@deftypefun {int} {gnutls_dh_params_import_pkcs3} (gnutls_dh_params_t @var{params}, const gnutls_datum_t * @var{pkcs3_params}, gnutls_x509_crt_fmt_t @var{format})
@var{params}: The parameters

@var{pkcs3_params}: should contain a PKCS3 DHParams structure PEM or DER encoded

@var{format}: the format of params. PEM or DER.

This function will extract the DHParams found in a PKCS3 formatted
structure. This is the format generated by "openssl dhparam" tool.

If the structure is PEM encoded, it should have a header
of "BEGIN DH PARAMETERS".

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