, optional]

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.

ppDiff2 [out, optional]

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.
