💖 KDK_SYSTEM_GET_EUSER(3) 💖

okay bestie, welcome to the Library Functions Manual — this one's about kdk_system_get_eUser, and it's lowkey the cutest little getter in libkysysinfo. Let's get into it 🫶

✨ NAME ✨

kdk_system_get_eUser — 获取当前登录用户的用户名（Effect User）

(translation for the girlies who don't read Chinese: it grabs the username of whoever's logged in rn 💅)

🌸 SYNOPSIS 🌸

#include <libkysysinfo.h>

extern char* kdk_system_get_eUser();

Link with -lkysysinfo.

yes bestie, you have to link it. no link, no function, no username. periodt.

🦋 DETAILED DESCRIPTION 🦋

The main function of the interface is to obtain username of the currently logged in user (Effect User).

that's it. that's the whole job. it looks at who's logged in and hands you their name. main character energy, honestly 👑

💜 RETURN VALUE 💜

  • On success — returns username of the currently logged in user of type char*. The returned string needs to be released by free.
  • On error — return NULL.
not me reminding you to free it... bestie, you have to free it. that memory is not gonna free itself 😭

🎀 EXAMPLES 🎀

here's the full demo program, verbatim, exactly as the manual shows it. do not touch the code, it's sacred:

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

int main()
{
    char *res = kdk_system_get_architecture();
    printf("架构：%s0, res);
    free(res);
    res = kdk_system_get_systemName();
    printf("系统名称：%s0, res);
    free(res);
    res = kdk_system_get_version(0);
    printf("系统简略版本：%s0, res);
    free(res);
    res = kdk_system_get_version(1);
    printf("系统详细版本：%s0, res);
    free(res);
    res = kdk_system_get_kernelVersion();
    printf("内核版本：%s0, res);
    free(res);
    res = kdk_system_get_serialNumber();
    printf("序列号：%s0, res);
    free(res);
    int p;
    int d;
    int act = kdk_system_get_activationStatus(&p,&d);
    printf("--------------0);
    printf("激活状态码：%d0,act);
    printf("激活状态：%s0, act == 1 ? "已激活" : act == 0 ? "未激活" : "已过期");

    res = kdk_system_get_eUser();
    printf("当前用户：%s0, res);
    // free(res);

    res = kdk_system_get_eUser_login_time();
    printf("登录时间：%s0, res);

    res = kdk_system_get_projectName();
    printf("项目编号名：%s0, res);
    free(res);
    int zyj = kdk_system_is_zyj();
    printf("专用机：%s0, zyj == 0 ? "非专用机":"专用机");

    res = kdk_system_get_hostVirtType();
    printf("虚拟机类型：%s0, res);
    free(res);

    res = kdk_system_get_hostCloudPlatform();
    printf("云平台类型：%s0, res);
    free(res);

    version_t test = kdk_system_get_version_detaile( );
    printf("test.os_version = %s0,test.os_version);
    printf("test.update_version = %s0,test.update_version);

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

    char *ver = kdk_system_get_systemCategory();
    printf("系统硬件版本类别 = %s0, ver);
    free(ver);

    // ver = kdk_system_get_cloudPlatformType();
    // printf("云平台类型 = %s0, ver);
    // free(ver);

    char **ud_time = kdk_system_get_startup_time();
    count = 0;
    while (ud_time[count])
    {
        printf("开机时间 = %s0, ud_time[count]);
        count++;
    }
    kdk_resolving_freeall(ud_time);

    ud_time = kdk_system_get_shutdown_time();
    count = 0;
    while (ud_time[count])
    {
        printf("关机时间 = %s0, ud_time[count]);
        count++;
    }
    kdk_resolving_freeall(ud_time);

    res = kdk_get_host_vendor();
    printf("整机制造商 = %s0, res);
    free(res);

    res = kdk_get_host_product();
    printf("整机型号 = %s0, res);
    free(res);

    res = kdk_get_host_serial();
    printf("整机序列号 = %s0, res);
    free(res);

    res = kdk_system_get_buildTime();
    printf("构建时间：%s0, res);
    free(res);

    res = kdk_system_get_hostName();
    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("slot path : %s0, tmp->slot_path);
        printf("class name :%s0, tmp->class_name);
        printf("product name :%s0, tmp->product_name);
        printf("rev :%02x0, tmp->rev);
        printf("subsystem name :%s0, tmp->ss_name);
        printf("driver user :%s0, tmp->driver_use);
        printf("modules :");
        for(int i = 0; i < tmp->module_count; i++)
        {
            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;
}
heads up bestie: in the example the free(res) right after the kdk_system_get_eUser() call is commented out — // free(res); — so it's literally sitting there in the source like that. copy it exactly, iykyk 🙈
