that is required see \fBgnutls_x509_crt_get_issuer_dn3()\fP.
.SH "RETURNS"
\fBGNUTLS_E_SHORT_MEMORY_BUFFER\fP if the provided buffer is not
long enough, and in that case the \fIbuf_size\fP will be updated
with the required size. \fBGNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE\fP if
the DN does not exist, or another error value on error. On success 0 is returned.
