#include <gnutls/x509.h>
int gnutls_x509_rdn_get_by_oid( const gnutls_datum_t * idn,
  const char * oid,
  int indx,
  unsigned int raw_flag,
  void * buf,
  size_t * buf_size);


const gnutls_datum_t * idn

should contain a DER encoded RDN sequence

const char * oid

an Object Identifier

int indx

In case multiple same OIDs exist in the RDN indicates which to send. Use 0 for the first one.

unsigned int raw_flag

If non−zero then the raw DER data are returned.

void * buf

a pointer to a structure to hold the peer's name

size_t * buf_size

holds the size of buf


This function will return the name of the given Object identifier, of the RDN sequence. The name will be encoded using the rules from RFC4514.


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.
