如何通过pthread发送套接字id？

#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <pthread.h>
#include <sys/socket.h>
#include <netinet/in.h>

void* threadFunc(void* arg) {
    int sockfd = *(int*)arg;
    // 在这里可以使用sockfd进行网络通信操作
    // 例如发送和接收数据
    printf("Thread: Sending data using socket %d\n", sockfd);
    // ...
    return NULL;
}

int main() {
    int sockfd;
    struct sockaddr_in serverAddr;

    // 创建套接字
    sockfd = socket(AF_INET, SOCK_STREAM, 0);
    if (sockfd < 0) {
        perror("Failed to create socket");
        exit(EXIT_FAILURE);
    }

    // 绑定套接字到特定的IP地址和端口号
    serverAddr.sin_family = AF_INET;
    serverAddr.sin_port = htons(12345);
    serverAddr.sin_addr.s_addr = INADDR_ANY;
    if (bind(sockfd, (struct sockaddr*)&serverAddr, sizeof(serverAddr)) < 0) {
        perror("Failed to bind socket");
        exit(EXIT_FAILURE);
    }

    // 创建新的线程，并将套接字id作为参数传递给线程
    pthread_t thread;
    if (pthread_create(&thread, NULL, threadFunc, &sockfd) != 0) {
        perror("Failed to create thread");
        exit(EXIT_FAILURE);
    }

    // 等待新创建的线程执行完毕
    if (pthread_join(thread, NULL) != 0) {
        perror("Failed to join thread");
        exit(EXIT_FAILURE);
    }

    // 关闭套接字并释放资源
    close(sockfd);

    return 0;
}
