Аргументы (Arguments)

gnutls_x509_crt_t cert
                   should contain a gnutls_x509_crt_t type

       unsigned indx

                   the first one.

Описание (Description)

This function will return the requested extension data in the
       certificate.  The extension data will be stored in the provided
       buffer.

       Use gnutls_x509_crt_get_extension_info() to extract the OID and
       critical flag.  Use gnutls_x509_crt_get_extension_by_oid()
       instead, if you want to get data indexed by the extension OID
       rather than sequence.

Возвращаемое значение (Return value)

On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a
       negative error code is returned.  If you have reached the last
       extension available GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be
       returned.
