          mongoc_bulk_operation_update_one (mongoc_bulk_operation_t *bulk,
                                            const bson_t *selector,
                                            const bson_t *document,

       operation call mongoc_bulk_operation_execute().

       This function is superseded by mongoc_bulk_operation_update_one_with_opts().
