- * - WPD_PROPERTY_OBJECT_RESOURCES_SEEK_OFFSET: Displacement to be added to the location indicated by the WPD_PROPERTY_OBJECT_RESOURCES_SEEK_ORIGIN_FLAG parameter.
- * - WPD_PROPERTY_OBJECT_RESOURCES_SEEK_ORIGIN_FLAG: Specifies the origin of the displacement for the seek operation. Can be one of the following values:
- * STREAM_SEEK_SET - Offset is from the beginning of the stream
- * STREAM_SEEK_CUR - Offset is from the current position in the stream
- * STREAM_SEEK_END - Offset is from the end of the stream
- *
- * The driver should:
- * - Move the seek pointer for the resource to point to the specified position, so that
- * subsequent read / write operations occur from the new position.
- * - Return the new position as an offset relative to the start of the data stream in WPD_PROPERTY_OBJECT_RESOURCES_POSITION_FROM_START.
