KDK_BLUETOOTH_GET_BUS(3)

💖 KDK_BLUETOOTH_GET_BUS(3) 💖

okay bestie, welcome to the Library Functions Manual section of the kdk universe — today's main character is kdk_bluetooth_get_bus, and she is, and I say this with my whole chest, the girl who tells you which bus your bluetooth is riding 🚌✨

---

✨ NAME ✨

kdk_bluetooth_get_bus — 获取蓝牙的总线 (that's "get the bus of Bluetooth", and yes she's bilingual, we love a polyglot queen 👑)

---

🎀 SYNOPSIS 🎀

#include <libkybluetooth.h>

extern char* kdk_bluetooth_get_bus(int id);

and listen, you gotta link it, no cap:

Link with -lkybluetooth.

---

🦋 Detailed Description 🦋

So the whole ~point~ of this function, its entire vibe, its main character moment, is: obtain the bus of Bluetooth. That's it. That's the function.

And the argument, id? That's the device ID of Bluetooth. Just the ID. You hand her the ID, she hands you the bus. Transactional. Iconic. 💅

---

🌸 RETURN VALUE 🌸

• On success, you get back the Bluetooth bus, type char* — and bestie, pay attention: the returned string needs to be released by free. She gives you the goods, but you're the one who has to clean up after. Free your strings. Be a responsible legend. 🫶
• On error, you get NULL. Nothing. Nada. A little "no thoughts, head empty" moment. 😭

💀 EXAMPLES 💀

here's the whole demo, verbatim, no edits, she's perfect the way she is:

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

int main()
{
    int i = 0;
    char *manufacturer = " ";
    char *version = " ";
    char *name = " ";
    char *address = " ";
    char *link_mode  =" ";
    char *link_policy =" ";
    char *scomtu = " ";
    char *alcmtu = " ";
    char *packettype = " ";
    char *features = " ";
    char *bus = " ";
    int **id = kdk_bluetooth_get_device_id();
    do
    {
        printf("id = %d0,id[i]);
        manufacturer = kdk_bluetooth_get_manufacturer(i);
        printf("manufacturer: %s0, manufacturer);
        free(manufacturer);
        version = kdk_bluetooth_get_dev_version(i);
        printf("version: %s0, version);
        free(version);
        name = kdk_bluetooth_get_name(id[i]);
        printf("name: %s0, name);
        address = kdk_bluetooth_get_address(id[i]);
        printf("address: %s0, address);
        link_mode = kdk_bluetooth_get_link_mode(id[i]);
        printf("link_mode: %s0, link_mode);
        link_policy = kdk_bluetooth_get_link_policy(id[i]);
        printf("link_policy: %s0, link_policy);
        scomtu = kdk_bluetooth_get_scomtu(id[i]);
        printf("scomtu: %s0, scomtu);
        alcmtu = kdk_bluetooth_get_alcmtu(id[i]);
        printf("alcmtu: %s0, alcmtu);
        packettype = kdk_bluetooth_get_packettype(id[i]);
        printf("packettype: %s0, packettype);
        features = kdk_bluetooth_get_features(id[i]);
        printf("features: %s0, features);
        bus = kdk_bluetooth_get_bus(id[i]);
        printf("bus: %s0, bus);
        i++;
    }while(id[i]);
    return 0;
}

notice how she calls free on manufacturer and version and not on the rest? yeah. that's the example. that's what it does. don't @ me, I'm just the messenger 🧚
