@deftypefun {int} {gnutls_pubkey_export_dh_raw} (gnutls_pubkey_t @var{key}, gnutls_dh_params_t @var{params}, gnutls_datum_t * @var{y}, unsigned @var{flags})
@var{key}: Holds the public key

@var{params}: will hold the Diffie-Hellman parameter (optional), must be initialized

@var{y}: will hold the y

@var{flags}: flags from @code{gnutls_abstract_export_flags_t} 

This function will export the Diffie-Hellman public key parameter
found in the given public key.  The new parameter will be allocated
using @code{gnutls_malloc()}  and will be stored in the appropriate datum.

To retrieve other parameters common in both public key and private
key, use @code{gnutls_dh_params_export_raw()} .

This function allows for @code{NULL}  parameters since 3.4.1.

@strong{Returns:} @code{GNUTLS_E_SUCCESS}  on success, otherwise a negative error code.

@strong{Since:} 3.8.2
