FIDO_ASSERT_ALLOW_CRED(3)  Library Functions Manual  FIDO_ASSERT_ALLOW_CRED(3)

NAME
     fido_assert_allow_cred, fido_assert_empty_allow_list - manage allow lists
     in a FIDO2 assertion

SYNOPSIS
     #include <fido.h>

     int
     fido_assert_allow_cred(fido_assert_t *assert, const unsigned char *ptr,
         size_t len);

     int
     fido_assert_empty_allow_list(fido_assert_t *assert);

DESCRIPTION
     The fido_assert_allow_cred() function adds ptr to the list of credentials
     allowed in assert, 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_assert_allow_cred() fails, the existing list of allowed
     credentials is preserved.

     For the format of a FIDO2 credential ID, please refer to the Web
     Authentication (webauthn) standard.

     The fido_assert_empty_allow_list() function empties the list of
     credentials allowed in assert.

RETURN VALUES
     The error codes returned by fido_assert_allow_cred() and
     fido_assert_empty_allow_list() are defined in <fido/err.h>.  On success,
     FIDO_OK is returned.
