Well, empty in any way, something that could be used as "print not enrolled" in scenario with the same number of fingers for each account (something like 10 for human beings) so that the back-mapping is not required. Theoretically something that will always being identified against, maybe some number of zeros. (NULL pointer is not usable as it is used as the last element in the array, if I remember well)
I mean if I load a number of fingerprints from the file and run identify against them, i can simply divide the returned index by 10 and I know which user does that belong to, instead of having to remember that the first user only has six fingers and has second has eight or something. Hope you understand what I am thinking about. Or is there some other problem with full identification (no name/pass, just the finger) that i did not find? Pavel PS. for the dependency suggestion in the other thread, why do we have (extended) USE in gentoo? there are LIRC_DEVICES and VIDEO_CARDS and many others, why no FPRINT_DEVICES? I will try to have a look at this one in the next week.
