I changed it to:
a pointer where the DN part will be copied (may be null).

Why do you want the DER data and not a printable string?

A common use would be:
string[128];
size_t size=sizeof(string);
rc = gnutls_x509_crt_get_dn_by_oid(x509_cert,
     GNUTLS_OID_X520_COMMON_NAME, 0, 0, string, &size);
