{ TcpHeartbeat=200, TcpExeCmd }; // 定义结构体 struct DataPacket { int clientSockfd; enum Choose choose; char *cmdBuf; char *returnValue; }; struct DataPacket datapacket; struct DataPacket ReceivePackets; 在c语言tcp socket通信中，datapacket结构体为write通信发送的包，ReceivePackets结构体为read发送的包，帮我写出通信部分，连接部分不用写

下面是一个简单的C语言TCP Socket通信的示例代码，其中包括了发送和接收数据的部分。请注意，这只是一个基本的示例，实际应用中可能需要根据具体需求进行修改和扩展。

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

// 定义结构体
enum Choose {
    TcpHeartbeat = 200,
    TcpExeCmd
};

struct DataPacket {
    int clientSockfd;
    enum Choose choose;
    char *cmdBuf; 
    char *returnValue;
};

int main() {
    int clientSocket;
    struct sockaddr_in serverAddress;
    struct DataPacket datapacket, ReceivePackets;

    // 创建套接字
    clientSocket = socket(AF_INET, SOCK_STREAM, 0);
    if (clientSocket == -1) {
        perror("Failed to create socket");
        exit(EXIT_FAILURE);
    }

    // 设置服务器地址
    serverAddress.sin_family = AF_INET;
    serverAddress.sin_port = htons(8080); // 服务器端口号
    serverAddress.sin_addr.s_addr = inet_addr("127.0.0.1"); // 服务器IP地址

    // 连接服务器
    if (connect(clientSocket, (struct sockaddr*)&serverAddress, sizeof(serverAddress)) < 0) {
        perror("Failed to connect to server");
        exit(EXIT_FAILURE);
    }

    // 发送数据包
    datapacket.clientSockfd = clientSocket;
    datapacket.choose = TcpExeCmd;
    datapacket.cmdBuf = "Command";
    datapacket.returnValue = "";

    if (send(clientSocket, &datapacket, sizeof(datapacket), 0) == -1) {
        perror("Failed to send data");
        exit(EXIT_FAILURE);
    }

    // 接收数据包
    if (recv(clientSocket, &ReceivePackets, sizeof(ReceivePackets), 0) == -1) {
        perror("Failed to receive data");
        exit(EXIT_FAILURE);
    }

    // 处理接收到的数据包
    printf("Received data:\n");
    printf("clientSockfd: %d\n", ReceivePackets.clientSockfd);
    printf("choose: %d\n", ReceivePackets.choose);
    printf("cmdBuf: %s\n", ReceivePackets.cmdBuf);
    printf("returnValue: %s\n", ReceivePackets.returnValue);

    // 关闭套接字
    close(clientSocket);

    return 0;
}

请根据实际情况修改服务器地址、端口号和数据包内容。这段代码发送了一个`datapacket`结构体，然后接收并处理了一个`ReceivePackets`结构体。你可以根据自己的需求进行进一步的处理和扩展。
