DNS_MESSAGE_BUFFER structure (windns.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.
