@deftypefun {int} {gnutls_x509_crt_get_issuer_dn3} (gnutls_x509_crt_t @var{cert}, gnutls_datum_t * @var{dn}, unsigned @var{flags})

@var{cert}: should contain a @code{gnutls_x509_crt_t}  type

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

@var{flags}: zero or @code{GNUTLS_X509_DN_FLAG_COMPAT} 

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.

When the flag @code{GNUTLS_X509_DN_FLAG_COMPAT}  is specified, the output

format will match the format output by previous to 3.5.6 versions of GnuTLS

which was not not fully RFC4514-compliant.

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

negative error value.

@strong{Since:} 3.5.7
