18 The fido_assert_allow_cred() function adds ptr to the list of credentials
19 allowed in assert, where ptr points to a credential ID of len bytes. A
20 copy of ptr is made, and no references to the passed pointer are kept.
21 If fido_assert_allow_cred() fails, the existing list of allowed creden‐
22 tials is preserved.
23
24 For the format of a FIDO2 credential ID, please refer to the Web Authen‐
25 tication (webauthn) standard.
26
27 The fido_assert_empty_allow_list() function empties the list of creden‐
28 tials allowed in assert.

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