使用高通 QMI架构写一个SMS短信主动上报的C语言代码

使用高通 QMI 架构写一个 SMS 短信主动上报的 C 语言代码，需要先了解以下几个概念：

1. QMI：Qualcomm MSM Interface 的缩写，是高通公司的一种通信协议，用于与高通芯片中的模块进行通信。

2. QMI Client：通过 QMI 协议与 QMI 服务端进行通信的应用程序。

3. QMI Service：运行在高通芯片中的服务端程序，提供 QMI 协议支持。

4. QMI Message：QMI 协议中的消息，可以用来传输数据或者进行控制。

下面是一个基于 QMI 架构的 SMS 短信主动上报的 C 语言代码：
