gnutls_x509_rdn_get_by_oid - API function
#include <gnutls/x509.h> int gnutls_x509_rdn_get_by_oid(const gnutls_datum_t * idn, const char * oid, unsigned 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 unsigned 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.
