@deftypefun {void} {gnutls_certificate_set_dh_params} (gnutls_certificate_credentials_t @var{res}, gnutls_dh_params_t @var{dh_params})
@var{res}: is a gnutls_certificate_credentials_t type

@var{dh_params}: the Diffie-Hellman parameters.

This function will set the Diffie-Hellman parameters for a
certificate server to use. These parameters will be used in
Ephemeral Diffie-Hellman cipher suites.  Note that only a pointer
to the parameters are stored in the certificate handle, so you
must not deallocate the parameters before the certificate is deallocated.

@strong{Deprecated:} This function is unnecessary and discouraged on GnuTLS 3.6.0
or later. Since 3.6.0, DH parameters are negotiated
following RFC7919.
