如何在C套接字(sys/socket.h)中获取客户端的地址和端口？

#include <stdio.h>
#include <stdlib.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <arpa/inet.h>

int main() {
    int serverSocket, clientSocket;
    struct sockaddr_in serverAddr, clientAddr;
    socklen_t addrLen = sizeof(clientAddr);

    // 创建套接字
    serverSocket = socket(AF_INET, SOCK_STREAM, 0);
    if (serverSocket < 0) {
        perror("socket creation failed");
        exit(EXIT_FAILURE);
    }

    // 绑定地址和端口
    serverAddr.sin_family = AF_INET;
    serverAddr.sin_addr.s_addr = INADDR_ANY;
    serverAddr.sin_port = htons(8080);
    if (bind(serverSocket, (struct sockaddr *)&serverAddr, sizeof(serverAddr)) < 0) {
        perror("bind failed");
        exit(EXIT_FAILURE);
    }

    // 监听连接请求
    if (listen(serverSocket, 5) < 0) {
        perror("listen failed");
        exit(EXIT_FAILURE);
    }

    // 接受客户端连接
    clientSocket = accept(serverSocket, (struct sockaddr *)&clientAddr, &addrLen);
    if (clientSocket < 0) {
        perror("accept failed");
        exit(EXIT_FAILURE);
    }

    // 获取客户端地址和端口
    char clientIP[INET_ADDRSTRLEN];
    inet_ntop(AF_INET, &(clientAddr.sin_addr), clientIP, INET_ADDRSTRLEN);
    int clientPort = ntohs(clientAddr.sin_port);

    printf("Client IP: %s\n", clientIP);
    printf("Client Port: %d\n", clientPort);

    // 关闭套接字
    close(clientSocket);
    close(serverSocket);

    return 0;
}
