Hello Guy,
I trying to put a while(1) C function in my Qt project.
I want to run it in the background of a specific Gui.
I have been trying to use threads to do it .I tried declaring the thread in main() and my Gui cpp file(infuison.cpp) But there seem to be a problem.
this is what i have done.
QThread: Destroyed while thread is still running
ASSERT failure in QThread::setTerminationEnabled(): "Current thread was not started with QThread.", file thread\qthread_win.cpp, line 574
Invalid parameter passed to C runtime function.
