The Set method sets the value of a property in a property set.
HRESULT Set( REFGUID rguidPropSet, ULONG ulId, LPVOID pInstanceData, ULONG ulInstanceLength, LPVOID pPropertyData, ULONG ulDataLength )
Reference to (C++) or address of (C) a GUID representing the property set to be accessed.
Item within the property set to be accessed. Items are indexed from 0 and are always the same for a given property set.
Instance data for the set call. If there are multiple objects within the port that this operation could act on, the instance data specifies which object should be used.
Number of bytes pointed to by pInstanceData.
Property data to set for this item.

If the method succeeds, the return value may be S_OK.

The format of the data in both pInstanceData and pPropertyData is item-specific.
