KDK_CPU_GET_PROCESS(3)

✨ KDK_CPU_GET_PROCESS(3) ✨

okay bestie, gather round, because we're about to talk about a manual page from the Library Functions Manual and honestly? it's giving utilities. this is kdk_cpu_get_process and it's the little function that tells you how many CPU threads your machine is working with. no cap, she's simple, she's reliable, she's the friend who always texts back. 💅

💖 NAME 💖

kdk_cpu_get_process — 获取CPU线程数

(yes, that's the name, and yes, the description is in Chinese, we're keeping it exactly as it is, multilingual queen 🫶)

---

🌸 SYNOPSIS 🌸

#include <libkycpu.h>

extern unsigned int kdk_cpu_get_process()

and listen — you gotta link with -lkyhw or she simply will not show up. periodt.

---

🦋 Detailed Description 🦋

so like, the whole vibe of this interface? the main function of the interface is to obtain the number of CPU thread. that's it. that's the job. she counts threads. lowkey iconic behavior. 🌈

---

⭐ RETURN VALUE ⭐

• On success — returns the number of all available CPU thread of type int. slay, numbers, we love to see it ✨
• On error — return 0. not a throw, not a signal, just a humble little zero. if you see a 0, something went sideways, bestie 😭

🎀 EXAMPLES 🎀

here's the whole squad living their best life together in one little program:

#include "libkycpu.h"
#include <stdio.h>

int main()
{
    printf("架构：%s\n", kdk_cpu_get_arch());
    printf("生产厂商：%s\n", kdk_cpu_get_vendor());
    printf("CPU 型号：%s\n", kdk_cpu_get_model());
    printf("CPU 主频：%s MHz\n", kdk_cpu_get_freq_MHz());
    printf("CPU 单核核心数量：%u\n", kdk_cpu_get_corenums());
    printf("CPU 虚拟化支持：%s\n", kdk_cpu_get_virt());
    printf("CPU 线程数：%u\n", kdk_cpu_get_process());
    return 0;
}

look at her. kdk_cpu_get_process() right there at the bottom, printing 线程数 like the main character she is. 👑

💜 CONFORMING TO 💜

These functions are as per the withdrawn POSIX.1e draft specification.

and then, the plot twist: The following functions are Linux extensions: kdk_cpu_get_vendor(), kdk_cpu_get_model(), kdk_cpu_get_freq_MHz(), kdk_cpu_get_arch(), kdk_cpu_get_virt() and kdk_cpu_get_corenums().

so if you were hoping this was portable across every Unix ever... it's not, bestie. those listed ones are Linux-only extensions, iykyk. 🐧

and that's the whole page, fr fr. this came to you from the Linux Programmer's Manual, dated Thu Aug 24 2023, filed under KDK_CPU_GET_PROCESS(3) — stay hydrated, count your threads, and go touch some printfs. bye bestie 💖🧚💅
