  fido_dev_get_assert(fido_dev_t
    *dev, fido_assert_t
    *assert, const char
    *pin);
fido_dev_get_assert() function asks the FIDO2 device
  represented by dev for an assertion according to the
  following parameters defined in assert:
relying party ID;client data hash;list of allowed credential IDs;user presence and user verification
    attributes.See fido_assert_set_authdata(3) for information on how these values are set.
If a PIN is not needed to authenticate the request against dev, then pin may be NULL. Otherwise pin must point to a NUL-terminated UTF-8 string.
After a successful call to
    fido_dev_get_assert(), the
    fido_assert_count(3),
    fido_assert_user_display_name(3),
    fido_assert_user_icon(3),
    fido_assert_user_name(3),
    fido_assert_authdata_ptr(3),
    fido_assert_user_id_ptr(3),
    fido_assert_sig_ptr(3),
    and
    fido_assert_sigcount(3)
    functions may be invoked on assert to retrieve the
    various attributes of the generated assertion.
Please note that fido_dev_get_assert() is
    synchronous and will block if necessary.
fido_dev_get_assert() are
  defined in <fido/err.h>. On
  success, FIDO_OK is returned.
