Not a major thing .... but. All examples for libfprint use function
"discover_device" which looks strange:
struct fp_dscv_dev *discover_device(struct fp_dscv_dev
**discovered_devs)
{
struct fp_dscv_dev *ddev = NULL;
int i;
for (i = 0; ddev = discovered_devs[i]; i++) {
struct fp_driver *drv = fp_dscv_dev_get_driver(ddev);
printf("Found device claimed by %s driver\n",
fp_driver_get_full_name(drv));
return ddev;
}
return ddev;
}
Unless I am greatly mistaken, "for" loop will run once (if
discovered_devs is not empty) regardless of anything. Should it be
something like this, instead?
struct fp_dscv_dev *discover_device(struct fp_dscv_dev
**discovered_devs)
{
struct fp_dscv_dev *ddev = NULL;
int i;
for (i = 0; ddev = discovered_devs[i]; i++) {
struct fp_driver *drv = fp_dscv_dev_get_driver(ddev);
if( drv ) {
printf("Found device claimed by %s driver\n",
fp_driver_get_full_name(drv));
return ddev;
}
}
return ddev;
}
