[SOLVED] How to pass QDataStream between functions?
-
Hi
I have two functions, A and B. An instance of QDataStream is created in A and it should be passed to B so B can write some data on it. After passing a stream by reference, it seems that it's not valid anymore.
What do you suggest?
@
void A() {
QDataStream x;
// ...
B(x);
}void B (QDataStream& d)
{
// Do something with d
}

What do you mean with 'not valid anymore' ?

QDataStream::status() returns QDataStream::ReadCorruptData

That has nothing to do with passing QDataStream as a reference. QDataStream doesn't even know how it's passed or that it has been passed.
You have a problem in your actual data streaming operations (or the file you're trying to read really is corrupt). -
Indeed. A QDataStream can be passed by reference just fine. However, you should probably avoid storing that reference and then re-using it later on.

Oops
An incorrect counter in loop caused to seek out of file. This was a really disappointing effort for me :( I'm struggling to solve this for a couple of days, but I even can't see such a simple bug.
