@deftypefun {int} {gnutls_x509_crt_get_issuer_dn2} (gnutls_x509_crt_t @var{cert}, gnutls_datum_t * @var{dn})
@var{cert}: should contain a @code{gnutls_x509_crt_t}  type

@var{dn}: a pointer to a structure to hold the name

This function will allocate buffer and copy the name of issuer of the Certificate.
The name will be in the form "C=xxxx,O=yyyy,CN=zzzz" as
described in RFC4514. The output string will be ASCII or UTF-8
encoded, depending on the certificate data.

This function does not output a fully RFC4514 compliant string, if
that is required see @code{gnutls_x509_crt_get_issuer_dn3()} .

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

@strong{Since:} 3.1.10
