VxWorks中实现UDP通信的示例代码

该示例代码演示了如何在VxWorks操作系统中通过UDP协议进行通信，包括创建socket、绑定地址、发送和接收数据等操作。

/* 创建socket */
int socketFd = socket(AF_INET, SOCK_DGRAM, 0);
if (socketFd == ERROR) {
    printf("Failed to create socket.\n");
    return ERROR;
}

/* 绑定地址 */
sockaddr_in localAddr;
bzero((char *) &localAddr, sizeof(localAddr));
localAddr.sin_family = AF_INET;
localAddr.sin_port = htons(PORT);
localAddr.sin_addr.s_addr = inet_addr(LOCAL_IP);
if (bind(socketFd, (struct sockaddr *)&localAddr, sizeof(localAddr)) == ERROR) {
    printf("Failed to bind socket.\n");
    return ERROR;
}

/* 发送数据 */
sockaddr_in sendAddr;
bzero((char *) &sendAddr, sizeof(sendAddr));
sendAddr.sin_family = AF_INET;
sendAddr.sin_port = htons(DEST_PORT);
sendAddr.sin_addr.s_addr = inet_addr(DEST_IP);
if (sendto(socketFd, sendData, SEND_DATA_LEN, 0,
    (struct sockaddr *)&sendAddr, sizeof(sendAddr)) == ERROR) {
    printf("Failed to send data.\n");
    return ERROR;
}

/* 接收数据 */
sockaddr_in recvAddr;
bzero((char *) &recvAddr, sizeof(recvAddr));
int addrLen = sizeof(recvAddr);
if (recvfrom(socketFd, recvData, RECV_DATA_LEN, 0,
    (struct sockaddr *)&recvAddr, &addrLen) == ERROR) {
    printf("Failed to receive data.\n");
    return ERROR;
}

/* 关闭socket */
if (close(socketFd) == ERROR) {
    printf("Failed to close socket.\n");
    return ERROR;
}
