How to disable creation of qt temporary files

I have a Qt embedded application that uses an ini file for storage of configuration information. I have modified the power on/off management of this file to reduce corruption if power is abruptly interrupted. My testing includes cycling power every 2 minutes with a variable on to off duty cycle to simulate random power failures. I have minimized corruption of my ini file but have noticed a number of qt_temp.xxxx files after days of testing. How do I disable these file from being created. I am using QFile classes as well as QSettings classes.
Thanks,

You would have to remove all functionality from Qt which makes use of these files or simply have them created in a ramdisk.
