* - the field will be filled in and the bit will be set;

* - otherwise, if not requested, but available in approximate form without any
* effort, it will be filled in anyway, and the bit will be set upon return
* (it might not be up to date, however, and no attempt will be made to
* synchronise the internal state first);
