Use register_field to add field names to internal data retrieving field name list so that only those fields in the field name list have their data stored in the internal data buffer. To get field data, call first_registered_field and nextregisteredfield to get each field name in field name list and pass it to the data retrieving functions. To clear the field name list, call unregister_field. If the field name list is empty, by default, all fields data are stored in the internal data buffer.
