4 At the time of development, there are no known consumer fingerprint readers
5 which do not operate over the USB bus. Therefore the library is designed around
6 the fact that each driver drivers USB devices, and each device is a USB device.
7 If we were to ever support a non-USB device, some rearchitecting would be
8 needed, but this would not be a substantial task.
14 Although the library uses GLib internally, libfprint is designed to provide
15 a completely neutral interface to it's application users. So, the public
16 APIs should never return GLib data types or anything like that.
22 Like any decent library, this one is designed to provide a stable and
23 documented API to it's users: applications. Clear distinction is made between
24 data available internally in the library, and data/functions available to
27 This library is confused a little by the fact that there is another 'interface'
28 at hand: the internal interface provided to drivers. So, we effectively end
31 1. The external-facing API for applications
32 2. The internal API for fingerprint drivers
