VxWorks网络编程实例：TCP套接字通信与数据传输

本示例演示在VxWorks实时操作系统中使用TCP套接字进行网络通信，并展示数据的传输过程。通过简单的服务器和客户端代码，了解VxWorks网络编程的基本原理和操作。

#include <vxWorks.h>
#include <sockLib.h>
#include <inetLib.h>

void tcpServer() {
    int listenSock, acceptSock;
    struct sockaddr_in serverAddr, clientAddr;
    int clientAddrLen = sizeof(clientAddr);
    char buffer[256];

    listenSock = socket(AF_INET, SOCK_STREAM, 0);

    bzero((char *)&serverAddr, sizeof(serverAddr));
    serverAddr.sin_family = AF_INET;
    serverAddr.sin_addr.s_addr = htonl(INADDR_ANY);
    serverAddr.sin_port = htons(12345);

    bind(listenSock, (struct sockaddr *)&serverAddr, sizeof(serverAddr));
    listen(listenSock, 5);

    acceptSock = accept(listenSock, (struct sockaddr *)&clientAddr, &clientAddrLen);

    while (1) {
        bzero(buffer, sizeof(buffer));
        recv(acceptSock, buffer, sizeof(buffer), 0);
        printf("接收到客户端消息：%s\n", buffer);

        // 在这里进行数据处理或其他业务逻辑

        send(acceptSock, "服务器已收到消息", 18, 0);
    }
}

void tcpClient() {
    int clientSock;
    struct sockaddr_in serverAddr;
    char message[] = "Hello, VxWorks!";

    clientSock = socket(AF_INET, SOCK_STREAM, 0);

    bzero((char *)&serverAddr, sizeof(serverAddr));
    serverAddr.sin_family = AF_INET;
    serverAddr.sin_addr.s_addr = inet_addr("192.168.1.100"); // 服务器的IP地址
    serverAddr.sin_port = htons(12345);

    connect(clientSock, (struct sockaddr *)&serverAddr, sizeof(serverAddr));

    send(clientSock, message, sizeof(message), 0);

    // 在这里处理服务器响应或进行其他业务逻辑
}

// 在启动任务或其他适当位置调用 tcpServer() 和 tcpClient() 函数
