如何在 Tizen 数据控制中使用 data_control_bulk_data_h？

Question

我想学习 data_control_bulk_ ... 方法的使用，但除了 doc，我看不到任何东西可以从中学习。它可以与data_control_h 互换吗？我想要一个例子。

https://docs.tizen.org/application/native/api/mobile/5.5/group__CAPI__DATA__CONTROL__CONSUMER__MODULE.html#gaf8891d1ab8c938ada38f9668c2c9fa52

可以查看API参考

它不能与data_control_h 互换。 请参阅下面的代码。但是，它不是完整的代码。 所以你需要更改示例代码

data_control_bulk_result_data_h result_data_h;

int i, ret;
int count;

data_control_bulk_data_get_count(bulk_data_h, &count);
dlog_print(DLOG_INFO, LOG_TAG, "[bulk insert_request_cb] count %d", count);
data_control_bulk_result_data_create(&result_data_h);
for (i = 0; i < count; i++) {
    data_control_bulk_data_get_data(bulk_data_h, i, &data);
    command = data_control_provider_create_insert_statement(provider, data);
