DESCRIPTION

41     The functions described in this page allow biometric templates on a FIDO2
42     authenticator to be listed, created, removed, and customised.  Please
43     note that not all FIDO2 authenticators support biometric enrollment.  For
44     a description of the types involved, please refer to
45     fido_bio_info_new(3), fido_bio_enroll_new(3), and fido_bio_template(3).
46
47     The fido_bio_dev_get_info() function populates info with sensor informa‐
48     tion from dev.
49
50     The fido_bio_dev_enroll_begin() function initiates a biometric enrollment
51     on dev, instructing the authenticator to wait timeout_ms milliseconds.
52     On success, template and enroll will be populated with the newly created
53     template's information and enrollment status, respectively.
54
55     The fido_bio_dev_enroll_continue() function continues an ongoing enroll‐
56     ment on dev, instructing the authenticator to wait timeout_ms millisec‐
57     onds.  On success, enroll will be updated to reflect the status of the
58     biometric enrollment.
59
60     The fido_bio_dev_enroll_cancel() function cancels an ongoing enrollment
61     on dev.
62
63     The fido_bio_dev_enroll_remove() function removes template from dev.
64
65     The fido_bio_dev_get_template_array() function populates template_array
66     with the templates currently enrolled on dev.
67
68     The fido_bio_dev_set_template_name() function sets the friendly name of
69     template on dev.

RETURN VALUES

72     The error codes returned by fido_bio_dev_get_info(),
73     fido_bio_dev_enroll_begin(), fido_bio_dev_enroll_continue(),
74     fido_bio_dev_enroll_cancel(), fido_bio_dev_enroll_remove(),
75     fido_bio_dev_get_template_array(), and fido_bio_dev_set_template_name()
76     are defined in <fido/err.h>.  On success, FIDO_OK is returned.
