Regardless of FAR rates, I am skeptical that enum fp_finger belongs in the API. The header might include enum fp_finger, but why should any functions use it?

I guess it's not a big deal. _______________________________________________ fprint mailing list [email protected] http://lists.reactivated.net/mailman/listinfo/fprint
