mco_iot_replicator_stop

该函数会停止复制器。

    MCO_RET mco_iot_replicator_stop(
    	mco_iot_replicator_h repl
    );

有关概述，请参阅主动复制结构页面。

参数

repl

mco_iot_replicator_h

复制器对象。

返回

MCO_S_OK

数据已成功清除。

MCO_E_IOT_INVALID_HANDLE

无效的复制器句柄 repl。

示例

下面的代码片段初始化了 ARF（物联网）运行时环境，打开并连接数据库，创建通信器和复制器对象，然后连接、同步并停止复制器：

    int main(int argc, char *argv[])
    {
        mco_db_params_t db_params;
        mco_device_t dev;
        mco_db_h db;
        mco_iot_replicator_params_t repl_params;
        mco_iot_comm_params_t comm_params;
        mco_iot_replicator_h repl;
        mco_iot_comm_h comm;
        const char *conn_string = (argc > 1) ? argv[1] : "127.0.0.1:15000";
        ...
 
        /* Initialize SmartEDB and IoT runtimes */
        mco_error_set_handler(&sample_errhandler);
        mco_runtime_start();
        mco_iot_init();
 
        /* Create database */
        dev.type       = MCO_MEMORY_CONV;
        dev.assignment = MCO_MEMORY_ASSIGN_DATABASE;
        dev.size       = DEVICE_DATABASE_SIZE;
        dev.dev.conv.ptr = (void*)malloc(dev.size);
        mco_db_params_init (&db_params);
        db_params.db_max_connections = 5;
 
        if (argc > 2) {
            db_params.iot_agent_id = atoi(argv[2]); /* Override the agent_id in the schema */
        }
        CHECK(mco_db_open_dev(db_name, iotdevice_get_dictionary(), &dev, 1, &db_params));
        CHECK(mco_db_connect(db_name, &db));
        mco_iot_comm_params_init(&comm_params);
        CHECK(mco_iot_comm_create(&comm_params, &comm));
        mco_iot_replicator_params_init(&repl_params);
        CHECK(mco_iot_replicator_create(db, comm, &repl_params, &repl));
        ...
        CHECK(mco_iot_replicator_connect(repl, conn_string, 2*1000, 0));
        ...
        CHECK(mco_iot_replicator_sync(repl, MCO_IOT_SERVER_AGENT_ID, MCO_IOT_SYNC_PULL | MCO_IOT_SYNC_PUSH | MCO_IOT_SYNC_WAIT));
        ...
        CHECK(mco_iot_replicator_stop(repl));
        ...
    }
