I'm using some threads (QThread) in my app, and I have issues under
windows, but all works fine on linux.
As I'm accessing some common resources (typically I access the same
hardware from different threads, through the same bus), I use a QMutex.
The bus driver, which is common to all threads, as 2 methods: acquireBus()
and releaseBus(), calling the lock() and unlock() mutex methods. Then, in
the threads, I call these bus driver methods in a try/finally statement.
The code is here:
My question is: are there some different behaviour between linux and
windows about QThread and QMutex? IS it better to use a QMutexLocker
instead of a QMutex? I don't think so, as the try/finally statement ensure
that the unlock() method is always called...
