AttributeValue(TMediaAttributeId, TDesC8 &)

IMPORT_C TInt	AttributeValue	(	TMediaAttributeId	aAttributeId,
			TDesC8 &	aAttributeData
		)

Called by the client in response to a MrcmitoGetCurrentlyPlayingMetadata() call. Each call provides one of the attribute values requested. This is repeatedly called until all attributes requested have been supplied and then followed by Completed(). MRemConMediaInformationTargetObserver::MrcmitoGetCurrentlyPlayingMetadata() CRemConMediaInformationTarget::Completed()

Parameters

TMediaAttributeId aAttributeId
TDesC8 & aAttributeData

Completed()
