如何在c/c++套接字编程中绑定地址？

#include <iostream>
#include <cstring>
#include <arpa/inet.h>

int main() {
    // 创建套接字
    int sockfd = socket(AF_INET, SOCK_STREAM, 0);
    if (sockfd == -1) {
        std::cerr << "Failed to create socket." << std::endl;
        return -1;
    }

    // 定义并初始化地址结构
    sockaddr_in addr;
    std::memset(&addr, 0, sizeof(addr));
    addr.sin_family = AF_INET;
    addr.sin_addr.s_addr = htonl(INADDR_ANY);  // INADDR_ANY表示任意地址
    addr.sin_port = htons(8080);  // 绑定的端口号

    // 绑定地址
    if (bind(sockfd, (struct sockaddr*)&addr, sizeof(addr)) == -1) {
        std::cerr << "Failed to bind address." << std::endl;
        close(sockfd);
        return -1;
    }

    std::cout << "Address binding successful." << std::endl;

    // 其他操作...

    close(sockfd);

    return 0;
}
