@deftypefun {int} {gnutls_x509_crt_get_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 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 @end deftypefun
