KDK_BLUETO...T_FEATURES(3)

💖 KDK_BLUETO...T_FEATURES(3) — Library Functions Manual 💖

okay bestie, welcome to the kdk_bluetooth_get_features page, straight out of the Library Functions Manual. this one's a lil function that tells you what your Bluetooth device can actually do. let's get into it 🦋

---

✨ NAME ✨

kdk_bluetooth_get_features — 获取蓝牙的功能 (aka: go get the features of the Bluetooth, bb 💅)

---

✨ SYNOPSIS ✨

#include <libkybluetooth.h>

extern char* kdk_bluetooth_get_features(int id);

Link with -lkybluetooth.

---

✨ Detailed Description ✨

so like, the main character of this whole interface? it's getting the features of Bluetooth. that's the job. that's the assignment. 👑

and the argument, id, is the device ID of Bluetooth. that's the lil ticket you hand over so it knows which Bluetooth you're asking about.

---

✨ RETURN VALUE ✨

• On success — you get back the Bluetooth features, type char*. and listen, bestie, that returned string is yours to free. it needs to be released by free. don't leave it hanging, that's rude. 🙈
• On error — return NULL. that's it. that's the whole vibe. 💀

✨ EXAMPLES ✨

here's the full demo, copied exactly, no notes, just vibes:

#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;
}
