Solved QDataStream "stopped working"
-
Hello,
I'm doing the following operation :
char firstQuery[512] = "{'command':'ask_session','version':'1.0','user_agent':'faf-client'}"; QByteArray *block; QDataStream *out = new QDataStream(block, QIODevice::ReadWrite); out->setVersion(QDataStream::Qt_5_10); uint length = (2*sizeof(firstQuery) + 4); qDebug() << length; out->writeBytes((const char*)firstQuery, length);
The next step would be to send this block into a socket.
But I have a problem : the last function call "writeBytes" causes the app to "Stop working" with no error messages.Am I doing something wrong ?

@rackover said in QDataStream "stopped working":
QByteArray *block;
dangling pointer
out->writeBytes((const char*)firstQuery, length);
out of bounds (
length>=std::extent<decltype(firstQuery)>::value
)
const QByteArray firstQuery ("{'command':'ask_session','version':'1.0','user_agent':'faf-client'}"); QByteArray block; QDataStream out (&block, QIODevice::ReadWrite); out.setVersion(QDataStream::Qt_5_10); out.write(firstQuery);
