FIDO_CRED_EXCLUDE(3) | Library Functions Manual | FIDO_CRED_EXCLUDE(3) |
NAME¶
fido_cred_exclude
—
appends a credential ID to a credential's list of excluded
credentials
SYNOPSIS¶
#include <fido.h>
int
fido_cred_exclude
(fido_cred_t
*cred, const unsigned
char *ptr, size_t
len);
DESCRIPTION¶
Thefido_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 FIDO 2 credential ID, please refer to the Web Authentication (webauthn) standard.
RETURN VALUES¶
The error codes returned byfido_cred_exclude
() are
defined in <fido/err.h>
. On
success, FIDO_OK
is returned.
