KDK_BOARD_GET_SERIAL(3)

✨ KDK_BOARD_GET_SERIAL ✨

okay bestie, welcome to the KDK_BOARD_GET_SERIAL(3) page from the Library Functions Manual — yes it's a manual page, yes it's section 3, yes we're gonna read it together and you're gonna understand it, periodt. 💖

🌸 NAME 🌸

kdk_board_get_serial — 获取主板序列号

(that's "get the mainboard serial number" for my monolingual girlies 🫶)

---

🎀 SYNOPSIS 🎀

#include <libkyboard.h>

extern const char* kdk_board_get_serial();

and listen — when you link this thing you gotta link with -lkyhw. no cap, the linker will simply not know her otherwise. 💅

---

🦋 Detailed Description 🦋

so the whole ~main character purpose~ of this interface is literally just: obtain the mainboard serial number. that's the function. that's the vibe. she gets the serial. slay. ✨

---

💜 RETURN VALUE 💜

• On success: it hands you back the mainboard serial number, and the type is char*. 👑
• > ⚠️ the returned string needs to be released by free — like, you gotta clean up after yourself bestie, it's not gonna free itself, and not doing it is giving memory leak energy 💀
• On error: it returns NULL. so always vibe check your pointer before you use it fr fr.

🍓 EXAMPLES 🍓

here's a whole lil program showing the girlies in action together:

#include "stdio.h"
#include "libkyboard.h"

int main()
{

    char *name = kdk_board_get_name();
    char *vendor = kdk_board_get_vendor();
    char *date = kdk_board_get_date();
    char *serial = kdk_board_get_serial();
    printf("name : %s", name);
    printf("vendor : %s", vendor);
    printf("date : %s", date);
    printf("serial : %s", serial);
    free(name);
    free(vendor);
    free(date);
    free(serial);
    return 0;
}

see how she frees all four of them at the end? that's the responsible queen behavior we stan. 🌈

🧚 CONFORMING TO 🧚

these functions are as per the withdrawn POSIX.1e draft specification — yes, withdrawn, she's a legacy icon, we respect her history. 💅

and heads up: the following functions are Linux extensions:

• kdk_board_get_vendor()
• kdk_board_get_date()
• kdk_board_get_name()
• kdk_board_free()

so don't go expecting those ones to be all portable and POSIX-y, iykyk. 🙈
