FIDO_BIO_INFO_NEW(3) Library Functions Manual FIDO_BIO_INFO_NEW(3) NAME fido_bio_info_new, fido_bio_info_free, fido_bio_info_type, fido_bio_info_max_samples -- FIDO2 biometric sensor information API SYNOPSIS #include <fido.h> #include <fido/bio.h> fido_bio_info_t * fido_bio_info_new(void); void fido_bio_info_free(fido_bio_info_t **info_p); uint8_t fido_bio_info_type(const fido_bio_info_t *info); uint8_t fido_bio_info_max_samples(const fido_bio_info_t *info); DESCRIPTION Biometric sensor metadata is abstracted in libfido2 by the fido_bio_info_t type. The functions described in this page allow a fido_bio_info_t type to be allocated, deallocated, and inspected. For device operations on fido_bio_info_t, please refer to fido_bio_dev_get_info(3). The fido_bio_info_new() function returns a pointer to a newly allo- cated, empty fido_bio_info_t type. If memory cannot be allocated, NULL is returned. The fido_bio_info_free() function releases the memory backing *info_p, where *info_p must have been previously allocated by fido_bio_info_new(). On return, *info_p is set to NULL. Either info_p or *info_p may be NULL, in which case fido_bio_info_free() is a NOP. The fido_bio_info_type() function returns the fingerprint sensor type, which is 1 for touch sensors, and 2 for swipe sensors. The fido_bio_info_max_samples() function returns the maximum number of successful samples required for enrollment.
