I almost complete my task to porting application, it should be no problem using same command in qnx4 and also in qnx6 but otherwise it happen.
My QNX4 application using system(“rtc -s at”); to set Bios clock and its work very well. Unfortunately, using same syntax in my new application on QNX6,the OS says"rtc: -b base addr must be specified for mc146818 clock type" . Can you all show me how to porting this command? Why should we specificly tell the OS what is base addr for RTC?
