Hello Thiago, Actually I just find out that the C function which I am calling in Qt, is creating a thread. I do not have any control over this thread. The library I am using that have callback interface and whenever data available it calls my callback method in Qt.
So, in order to solve this problem, what should I do? By the way, my application does not crash so I don't have backtrace. Thank you in advance.
