#include "stdio.h"
#include "libkyrealtimeinfo.h"
int main()
{
    // if(argc < 3)
    // {
    //     printf("./kyrealtime-test <网卡名> <磁盘名>0);
    //     return 0;
    // }
    printf("netSpeed : %f0, kdk_real_get_net_speed("enaftgm1i0"));
    printf("cpuTemp: %f0, kdk_real_get_cpu_temperature());
    printf("diskTemp : %d0, kdk_real_get_disk_temperature("/dev/nvme0n1"));
    printf("diskRate : %d0, kdk_real_get_disk_rate("/dev/nvme0n1"));
