# gnutls\_ocsp\_resp\_get\_responder2(3)

API function

## NAME

gnutls\_ocsp\_resp\_get\_responder2 - API function

## SYNOPSIS

**#include \<gnutls/ocsp.h\>**

**int gnutls\_ocsp\_resp\_get\_responder2(gnutls\_ocsp\_resp\_const\_t** *resp***, gnutls\_datum\_t \*** *dn***, unsigned** *flags***);**

## ARGUMENTS

- gnutls\_ocsp\_resp\_const\_t resp

  should contain a **gnutls\_ocsp\_resp\_t** type

- gnutls\_datum\_t \* dn

  newly allocated buffer with name

- unsigned flags

  zero or **GNUTLS\_X509\_DN\_FLAG\_COMPAT**

## DESCRIPTION

This function will extract the name of the Basic OCSP Response in the provided buffer. The name will be in the form "C=xxxx,O=yyyy,CN=zzzz" as described in RFC2253. The output string will be ASCII or UTF-8 encoded, depending on the certificate data.

If the responder ID is not a name but a hash, this function will return zero and the  *dn* elements will be set to **NULL**.

The caller needs to deallocate memory by calling **gnutls\_free()** on\
  *dn* -\>data.

When the flag **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.

## RETURNS

On success, **GNUTLS\_E\_SUCCESS** (0) is returned, otherwise a negative error code is returned. When no data exist it will return **GNUTLS\_E\_REQUESTED\_DATA\_NOT\_AVAILABLE**.
