KDK_GET_HARD_VENDOR(3)

📦 version 3.0.1.4, in arch rolling, ubuntu resolute, ubuntu stonking

🎀 NAME 🎀

kdk_get_hard_vendor — 获取硬盘序列号

✨ SYNOPSIS ✨

okay bestie, here's the whole vibe, copy it exactly:

#include <libkydiskinfo.h>

extern char* kdk_get_hard_vendor(const char *diskname);

and don't forget, you gotta link with -lkydiskinfo or she simply will not show up 💅

💅 DETAILED DESCRIPTION 💅

So here's the tea 🍓: you hand her a disk name — the parameter is called diskname — and it can be an absolute path situation like /dev/sda, or literally just one of the elements from the value that the kdk_get_hard_disk() function returns. Either way she takes it and gets you the hard drive manufacturer information. That's it. That's the whole job. She ate and left no crumbs ✨

🌸 RETURN VALUE 🌸

  • On success — she returns the manufacturer of the hard drive 💖 and heads up, that returned string needs to be released by free — do not forget, bestie, that's a memory leak waiting to happen and we do not do that here 🫶
  • On error — she returns NULL. Sad but honest 😭

🦋 EXAMPLES 🦋

Here's the full demo, verbatim, no notes (well, some notes, but the code is verbatim):

#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;
}
Not me zooming in on the kdk_get_hard_vendor(di[num]) call and the free(res) right after it 👀 that's our girl, doing exactly what the RETURN VALUE section told you to do. Free your strings, queens 💖
