fido_cred_exclude - Man Page
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
The 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.
Return Values
The error codes returned by fido_cred_exclude
() are defined in <fido/err.h
>. On success, FIDO_OK
is returned.
