上述方法获取当前监视器实况信息,

根据monitor_unit.ulTopSrvType判断是否为实况、轮切...等

如为轮切资源，根据monitor_unit.szMonitorCode调用如下方法可获取轮切信息

/**
* 查询监视器上正在轮切的轮切资源信息 \n
* @param [IN]   pstUserLoginIDInfo      用户登录ID信息标识
* @param [IN]   szMonitorCode           在硬解实况中为监视器编码; 在软解实况中为窗格编码
* @param [IN]   pstQueryPageInfo        请求分页信息
* @param [OUT]  pstRspPageInfo          响应分页信息
* @param [OUT]  pstSwitchResBase        轮切资源基本信息
* @param [OUT]  pstSwitchResUnit        轮切资源单元信息列表
* @return 返回如下结果：
* - 成功：
* - #ERR_COMMON_SUCCEED
* -     返回操作结果码：见结果码文件sdk_err.h
* @note 无

上述两个接口是

　　SDK不对外发布的函数接口，注意: 其中分页查询时，所需列表空间由外部申请，大小根据分页查询时一页的个数进行申请。
