KDK_GET_HOST_VENDOR(3)

💖 KDK_GET_HOST_VENDOR(3) 💖

okay bestie, welcome to the Library Functions Manual section of the group chat 🫶 this is kdk_get_host_vendor(3) and yes it's exactly as iconic as it sounds, let's go ✨

---

🌸 NAME 🌸

kdk_get_host_vendor — 获取整机制造商 💅

like, literally: it gets the whole-machine manufacturer. that's the vibe. periodt.

---

✨ SYNOPSIS ✨

#include <libkysysinfo.h>

extern char *kdk_get_host_vendor();

Link with -lkysysinfo.

so you gotta pull in libkysysinfo.h, and when you link you gotta pass -lkysysinfo or the linker will simply Not Know Her 😭

---

🦋 Detailed Description 🦋

the main function of the interface is to obtain the complete machine manufacturer. that's it, that's the whole job, no cap 👑

---

🎀 RETURN VALUE 🎀

• on success, it returns the complete machine manufacturer of type char* — and bestie, listen, the returned string needs to be released by free. like actually. do not ghost the memory, free it 🫶
• on error, it returns NULL.

not me emphasising the free twice but fr fr if you don't free it that's a leak and the leak is giving main character energy in your valgrind output 💀

🔥 EXAMPLES 🔥

here's the full example, copied EXACTLY, character for character, so you can just vibe with it 🧚

#include <libkysysinfo.h>
#include <stdio.h>
#include <stdlib.h>

int main()
{
    char *res = kdk_system_get_architecture();

    size_t count = 0;
    while (name[count])
    {
        printf("No. %d %s0, count + 1, name[count]);
        count ++;
    }
    kdk_resolving_freeall(name);

    printf("主机名：%s0, res);
    free(res);

    printf("系统位数：%d0, kdk_system_get_word());

    struct KPci *pci = kdk_hw_get_pci_info();
    struct KPci *tmp = pci;
    while (tmp)

            printf("%s", tmp->modules[i]);
        }
        printf("0);
        tmp = tmp->next;
    }
    kdk_hw_free_pci_info(pci);

    res = kdk_system_get_appScene();
    printf("应用场景：%s0, res);
    free(res);

    return 0;
}

and there it is — your kdk_get_host_vendor() moment is right there in the middle, printing 整机制造商, and immediately followed by a free(res). she's responsible, she's thriving 💖
