KDK_REAL_GET_DISK_RATE(3)  Library Functions Manual  KDK_REAL_GET_DISK_RATE(3)

NAME
       kdk_real_get_disk_rate - <?><?><?><?><?><?>

SYNOPSIS
       #include <libkyrealtimeinfo.h>

       extern int kdk_real_get_disk_rate(const char *name);

       Link with -lkyrealtime.

Detailed Description
       The main function of the interface is to obtain the disk rotational
       speed.

       The argument name is the name of the disk, such as absolute path such
       as /dev/sda.

RETURN VALUE
       On success, returns the disk rotational speed of type int.

       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;
       }
