VxWorks实现网络通信的示例代码与解析

这示例展示了如何使用VxWorks操作系统实现基本的网络通信功能。代码中演示了建立套接字、发送和接收数据的过程，展现了VxWorks的网络模块的基本用法。

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

void main()
{
    int serverSocket, clientSocket;
    struct sockaddr_in serverAddr, clientAddr;
    int addrLen = sizeof(struct sockaddr_in);

    // 创建套接字
    serverSocket = socket(AF_INET, SOCK_STREAM, 0);

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

    // 绑定套接字
    bind(serverSocket, (struct sockaddr *)&serverAddr, sizeof(serverAddr));

    // 监听
    listen(serverSocket, 5);

    // 接受连接
    clientSocket = accept(serverSocket, (struct sockaddr *)&clientAddr, &addrLen);

    // 发送数据
    send(clientSocket, "Hello from server", 18, 0);

    // 接收数据
    char buffer[100];
    recv(clientSocket, buffer, sizeof(buffer), 0);
    printf("Received message: %s\n", buffer);

    // 关闭套接字
    close(clientSocket);
    close(serverSocket);
}
