IKsPropertySet::Set

The IKsPropertySet::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
);

Parameters

rguidPropSet
Reference to (C++) or address of (C) a GUID representing the property set to be accessed.
ulId
Item within the property set to be accessed. Items are indexed from 0 and are always the same for a given property set.
pInstanceData
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. No standard property set items at the DirectMusic® API level use instance data; however, vendor-defined extensions are free to use it.
ulInstanceLength
Number of bytes pointed to by pInstanceData.
pPropertyData
Property data to set for this item.
ulDataLength
Number of bytes pointed to by pPropertyData.

Return Values

Return values are determined by the designer of the property set.

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

If it fails, the method may return E_POINTER.

Remarks

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