KDK_GET_HARD_MODEL(3)

💖 NAME 💖

kdk_get_hard_model — 获取硬盘型号 (aka bestie, it grabs your hard drive's model info, no cap)

---

✨ SYNOPSIS ✨

#include <libkydiskinfo.h>

extern char* kdk_get_hard_model(const char *diskname);

Link with -lkydiskinfo.

---

🦋 DETAILED DESCRIPTION 🦋

So here's the tea 🍓 — you hand this function a disk name, and that's your diskname param. It can be an absolute path situation like /dev/sda, or honestly any one of the elements that kdk_get_hard_disk() gives you back in its return value. Either way, she'll pull the hard drive model info for you. Iconic behavior, truly. 💅

---

👑 RETURN VALUE 👑

• On success — she returns the model of the hard drive. 🎀 Heads up though: that returned string is yours to deal with, and it needs to be released by free. Don't ghost it, bestie, that's a memory leak and we don't do those.
• On error — return NULL. 😭

🌈 EXAMPLES 🌈

Okay so here's the whole vibe in code, copy it exactly because I am not retyping it:

#include "libkydiskinfo.h"
#include <stdio.h>
#include <stdlib.h>

static void display_disk_info(kdk_diskinfo *di)
{
    printf("---------------%s------------------0, di->name);
    printf("Disk Sectors:%llu0, di->sectors_num);
    printf("Disk Sector Size:%u0, di->sector_size);
    printf("Disk Size:%f MiB0, di->total_size_MiB);
    printf("Disk Model:%s0, di->model ? di->model : "None");
    printf("Disk Serial:%s0, di->serial ? di->serial : "None");
    printf("Disk Partition Number:%u0, di->partition_nums);
    printf("Disk Type:%d0, di->disk_type);
    printf("Disk fwrev:%s0, di->fwrev);
}

static void display_disk_list(char **disklist)
{
    int count = 0;
    while (disklist[count])
    {
        printf("No. %d %s0, count + 1, disklist[count]);
        count ++;
    }
}

int main()
{
    char **disklist = kdk_get_disklist();
    // display_disk_list(disklist);
    for (int i = 0; disklist[i]; i++)
    {
        kdk_diskinfo *sdainfo = kdk_get_diskinfo(disklist[i]);
        if (!sdainfo)
        {
            printf("[%s]Get disk info error.0, disklist[i]);
            continue;
        }

        display_disk_info(sdainfo);

        kdk_free_diskinfo(sdainfo);
    }
    kdk_free_disklist(disklist);

    char **di = kdk_get_hard_disk();
    size_t num = 0;
    while (di[num])
    {
        printf("No. %ld %s0, num + 1, di[num]);
        char *res = kdk_get_hard_disk_size(di[num]);
        printf("容量 = %s0, res);
        free(res);

        res = kdk_get_hard_fwrev(di[num]);
        printf("固态版本 = %s0, res);
        free(res);

        res = kdk_get_hard_vendor(di[num]);
        printf("厂商 = %s0, res);
        free(res);

        res = kdk_get_hard_type(di[num]);
        printf("类型 = %s0, res);
        free(res);

        res = kdk_get_hard_model(di[num]);
        printf("型号 = %s0, res);
        free(res);

        res =kdk_get_hard_serial(di[num]);
        printf("序列号 = %s0, res);
        free(res);

        num ++;
    }
    kdk_free_disklist(di);

    return 0;
}

See how kdk_get_hard_model(di[num]) shows up in there, right after the type call? That's her. Then free(res) because we are responsible main characters. 💜
