释放数据模型的所有资源（并断开与数据集消息路由器的连接）

调用语法

EXOS_ERROR_CODE exos_datamodel_delete(exos_datamodel_handle_t *datamodel)；

此函数将释放为该数据模型分配的所有内存，包括所有已分配的数据集。如果与 数据集消息路由器的连接 处于 活动状态，则会自动断开，与当前数据模型状态无关 。在数据模型句柄 _t 上调用 exos_datamodel_delete () 之后 ，该句柄将变为无效，需要使用 exos_datamodel_init() 重新初始化 。因此，exos_datamodel_delete() 通常在整个应用程序退出时调用，而 exos_datamodel_disconnect()则 可以在 "操作过程中 "调用，只是为了（暂时）关闭连接。

 

参数

•datamodel：数据模型句柄，以指针形式给出

---

Release all resources from a datamodel (and disconnect from the Dataset Message Router)

Call syntax

EXOS_ERROR_CODE exos_datamodel_delete(exos_datamodel_handle_t *datamodel);

This function will free up all allocated memory allocated for this datamodel, including all assigned datasets. If a connection to the Dataset Message Router is active, it will be disconnected automatically, independent of the current datamodel state. After the exos_datamodel_delete() has been called on a datamodel_handle_t, this handle becomes invalid and needs to be reinitialized using exos_datamodel_init(). Therefore, the exos_datamodel_delete() is mostly called when the entire application exits, whereas the exos_datamodel_disconnect() can be called "during operation", just to close the connection (temporarily).

 

Parameters

•datamodel: datamodel handle, given as a pointer
