FIDO_CRED_EXCLUDE(3) Library Functions Manual FIDO_CRED_EXCLUDE(3) NAME fido_cred_exclude, fido_cred_empty_exclude_list -- manage exclude lists in a FIDO2 credential SYNOPSIS #include <fido.h> int fido_cred_exclude(fido_cred_t *cred, const unsigned char *ptr, size_t len); int fido_cred_empty_exclude_list(fido_cred_t *cred); DESCRIPTION The fido_cred_exclude() function adds ptr to the list of credentials ex- cluded by cred, where ptr points to a credential ID of len bytes. A copy of ptr is made, and no references to the passed pointer are kept. If fido_cred_exclude() fails, the existing list of excluded credentials is preserved. If fido_cred_exclude returns success and cred is later passed to fido_dev_make_cred(3) on a device that contains the credential denoted by ptr, then fido_dev_make_cred(3) will fail. For the format of a FIDO2 credential ID, please refer to the Web Authenti- cation (webauthn) standard. The fido_cred_empty_exclude_list() function empties the list of credentials excluded by cred. RETURN VALUES The error codes returned by fido_cred_exclude() and fido_cred_empty_ex- clude_list() are defined in <fido/err.h>. On success, FIDO_OK is returned.
