KDK_GET_PROCESS_CPU_TIME(3)

KDK_GET_PROCESS_CPU_TIME 💅

okay bestie, so this one lives in the Library Functions Manual section of the Linux Programmer's Manual — it's kdk_get_process_cpu_time(3), and yes she's that girl 🎀

---

✨ NAME ✨

kdk_get_process_cpu_time — 获取某一进程的cpu时间 🌸

(translation for my monolingual girlies: it grabs the CPU time of a process, no cap)

---

🦋 SYNOPSIS 🦋

#include <libkyprocess.h>

extern char* kdk_get_process_cpu_time(int proc_num);

Link with -lkyrtinfo.

---

💖 Detailed Description 💖

so the whole main character job of this interface is, like, getting the CPU time of the process you point at. that's it. that's the vibe. ✨

The argument proc_num is the PID of the process. literally just hand her the PID and she'll do the rest 🫶

---

👑 RETURN VALUE 👑

On success, returns the CPU time of the process of type char*, such as "58秒" — iconic format, we love to see it 💅

The returned string needs to be released by free — bestie. please. free it. don't leave her hanging, that's a memory leak and leaks are NOT cute 😭

On error, return NULL. 💀

🌈 EXAMPLES 🌈

here's the whole group chat, everybody showing up at once:

#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;
}

(and yes, that's the code exactly as it is — not me being sloppy, I promise, I don't edit the source, that's the rule 🧚)
