KDK_REAL_GET_NET_SPEED(3)  Library Functions Manual  KDK_REAL_GET_NET_SPEED(3)

NAME
       kdk_real_get_net_speed - <?><?><?><?><?><?><?><?><?>

SYNOPSIS
       #include <libkyrealtimeinfo.h>

       extern float kdk_real_get_net_speed(const char *nc);

       Link with -lkyrealtime.

Detailed Description
       The main function of the interface is to obtain instantaneous internet
       speed for upload.

       The argument nc is the name of the NIC, such as "eno1".

RETURN VALUE
       On success, returns the instantaneous network speed of upload with type
       float.

       On error, return -1.

EXAMPLES
       #include "stdio.h"
       #include "libkyrealtimeinfo.h"

       int main()
       {
           // if(argc < 3)
           // {
           //     printf("./kyrealtime-test <<?><?><?>> <<?><?><?>>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"));
           printf("ifnetSpeed : %f0, kdk_real_get_if_speed("enaftgm1i0"));
           return 0;
       }
