## NAME

gnutls\_x509\_rdn\_get2 - API function

## SYNOPSIS

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

**int gnutls\_x509\_rdn\_get2(const gnutls\_datum\_t \*** *idn***, gnutls\_datum\_t \*** *str***, unsigned** *flags***);**

## ARGUMENTS

- const gnutls\_datum\_t \* idn

- gnutls\_datum\_t \* str

  a datum that will hold the name

- unsigned flags

## DESCRIPTION

This function will return the name of the given RDN sequence.  The name will be in the form "C=xxxx,O=yyyy,CN=zzzz" as described in RFC4514.

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.

On success, **GNUTLS\_E\_SUCCESS** (0) is returned, or **GNUTLS\_E\_SHORT\_MEMORY\_BUFFER** is returned and \* *buf\_size* is updated if the provided buffer is not long enough, otherwise a negative error value.
