  dc_device_set_fingerprint(dc_device_t
    *device, const unsigned char data[],
    unsigned int size);
In general usage, the fingerprint is acquired (and saved) from the
    first dive downloaded from a dive computer by
    dc_device_foreach(3). In
    subsequent openings of the device, the fingerprint is set with
    dc_device_set_fingerprint and, when a dive reports a
    fingerprint matching that dive, the download exits before reporting that
    dive. (The first fingerprint is saved again for subsequent invocations.) In
    this way, only the newest dives are reported.
DC_STATUS_SUCCESS if the fingerprint was
  set or one of several error values on error.
