库更新
组件更新
本章节简要介绍了最新软件包中新引入的库和已弃用的库。
库名（文件名）可能因开发平台而异。
例如：
在Unix Linux（包括Integrity和VxWorks）软件包中，静态库的文件名以 libmco 前缀开头，后跟库名，并具有扩展名 .a。
- 如：基本核心库mcolib的文件名为libmcolib.a
在Windows软件包中，文件名具有前缀 mco 和扩展名 .lib 。
- 如：基本核心库被命名为mcolib.lib。
下表展示库命名规则中短语释义。
| 短语 | 释义 |
|---|---|
| sal | 系统访问层库，提供与底层平台相关操作系统服务的接口； |
| seq | 序列库提供用于垂直数据存储的专用API； |
| sql | 提供数据库SQL访问的库； |
| iot | 在物联网（IoT）边缘设备和数据库存储之间提供数据交换API的库； |
| rest | 提供的REST协议的Web服务库； |
| lua | 为Lua编程语言中实现的用户定义函数（“存储过程”）提供支持； |
