KDK_GET_PROCESS_MEM_USAGE_PERCENT(3)

💖 KDK_GET_PROCESS_MEM_USAGE_PERCENT(3) 💖

okay bestie, welcome to the Library Functions Manual page for kdk_get_process_mem_usage_percent — yes the whole name is a mouthful, we're saying it with our chest 💅

---

✨ NAME ✨

kdk_get_process_mem_usage_percent — 获取某一进程的内存占用率 (that's "get the memory usage percent of a process", for my monolingual girlies 🫶)

---

🌸 SYNOPSIS 🌸

#include <libkyprocess.h>

extern float kdk_get_process_mem_usage_percent(int proc_num);

Link with -lkyrtinfo.

---

🦋 Detailed Description 🦋

The main function of this interface is to obtain the memory usage of the specified process. That's it, that's the whole job, and it does it flawlessly ✨

The argument proc_num is the PID of the process. Like, the actual process ID number, not a name, not a vibe, a number. iykyk.

---

🎀 RETURN VALUE 🎀

• On success, it returns the memory usage of the process, of type float. slay 💅
• On error, it returns 0.00 — so if you get a flat zero, that's the code being like "idk her" 😭

---

🌈 EXAMPLES 🌈

Here's the whole friend-group of calls hanging out together, no cap:

#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;
}

⚠️ bestie, notice all those free(...) calls and the kdk_proc_freeall(...) cleanups? Those are the mandatory goodbye hugs. Don't ghost your allocations, it's not the vibe 🙈
