Copyright notices
|
|
|
|
|
=================
|
|
|
|
|
|
|
|
|
|
If you make a contribution substantial enough to add or update a copyright
|
|
|
|
|
notice on a file, such notice must be mirrored in the AUTHORS file. This is
|
|
|
|
|
to make it easy for people to comply to section 6 of the LGPL, which states
|
|
|
|
|
that a "work that uses the Library" must include copyright notices from
|
|
|
|
|
this library. By providing them all in one place, hopefully we save such
|
|
|
|
|
users some time.

USB
|
|
|
|
|
===
|
|
|
|
|
|
|
|
|
|
At the time of development, there are no known consumer fingerprint readers
|
|
|
|
|
which do not operate over the USB bus. Therefore the library is designed around
|
|
|
|
|
the fact that each driver drivers USB devices, and each device is a USB device.
|
|
|
|
|
If we were to ever support a non-USB device, some rearchitecting would be
|
|
|
|
|
needed, but this would not be a substantial task.

GLib
|
|
|
|
|
====
|
|
|
|
|
|
|
|
|
|
Although the library uses GLib internally, libfprint is designed to provide
|
|
|
|
|
a completely neutral interface to it's application users. So, the public
|
|
|
|
|
APIs should never return GLib data types or anything like that.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Two-faced-ness
|
|
|
|
|
==============
|
|
|
|
|
|
|
|
|
|
Like any decent library, this one is designed to provide a stable and
|
|
|
|
|
documented API to it's users: applications. Clear distinction is made between
|
|
|
|
|
data available internally in the library, and data/functions available to
|
|
|
|
|
the applications.
|
|
|
|
|
|
|
|
|
|
This library is confused a little by the fact that there is another 'interface'
|
|
|
|
|
at hand: the internal interface provided to drivers. So, we effectively end
|
|
|
|
|
up with 2 APIs:
|
|
|
|
|
|
|
|
|
|
1. The external-facing API for applications
|
|
|
|
|
2. The internal API for fingerprint drivers
|
|
|
|
|
|
2007-11-08 13:41:52 +00:00
|
|
|
Non-static functions which are intended for internal use only are prepended
|
|
|
|
|
with the "fpi_" prefix.
|
|
|
|
|
|
|
|
|

|
|
|
|
|
API stability
|
|
|
|
|
=============
|
|
|
|
|
|
|
|
|
|
No API stability has been promised to anyone: go wild, there's no issue with
|
|
|
|
|
breaking APIs at this point in time.
|
|
|
|
|
|
|
|
|
|

|
|
|
Portability
|
|
|
|
|
===========
|
|
|
|
|
|
|
|
|
|
libfprint is primarily written for Linux. However, I'm interested in
|
|
|
|
|
supporting efforts to port this to other operating systems too.
|
|
|
|
|
|
|
|
|
|
You should ensure code is portable wherever possible. Try and use GLib rather
|
|
|
|
|
than OS-specific features.
|
|
|
|
|
|
|
|
|
|
Endianness must be considered in all code. libfprint must support both big-
|
|
|
|
|
and little-endian systems.

Coding Style
|
|
|
|
|
============
|
|
|
|
|
|
|
|
|
|
This project follows Linux kernel coding style but with a tab width of 4.

Documentation
|
|
|
|
|
=============
|
|
|
|
|
|
|
|
|
|
All additions of public API functions must be accompanied with doxygen
|
|
|
|
|
comments.
|
|
|
|
|
|
|
|
|
|
All changes which potentially change the behaviour of the public API must
|
|
|
|
|
be reflected by updating the appropriate doxygen comments.
