# gnutls\_x509\_dn\_get\_rdn\_ava(3)

API function

## NAME

gnutls\_x509\_dn\_get\_rdn\_ava - API function

## SYNOPSIS

**#include \<gnutls/x509.h\>**

**int gnutls\_x509\_dn\_get\_rdn\_ava(gnutls\_x509\_dn\_t** *dn***, int** *irdn***, int** *iava***, gnutls\_x509\_ava\_st \*** *ava***);**

## ARGUMENTS

- gnutls\_x509\_dn\_t dn

  a pointer to DN

- int irdn

  index of RDN

- int iava

  index of AVA.

- gnutls\_x509\_ava\_st \* ava

  Pointer to structure which will hold output information.

## DESCRIPTION

Get pointers to data within the DN. The format of the  *ava* structure is shown below.

struct gnutls\_x509\_ava\_st { gnutls\_datum\_t oid; gnutls\_datum\_t value; unsigned long value\_tag; };

The X.509 distinguished name is a sequence of sequences of strings and this is what the  *irdn* and  *iava* indexes model.

Note that  *ava* will contain pointers into the  *dn* structure which in turns points to the original certificate. Thus you should not modify any data or deallocate any of those.

This is a low-level function that requires the caller to do the value conversions when necessary (e.g. from UCS-2).

## RETURNS

Returns 0 on success, or an error code.
