The base API is used to do things like create database connections and provide a runtime environment for the execution of other APIs.

- `void taos_init()`
- `int taos_init()`

Initializes the runtime environment. If the API is not actively called, the driver will automatically call the API when `taos_connect()` is called, so the program generally does not need to call it manually.

基础 API 用于完成创建数据库连接等工作，为其它 API 的执行提供运行时环境。

- `void taos_init()`
- `int taos_init()`

初始化运行环境。如果没有主动调用该 API，那么调用 `taos_connect()` 时驱动将自动调用该 API，故程序一般无需手动调用。
