VxWorks实现网络通信示例与技术解答

本示例展示了如何使用VxWorks实现基本的网络通信功能，包括建立连接、发送和接收数据。通过使用VxWorks提供的网络库函数，可以轻松地创建一个简单的TCP/IP通信应用程序。

#include <stdio.h>
#include <string.h>
#include <netinet/in.h>
#include <arpa/inet.h>
#include <sockLib.h>

void networkCommunication() {
    int serverSock, clientSock;
    struct sockaddr_in serverAddr, clientAddr;
    char buffer[1024];

    // 创建服务器套接字
    serverSock = socket(AF_INET, SOCK_STREAM, 0);
    if (serverSock == ERROR) {
        perror("Socket creation failed");
        return;
    }

    bzero((char *)&serverAddr, sizeof(serverAddr));
    serverAddr.sin_family = AF_INET;
    serverAddr.sin_addr.s_addr = htonl(INADDR_ANY);
    serverAddr.sin_port = htons(8080);

    // 绑定套接字
    if (bind(serverSock, (struct sockaddr *)&serverAddr, sizeof(serverAddr)) == ERROR) {
        perror("Binding failed");
        close(serverSock);
        return;
    }

    // 监听连接
    if (listen(serverSock, 5) == ERROR) {
        perror("Listening failed");
        close(serverSock);
        return;
    }

    // 接受客户端连接
    int clientAddrLen = sizeof(clientAddr);
    clientSock = accept(serverSock, (struct sockaddr *)&clientAddr, &clientAddrLen);
    if (clientSock == ERROR) {
        perror("Accepting connection failed");
        close(serverSock);
        return;
    }

    // 接收数据
    recv(clientSock, buffer, sizeof(buffer), 0);
    printf("Received message: %s\n", buffer);

    // 发送数据
    strcpy(buffer, "Message received!");
    send(clientSock, buffer, strlen(buffer), 0);

    close(clientSock);
    close(serverSock);
}
