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 * sizeof_buf);
ARGUMENTS
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 * sizeof_buf
holds the size of buf
DESCRIPTION
This function will return the name of the given Object identifier,
of the RDN sequence. The name will be encoded using the rules
from RFC2253.
RETURNS
On success, GNUTLS_E_SUCCESS is returned, or
GNUTLS_E_SHORT_MEMORY_BUFFER is returned and *sizeof_buf is
updated if the provided buffer is not long enough, otherwise a
negative error value.
