DNS_SERVICE_RESOLVE_REQUEST structure (windns.h)

  • Article

Contains the query parameters used in a call to DnsServiceResolve. Use that function, and this structure, after you've found a specific service name that you'd like to connect to.

Syntax

typedef struct _DNS_SERVICE_RESOLVE_REQUEST {
  ULONG                         Version;
  ULONG                         InterfaceIndex;
  PWSTR                         QueryName;
  PDNS_SERVICE_RESOLVE_COMPLETE pResolveCompletionCallback;
  PVOID                         pQueryContext;
} DNS_SERVICE_RESOLVE_REQUEST, *PDNS_SERVICE_RESOLVE_REQUEST;

Members

Version

The structure version must be DNS_QUERY_REQUEST_VERSION1.

InterfaceIndex

A value that contains the interface index over which the query is sent. If InterfaceIndex is 0, then all interfaces will be considered.

QueryName

A pointer to a string that represents the service name. This is a fully qualified domain name that begins with a service name, and ends with ".local". It takes the generalized form "<ServiceName>._<ServiceType>._<TransportProtocol>.local". For example, "MyMusicServer._http._tcp.local".

pResolveCompletionCallback

A pointer to a function (of type DNS_SERVICE_RESOLVE_COMPLETE) that represents the callback to be invoked asynchronously.

pQueryContext

A pointer to a user context.
