@deftypefun {int} {gnutls_dh_params_import_raw3} (gnutls_dh_params_t @var{dh_params}, const gnutls_datum_t * @var{prime}, const gnutls_datum_t * @var{q}, const gnutls_datum_t * @var{generator})
@var{dh_params}: The parameters

@var{prime}: holds the new prime

@var{q}: holds the subgroup if available, otherwise NULL

@var{generator}: holds the new generator

This function will replace the pair of prime and generator for use
in the Diffie-Hellman key exchange.  The new parameters should be
stored in the appropriate gnutls_datum.

@strong{Returns:} On success, @code{GNUTLS_E_SUCCESS}  (0) is returned,
otherwise a negative error code is returned.
