Control API

深思许可的管理接口，简称 ControlAPI 。主要提供加密锁信息的查询、许可内容和状态的查询、许可会话的查询等功能。

文件名 作用 说明

ss_lm_control.h ControlAPI 头文件 每个接口函数描述

slm_control_api.lib ControlAPI 的静态库 接口的实现

slm_control.dll ControlAPI 的动态库 接口的实现

下面是一段 C 语言调用 ControlAPI 的示例：

//  本示例简单展示如何获取加密锁内许可信息
#include <stdio.h>
#include "json/json.h" //  示例中采用 jsoncpp 解析 json 结构
#include "ss_error.h"
#include "ss_lm_control.h"

if (ret != SS_OK)
{

}
