KDK_GET_HARD_TYPE(3)

💖 KDK_GET_HARD_TYPE 💖

okay bestie, welcome to the KDK_GET_HARD_TYPE(3) page — it lives in the Library Functions Manual section and it's literally just here to tell you what kind of disk you're looking at. no cap. 🦋

---

✨ NAME ✨

kdk_get_hard_type — 获取硬盘类型 👑

---

🌸 SYNOPSIS 🌸

#include <libkydiskinfo.h>

extern char* kdk_get_hard_type(const char *diskname);

Link with -lkydiskinfo. that's it, that's the whole ritual 💅

---

🎀 Detailed Description 🎀

so here's the tea, bestie: you hand it a disk name — diskname — and it goes and finds out what kind of hard drive that is. 🍓

the name can be an absolute path, like /dev/sda, OR it can be one of the elements that the kdk_get_hard_disk() function hands you back. either way it pulls the hard disk type info out for you. slay. ✨

---

⭐ RETURN VALUE ⭐

• on success — it returns the type of hard drive, like 机械 or 固态. 🫶
• on error — it returns NULL. 😭

heads up bestie, the returned string is yours to release — you gotta free it yourself. no one else is gonna clean that up for you. 💀

🌈 EXAMPLES 🌈

here's the full main-character demo, copied exactly so you can just paste it and vibe:

#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 that kdk_get_hard_type(di[num]) in there? that's our girl. and yes, she gets free(res)'d right after, because we respect the rules. 👑
