Fastest way to read structure from QTcpSocket

[karankumar1609]

Hello All,

I have got one problem which is resolved in http://www.qtcentre.org/threads/57634-SOLVED-Unable-to-read-data-by-QDataStream .
But i want to know that, is there any other fastest way to read all the data from socket in a structure.

My current structure is

typedef struct hShakeAckPkt
    {
    unsigned short Id; // 0XFEFE
    unsigned short BlockSize; // 45
    int 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
    int 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);

To copy to clipboard, switch view to plain text mode 

And the code for reading the data from the socket is

QDataStream &operator <<(QDataStream &out, const hShakeAckPkt &hand_shake_pkt)
    {
    out << hand_shake_pkt.Id;
    out << hand_shake_pkt.BlockSize;
 
    for(int i = 0; i < 2; ++i)
    out << hand_shake_pkt.Reserved1[i];
 
    out << hand_shake_pkt.FeedType;
 
    for(int i = 0; i < 3; ++i)
    out << hand_shake_pkt.Reserved2[i];
 
    out << hand_shake_pkt.Major;
    out << hand_shake_pkt.Minor;
 
    for(int i = 0; i < 21; ++i)
    out << hand_shake_pkt.ProgramId[i];
 
    return out;
    }
 
    QDataStream &operator >>(QDataStream &in, hShakeAckPkt &hand_shake_pkt)
    {
    in >> hand_shake_pkt.Id;
    in >> hand_shake_pkt.BlockSize;
 
    for(int i = 0; i < 2; ++i)
    in >> hand_shake_pkt.Reserved1[i];
 
    in >> hand_shake_pkt.FeedType;
 
    for(int i = 0; i < 3; ++i)
    in >> hand_shake_pkt.Reserved2[i];
 
    in >> hand_shake_pkt.Major;
    in >> hand_shake_pkt.Minor;
 
    for(int i = 0; i < 21; ++i)
    in >> hand_shake_pkt.ProgramId[i];
 
    return in;
    }

QDataStream &operator <<(QDataStream &out, const hShakeAckPkt &hand_shake_pkt)
    {
    out << hand_shake_pkt.Id;
    out << hand_shake_pkt.BlockSize;
     
    for(int i = 0; i < 2; ++i)
    out << hand_shake_pkt.Reserved1[i];
     
    out << hand_shake_pkt.FeedType;
     
    for(int i = 0; i < 3; ++i)
    out << hand_shake_pkt.Reserved2[i];
     
    out << hand_shake_pkt.Major;
    out << hand_shake_pkt.Minor;
     
    for(int i = 0; i < 21; ++i)
    out << hand_shake_pkt.ProgramId[i];
     
    return out;
    }
     
    QDataStream &operator >>(QDataStream &in, hShakeAckPkt &hand_shake_pkt)
    {
    in >> hand_shake_pkt.Id;
    in >> hand_shake_pkt.BlockSize;
     
    for(int i = 0; i < 2; ++i)
    in >> hand_shake_pkt.Reserved1[i];
     
    in >> hand_shake_pkt.FeedType;
     
    for(int i = 0; i < 3; ++i)
    in >> hand_shake_pkt.Reserved2[i];
     
    in >> hand_shake_pkt.Major;
    in >> hand_shake_pkt.Minor;
     
    for(int i = 0; i < 21; ++i)
    in >> hand_shake_pkt.ProgramId[i];
     
    return in;
    }

Now i want to know that, is there any other fastest way to read all the data in structure memory. (With or without QDataStream)

?????

I'll certainly happy to see that too But I'm worried that with QDataStream there is no other way to do serialization/deserialization without going after each item of the struct. Now about without the QDataStream, maybe this article will do the trick (depending in which direction you want to do it: http://smartqt.blogspot.com/2014/05/...-and-from.html).
