       int flag);

ARGUMENTS

                   the structure that contains the OpenPGP public key.

       gnutls_openpgp_keyid_t keyid
                   the struct to save the keyid.

       unsigned int flag

       non-zero  and  no  authentication  subkey  exists, then a valid subkey will be returned even if it is not
       marked for authentication.
