如何使用libnl将我的设备连接到wifi？

sudo apt-get install libnl-3-dev libnl-genl-3-dev

#include <netlink/netlink.h>
#include <netlink/genl/genl.h>
#include <netlink/genl/ctrl.h>
#include <linux/nl80211.h>

struct nl_sock *sock;
int driver_id;

// 初始化 netlink socket
sock = nl_socket_alloc();
if (!sock) {
    fprintf(stderr, "Failed to allocate netlink socket.\n");
    return -1;
}

// 绑定和连接 socket
if (genl_connect(sock)) {
    fprintf(stderr, "Failed to connect to generic netlink.\n");
    nl_socket_free(sock);
    return -1;
}

// 解析 nl80211 driver ID
driver_id = genl_ctrl_resolve(sock, "nl80211");
if (driver_id < 0) {
    fprintf(stderr, "nl80211 not found.\n");
    nl_socket_free(sock);
    return -1;
}

struct nl_msg *msg;
int ret;

msg = nlmsg_alloc();
if (!msg) {
    fprintf(stderr, "Failed to allocate netlink message.\n");
    nl_socket_free(sock);
    return -1;
}

genlmsg_put(msg, 0, 0, driver_id, 0, 0, NL80211_CMD_CONNECT, 0);

// 添加 SSID
nla_put(msg, NL80211_ATTR_SSID, ssid_len, ssid);

// 设置接口索引
nla_put_u32(msg, NL80211_ATTR_IFINDEX, if_index);

// 发送消息
ret = nl_send_auto(sock, msg);
nlmsg_free(msg);
if (ret < 0) {
    fprintf(stderr, "Failed to send connect command.\n");
    nl_socket_free(sock);
    return -1;
}

// 接收内核的响应
nl_recvmsgs_default(sock);

nl_socket_free(sock);
