💖 KDK_GET_PROCESS_USER(3) 💖

okay bestie, welcome to the Library Functions Manual section, we're talking about kdk_get_process_user today and honestly? she's iconic. 🌸


✨ NAME ✨

kdk_get_process_user — 获取某一进程的属主 (aka: find out which user owns a process, slay)


🦋 SYNOPSIS 🦋

#include <libkyprocess.h>

extern char* kdk_get_process_user(int proc_num);

Link with -lkyrtinfo.


💅 Detailed Description 💅

so the main character job of this interface? it gets you the name of the user account that started the specified process. that's it. that's the whole vibe. 🎀

the argument proc_num is the PID of the process. yes, the actual process ID. no cap.


👑 RETURN VALUE 👑

  • on success — you get back the name of the user account that started the process, as a char*, like "root" for example. and listen: the returned string needs to be released by free. don't forget. i'm begging you. 😭
  • on error — it returns NULL.

🌈 EXAMPLES 🌈

here's the whole thing in action, look at her go:

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

int main()
{
    char *run_time = kdk_get_process_running_time(841);
    char *cpu_time = kdk_get_process_cpu_time(841);
    char *cmd = kdk_get_process_command(841);
    char *start_time = kdk_get_process_start_time(841);
    printf("获取某一进程的CPU利用率:%0.1f0, kdk_get_process_cpu_usage_percent(841));
    printf("获取某一进程的内存占用率:%0.1f0, kdk_get_process_mem_usage_percent(841));
    printf("获取某一进程的进程状态:%s0, kdk_get_process_status(841));
    printf("获取某一进程的进程端口号:%d0, kdk_get_process_port(841));
    printf("获取某一进程的启动时间:%s0, start_time);
    printf("获取某一进程的运行时间:%s0, run_time);
    printf("获取某一进程的CPU时间:%s0, cpu_time);
    printf("获取某一进程的Command:%s0, cmd);
    printf("获取某一进程的属主:%s0, kdk_get_process_user(841));
    free(run_time);
    free(cpu_time);
    free(cmd);
    free(start_time);
    char** pid =  kdk_procname_get_process_infomation("systemd");
    size_t index = 0;
    while (pid[index])
    {
        printf("pid %s0, pid[index]);
        index ++;
    }
    kdk_proc_freeall(pid);

    char** info = kdk_get_process_all_information();
    size_t count = 0;
    while (info[count])
    {
        printf("No. %d %s0, count + 1, info[count]);
        count ++;
    }
    kdk_proc_freeall(info);

    char *name = kdk_get_process_name(1151571);
    printf("name = %s0, name);
    free(name);

    int id =  kdk_get_process_id("systemd");
    printf("pid %d0, id);

    return 0;
}

periodt. copy it, run it, live your truth. 💜
