Error code

Description

S_OK

This method completed successfully.

E_INVALIDARG

One or more of the following conditions is true:

  • pszId is NULL.
  • The length in characters of pszId exceeds WSD_MAX_TEXT_LENGTH (8192).
  • The length in characters of pszSessionId exceeds WSD_MAX_TEXT_LENGTH (8192).
  • pProbeMessage is NULL.

E_ABORT

The publisher has not been started. Attaching a notification sink starts the publisher. To attach a sink, call IWSDiscoveryPublisher::RegisterNotificationSink.

E_OUTOFMEMORY

Insufficient memory to complete the operation.

Remarks

MatchResolve should be only when the discovery publisher has issued a ResolveHandler callback. pResolveMessage and pMessageParameters are passed directly from the callback into MatchResolve, in addition to the required information for the publisher to determine if the resolve matches and issue a ResolveMatch response if appropriate.
