QDataStream and readBytes

[pdoria]

Hi,

In the wake of this thread thread I'm trying to read binary data from a socket, hence the code:

unsigned int totalBytes = 0;
	totalBytes = tcpSocket.bytesAvailable();
	if (totalBytes < 4) return;		// bogus tx...
 
	uint headerSize=sizeof(uint);
	char * header = new char [headerSize];
 
	uint headerBytes=0;
	QDataStream inData(&tcpSocket);
 
	inData.readBytes(header, headerSize);
	headerBytes=atoi(header);

unsigned int totalBytes = 0;
	totalBytes = tcpSocket.bytesAvailable();
	if (totalBytes < 4) return;		// bogus tx...

	uint headerSize=sizeof(uint);
	char * header = new char [headerSize];

	uint headerBytes=0;
	QDataStream inData(&tcpSocket);

	inData.readBytes(header, headerSize);
	headerBytes=atoi(header);

To copy to clipboard, switch view to plain text mode 

Unless I really don't know what I'm doing... (most probably) why does inData.readBytes(header, headerSize); always cause a segfault?

Any pointers welcome.
Thanks in advance,
Pedro Doria Meunier.
