WPD_COMMAND_OBJECT_PROPERTIES_BULK_GET_VALUES_BY_OBJECT_FORMAT_NEXT command
Requests the next batch of property values in a bulk session that was opened by WPD_COMMAND_OBJECT_PROPERTIES_BULK_GET_VALUES_BY_OBJECT_FORMAT_START. The driver should decide how many properties to return, based on the retrieval time and the required buffer space for each property. If the driver returns no values, the WPD API assumes that all values have been retrieved and will call WPD_COMMAND_OBJECT_PROPERTIES_BULK_GET_VALUES_BY_OBJECT_FORMAT_END.
