My C application is returning 0xE0434352 to Windows Task Scheduler but it is not crashing

Question

I have written a few C  apps that I have running via windows task scheduler  They are running successfully  as I can see from the log files that they are writing   but windows task scheduler shows them returning a last run result of 0xE0434352  Is there something I need to do in my C  application so that it returns a success code to the windows task scheduler
