智能家居系统服务器模块用c语言编写的代码

以下是一个简单的智能家居系统服务器模块的C语言代码示例：

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <sys/socket.h>
#include <arpa/inet.h>
#include <unistd.h>

#define MAX_CLIENTS 10
#define BUFFER_SIZE 1024

int main(int argc, char *argv[]) {
    int server_socket, client_sockets[MAX_CLIENTS];
    struct sockaddr_in server_addr, client_addr;
    char buffer[BUFFER_SIZE];

    // 创建服务器套接字
    server_socket = socket(AF_INET, SOCK_STREAM, 0);
    if (server_socket == -1) {
        perror("Failed to create socket");
        exit(EXIT_FAILURE);
    }

    // 设置服务器地址
    server_addr.sin_family = AF_INET;
    server_addr.sin_addr.s_addr = INADDR_ANY;
    server_addr.sin_port = htons(8080);

    // 绑定服务器套接字到指定地址和端口
    if (bind(server_socket, (struct sockaddr *)&server_addr, sizeof(server_addr)) < 0) {
        perror("Failed to bind socket");
        exit(EXIT_FAILURE);
    }

    // 监听客户端连接请求
    if (listen(server_socket, MAX_CLIENTS) < 0) {
        perror("Failed to listen for connections");
        exit(EXIT_FAILURE);
    }

    printf("Server started. Waiting for connections...\n");

    while (1) {
        socklen_t client_len = sizeof(client_addr);

        // 接受客户端连接请求
        int client_socket = accept(server_socket, (struct sockaddr *)&client_addr, &client_len);
        if (client_socket < 0) {
            perror("Failed to accept client connection");
            exit(EXIT_FAILURE);
        }

        printf("Client connected: %s:%d\n", inet_ntoa(client_addr.sin_addr), ntohs(client_addr.sin_port));

        // 将客户端套接字加入到客户端套接字列表
        int i;
        for (i = 0; i < MAX_CLIENTS; i++) {
            if (client_sockets[i] == 0) {
                client_sockets[i] = client_socket;
                break;
            }
        }

        // 读取客户端发送的数据
        memset(buffer, 0, sizeof(buffer));
        int bytes_read = read(client_socket, buffer, sizeof(buffer));
        if (bytes_read < 0) {
            perror("Failed to read data from client");
            exit(EXIT_FAILURE);
        }

        printf("Received data from client: %s\n", buffer);

        // 向客户端发送响应数据
        char response[] = "Hello from server!";
        if (write(client_socket, response, strlen(response)) < 0) {
            perror("Failed to send response to client");
            exit(EXIT_FAILURE);
        }

        // 关闭客户端套接字
        close(client_socket);
    }

    // 关闭服务器套接字
    close(server_socket);

    return 0;
}

这段代码创建了一个基本的服务器，使用TCP协议监听8080端口。它可以接受多个客户端的连接请求，并读取客户端发送的数据，然后向客户端发送响应数据。请注意，这只是一个简单的示例，实际的智能家居系统服务器可能需要更复杂的逻辑和功能
