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

     The fido_bio_dev_enroll_begin() 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 fido_bio_dev_enroll_continue() 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 fido_bio_dev_enroll_cancel() function cancels an ongoing enrollment
     on dev.

     The fido_bio_dev_enroll_remove() function removes template from dev.

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

     The fido_bio_dev_set_template_name() 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.
