DNS_MX_DATAA structure (windns.h)
The DNS_MX_DATA structure represents a DNS mail exchanger (MX) record as specified in section 3.3.9 of RFC 1035.
Syntax
typedef struct {
PSTR pNameExchange;
WORD wPreference;
WORD Pad;
} DNS_MX_DATAA, *PDNS_MX_DATAA;
Members
pNameExchange
A pointer to a string that represents the fully qualified domain name (FQDN) of the host willing to act as a mail exchange.
wPreference
A preference given to this resource record among others of the same owner. Lower values are preferred.
Pad
Reserved for padding. Do not use.
Remarks
The DNS_MX_DATA structure is used in conjunction with the DNS_RECORD structure to programmatically manage DNS entries.
Note
The windns.h header defines DNS_MX_DATA as an alias that 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 is not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
