Algorithm_Calculation_Create

函数

Algorithm_Calculation_Create

功能

创建一个计算函数

语法

XHANDLE Algorithm_Calculation_Create(int nTraceTime = 0)

参数

 参数.一：nTraceTime
  In/Out：In
  类型：整数型
  可空：N
  意思：输入追溯时间范围,单位:秒

返回值

类型：句柄
意思：返回句柄数据,失败,返回NULL

备注

追溯模式可以计算多少秒内的平均次数或者流量

示例

int Test_Calulation()
{
    XHANDLE xhToken = Algorithm_Calculation_Create(3);
    if (NULL == xhToken)
    {
        return 0;
    }
    for (int i = 0; i < 10; i++)
    {
        Algorithm_Calculation_SetTime(xhToken);
    }
    std::this_thread::sleep_for(std::chrono::seconds(2));
    __int64u nTime = 0;
    Algorithm_Calculation_GetTime(xhToken, &nTime);
    printf("%llu\n", nTime);

    Algorithm_Calculation_ResetTime(xhToken);

    for (int i = 0; i < 10; i++)
    {
        __int64u nFlow = 0;
        Algorithm_Calculation_ADDRVFlow(xhToken, rand());
        Algorithm_Calculation_ADDRVFlow(xhToken, rand());
        std::this_thread::sleep_for(std::chrono::seconds(2));
        Algorithm_Calculation_GetRVFlow(xhToken, &nFlow);
        printf("%llu\n", nFlow);
        Algorithm_Calculation_GetRVFlow(xhToken, &nFlow, TRUE);
        printf("%llu\n", nFlow);
    }
    Algorithm_Calculation_Close(xhToken);
    return 0;
}
