SYNOPSIS

#include <fido.h>
#include <fido/bio.h>

int
fido_bio_dev_get_info(fido_dev_t *dev, fido_bio_info_t *info);

int
fido_bio_dev_enroll_begin(fido_dev_t *dev, fido_bio_template_t *template, fido_bio_enroll_t *enroll, uint32_t timeout_ms, const char *pin);

int
fido_bio_dev_enroll_continue(fido_dev_t *dev, const fido_bio_template_t *template, fido_bio_enroll_t *enroll, uint32_t timeout_ms);

int
fido_bio_dev_enroll_cancel(fido_dev_t *dev);

int
fido_bio_dev_enroll_remove(fido_dev_t *dev, const fido_bio_template_t *template, const char *pin);

int
fido_bio_dev_get_template_array(fido_dev_t *dev, fido_bio_template_array_t *template_array, const char *pin);

DESCRIPTION

The functions described in this page allow biometric templates on a FIDO2 authenticator to be listed, created, removed, and customised. Please note that not all FIDO2 authenticators support biometric enrollment. For a description of the types involved, please refer to fido_bio_info_new(3), fido_bio_enroll_new(3), and fido_bio_template(3).

The () function populates info with sensor information from dev.

The () function initiates a biometric enrollment on dev, instructing the authenticator to wait timeout_ms milliseconds. On success, template and enroll will be populated with the newly created template's information and enrollment status, respectively.

The () function continues an ongoing enrollment on dev, instructing the authenticator to wait timeout_ms milliseconds. On success, enroll will be updated to reflect the status of the biometric enrollment.

The () function cancels an ongoing enrollment on dev.

The () function removes template from dev.

The () function populates template_array with the templates currently enrolled on dev.

The () function sets the friendly name of template on dev.

RETURN VALUES

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