QDataStream and readBytes

[pdoria]

Ok. last step:

this doesn't work...

quint16 dataLength=0;
 
QDataStream inData(&tcpSocket);
 
while (zerocount < 4 && dataLength==0)
{
	inData >> dataLength;
	if (dataLength==0) zerocount++;
}
 
// exceed number of tries... bogus txs. return.
if (zerocount==3) return;
 
char * data = new char[dataLength];
inData >> data;

quint16 dataLength=0;

QDataStream inData(&tcpSocket);

while (zerocount < 4 && dataLength==0)
{
	inData >> dataLength;
	if (dataLength==0) zerocount++;
}

// exceed number of tries... bogus txs. return.
if (zerocount==3) return;

char * data = new char[dataLength];
inData >> data;

To copy to clipboard, switch view to plain text mode 

the data is always 0x0 ...
So ... please tell me... after in >> dataLength the pointer in the stream is advanced or not?
the operator>> ( char *& s ) is able to convert the binary data into char?

Thanks in advance.

bump.

Must one do this?

char * data = new char[dataLength];
	qint8 c;
	int n;
	for (n=0; n<dataLength; n++) {
		inData >> c;
		data[n]=c;
	}

char * data = new char[dataLength];
	qint8 c;
	int n;
	for (n=0; n<dataLength; n++) {
		inData >> c;
		data[n]=c;
	}

To copy to clipboard, switch view to plain text mode 

It feels a bit archaic...

No, you can use readRawData() instead.

Be aware that QDataStream is not a general purpose binary stream but a serialization method. Don't use it if you don't need it.
