Convert Union to QByteArray and vice-versa using QUdpSocket in Qt

devillIsHeree

I have one Union like below

#define no_of_bits 240
#define word_size 16

struct bits
{
    unsigned short int bit1:1;
    unsigned short int bit2:1;
    unsigned short int bit3:1;
    unsigned short int bit4:1;
    unsigned short int bit5:1;
    unsigned short int bit6:1;
    unsigned short int bit7:1;
    unsigned short int bit8:1;
    unsigned short int bit9:1;
    unsigned short int bit10:1;
    unsigned short int bit11:1;
    unsigned short int bit12:1;
    unsigned short int bit13:1;
    unsigned short int bit14:1;
    unsigned short int bit15:1;
    unsigned short int bit16:1;
};

union myData
{
        unsigned short int data[no_of_bits/word_size];
        struct bits word[no_of_bits/word_size];
};

I want to convert myData union into a QByteArray so that I can send it through socket using QUdpSocket using writeDatagram() function. So first tell me how can I convert this into QByteArray.

Next thing is that, On the receiver side how can I convert the QByteArray into the this Union myData again.
In short I want to convert this union myData into QByteArray so that I can send this over a network using QUdpSocket and on the receiver side reconvert this received QByteArray into the Union again.

At the end of the day, your struct/union is a bunch of bytes. https://doc.qt.io/qt-5/qbytearray.html#QByteArray-1 and https://doc.qt.io/qt-5/qbytearray.html#constData let you swap between QByteArray and const char *. The rest is just casting. I am assuming both sides have same architecture, compilers etc.; if not, that is a separate matter, but you don't ask about that,
