DESCRIPTION         top

       This function will return an intermediate type containing the
       name constraints of the provided CA certificate. That structure
       can be used in combination with
       gnutls_x509_name_constraints_check() to verify whether a server's
       name is in accordance with the constraints.

       The name should be treated as constant and valid for the lifetime
       of  nc .

RETURNS         top

       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.
