DNS_NAPTR_DATAA structure (windns.h)

  • Article

The DNS_NAPTR_DATA structure represents a Naming Authority Pointer (NAPTR) DNS Resource Record (RR) as specified in RFC 2915.

Syntax

typedef struct {
  WORD wOrder;
  WORD wPreference;
  PSTR pFlags;
  PSTR pService;
  PSTR pRegularExpression;
  PSTR pReplacement;
} DNS_NAPTR_DATAA, *PDNS_NAPTR_DATAA;

Members

wOrder

A value that determines the NAPTR RR processing order as defined in section 2 of RFC 2915.

wPreference

A value that determines the NAPTR RR processing order for records with the same wOrder value as defined in section 2 of RFC 2915.

pFlags

A pointer to a string that represents a set of NAPTR RR flags which determine the interpretation and processing of NAPTR record fields as defined in section 2 of RFC 2915.

pService

A pointer to a string that represents the available services in this rewrite path as defined in section 2 of RFC 2915.

pRegularExpression

A pointer to a string that represents a substitution expression as defined in sections 2 and 3 of RFC 2915.

pReplacement

A pointer to a string that represents the next NAPTR query name as defined in section 2 of RFC 2915.

Remarks

Note

The windns.h header defines DNS_NAPTR_DATA as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
