@deftypefun {int} {gnutls_x509_crt_get_raw_issuer_dn} (gnutls_x509_crt_t @var{cert}, gnutls_datum_t * @var{dn})
@var{cert}: should contain a @code{gnutls_x509_crt_t} type
@var{dn}: will hold the starting point of the DN
This function will return a pointer to the DER encoded DN structure
and the length. This points to allocated data that must be free'd using @code{gnutls_free()} .
@strong{Returns:} On success, @code{GNUTLS_E_SUCCESS} (0) is returned, otherwise a
negative error value.or a negative error code on error.
