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
     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 FIDO 2 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.
