[SOLVED] Unable to read data by QDataStream

[karankumar1609]

Hello All,

I am currently trying to read data from socket, but it is something new to me that i want to read a structure from socket.
I have the following structure with implemented overloaded <<, and >> operator

typedef struct hShakeAckPkt
{
    unsigned short Id;              // 0XFEFE
    unsigned short BlockSize;       // 45
    long Reserved1[2];               // fill with 0
    unsigned short FeedType;        // fill with 0
    unsigned short Reserved2[3];    // fill with 0
    unsigned short Major;           // 1
    unsigned short Minor;           // 4
    unsigned char ProgramId[21];    // "CTCL" rest with '\0'
 
}hShakeAckPkt;
 
QDataStream & operator << (QDataStream &out, const hShakeAckPkt &hand_shake_pkt);
QDataStream & operator >> (QDataStream &in, hShakeAckPkt &hand_shake_pkt);

typedef struct hShakeAckPkt
{
    unsigned short Id;              // 0XFEFE
    unsigned short BlockSize;       // 45
    long Reserved1[2];               // fill with 0
    unsigned short FeedType;        // fill with 0
    unsigned short Reserved2[3];    // fill with 0
    unsigned short Major;           // 1
    unsigned short Minor;           // 4
    unsigned char ProgramId[21];    // "CTCL" rest with '\0'

}hShakeAckPkt;

QDataStream & operator << (QDataStream &out, const hShakeAckPkt &hand_shake_pkt);
QDataStream & operator >> (QDataStream &in, hShakeAckPkt &hand_shake_pkt);

for reading from datastream i have implemented the above operator as :

QDataStream &operator <<(QDataStream &out, const hShakeAckPkt &hand_shake_pkt)
{
    out << hand_shake_pkt.Id;
    out << hand_shake_pkt.BlockSize;
    out.writeRawData(reinterpret_cast<const char*>(hand_shake_pkt.Reserved1), 2);
    out << hand_shake_pkt.FeedType;
    out.writeRawData(reinterpret_cast<const char*>(hand_shake_pkt.Reserved2), 3);
    out << hand_shake_pkt.Major;
    out << hand_shake_pkt.Minor;
    out.writeRawData(reinterpret_cast<const char*>(hand_shake_pkt.ProgramId), 21);
 
    return out;
}
 
QDataStream &operator >>(QDataStream &in, hShakeAckPkt &hand_shake_pkt)
{
    in >> hand_shake_pkt.Id;
    in >> hand_shake_pkt.BlockSize;
    in.readRawData(reinterpret_cast<char*>(hand_shake_pkt.Reserved1), 2);
    in >> hand_shake_pkt.FeedType;
    in.readRawData(reinterpret_cast<char*>(hand_shake_pkt.Reserved2), 3);
    in >> hand_shake_pkt.Major;
    in >> hand_shake_pkt.Minor;
    in.readRawData(reinterpret_cast<char*>(hand_shake_pkt.ProgramId), 21);
 
    return in;
}

QDataStream &operator <<(QDataStream &out, const hShakeAckPkt &hand_shake_pkt)
{
    out << hand_shake_pkt.Id;
    out << hand_shake_pkt.BlockSize;
    out.writeRawData(reinterpret_cast<const char*>(hand_shake_pkt.Reserved1), 2);
    out << hand_shake_pkt.FeedType;
    out.writeRawData(reinterpret_cast<const char*>(hand_shake_pkt.Reserved2), 3);
    out << hand_shake_pkt.Major;
    out << hand_shake_pkt.Minor;
    out.writeRawData(reinterpret_cast<const char*>(hand_shake_pkt.ProgramId), 21);

    return out;
}

QDataStream &operator >>(QDataStream &in, hShakeAckPkt &hand_shake_pkt)
{
    in >> hand_shake_pkt.Id;
    in >> hand_shake_pkt.BlockSize;
    in.readRawData(reinterpret_cast<char*>(hand_shake_pkt.Reserved1), 2);
    in >> hand_shake_pkt.FeedType;
    in.readRawData(reinterpret_cast<char*>(hand_shake_pkt.Reserved2), 3);
    in >> hand_shake_pkt.Major;
    in >> hand_shake_pkt.Minor;
    in.readRawData(reinterpret_cast<char*>(hand_shake_pkt.ProgramId), 21);

    return in;
}

The problem is when i read the data it is not the original one.
And what is the procedure to read array??

Anyone have idea about that?
