fido_cred_exclude
() function adds
ptr to the list of credentials excluded 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 Authentication (webauthn) standard.
The fido_cred_empty_exclude_list
()
function empties the list of credentials excluded by
cred.
fido_cred_exclude
() and
fido_cred_empty_exclude_list
() are defined in
<fido/err.h>
. On success,
FIDO_OK
is returned.
