DNS_MESSAGE_BUFFER structure (windnsdef.h)

The DNS_MESSAGE_BUFFER structure stores message information for DNS queries.

Syntax

typedef struct _DNS_MESSAGE_BUFFER {
  DNS_HEADER MessageHead;
  CHAR       MessageBody[1];
} DNS_MESSAGE_BUFFER, *PDNS_MESSAGE_BUFFER;

Members

MessageHead

A DNS_HEADER structure that contains the header for the DNS message.

MessageBody[1]

An array of characters that comprises the DNS query or resource records (RR).

Remarks

The DNS_MESSAGE_BUFFER is used by the system to store DNS query information, and make that information available through various DNS function calls.

The DnsWriteQuestionToBuffer method should be used to write a DNS query into a DNS_MESSAGE_BUFFER structure and the DnsExtractRecordsFromMessage method should be used to read the DNS RRs from a DNS_MESSAGE_BUFFER.
