How to get non null terminated data out of a QByteArray ?

[Curtwagner1984]

Hello!

I'm trying to serialize a struct and send it over the network using QTcpsocket. I've run into a problem where I can't figure out how to extract raw data out of a QBytearray instance.

Here's a struct defenition:

typedef struct __attribute__((packed, aligned(4)))
{
    quint16 checksum1;
    quint16 checksum2;

}MyStruct;

And this is my test case:

    MyStruct sendingStruct;

    sendingStruct.checksum1 = 25;
    sendingStruct.checksum2 = 34;

    char b[sizeof(sendingStruct)];
    memcpy(b,&sendingStruct,sizeof(sendingStruct)); //b="\031\000"\000" after memcpy (in debugger)

    QByteArray ba = QByteArray::fromRawData(b,sizeof(b)); //ba="\031\000"\000" (in debugger)

    char *c = ba.data(); // c= "\031" (in debugger)  <= **The problem is here**

    MyStruct receivingStruct;

    memcpy(&receivingStruct, &c, sizeof(receivingStruct));

    qDebug() << QObject::tr("receivingStruct.checksum1 = %1, receivingStruct.checksum2 = %2").arg(receivingStruct.checksum1).arg(receivingStruct.checksum2);
    // output receivingStruct.checksum1 = 65108, receivingStruct.checksum2 = 121

How can I get the raw data from QByteArray without it terminating at the first null character it sees?

No it's not, it's here: memcpy(&receivingStruct, &c, sizeof(receivingStruct)); change &c to c or ba.constData(). &c is of type char**

@VRonin Indeed! Thank you!
