獲取本機子網掩碼、廣播地址

//在上個函式的環境下
QList<QNetworkAddressEntry> entryList =interface.addressEntries();
//獲取IP地址條目列表，每個條目中包含一個IP地址，一個子網掩碼和一個廣播地址

    //遍歷每一個IP地址條目
qDebug()<<”IP Address:
            “<<entry.ip().toString();
    //IP地址
qDebug()<<”Netmask:
            “<<entry.netmask().toString();
    //子網掩碼
qDebug()<<”Broadcast:
            “<<entry.broadcast().toString();
    //廣播地址
