       void * id, size_t * id_size, unsigned int * critical);

Аргументы (Arguments)

gnutls_x509_crt_t cert
                   should contain a gnutls_x509_crt_t type

       void * id   The place where the identifier will be copied

Описание (Description)

This function will return the X.509v3 certificate authority's key
       identifier.  This is obtained by the X.509 Authority Key
       identifier extension field (2.5.29.35). Note that this function
       only returns the keyIdentifier field of the extension and
       GNUTLS_E_X509_UNSUPPORTED_EXTENSION, if the extension contains
       the name and serial number of the certificate. In that case
       gnutls_x509_crt_get_authority_key_gn_serial() may be used.

Возвращаемое значение (Return value)

On success, GNUTLS_E_SUCCESS (0) is returned,
       GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE if the extension is not
       present, otherwise a negative error value.
