How do I Shut Down My Real-Time DLL in LabWindows/CVI?

Primary Software:
Primary Software Version: 8.0
Primary Software Fixed Version: N/A
Secondary Software: LabWindows/CVI Add-ons>>LabVIEW/CVI Real-Time Module

I am running a LabWindows/CVI DLL on a real-time target. Why does the Terminate Execution command or Stop button require a reboot of my machine?

Selecting the Terminate Execution command or Stop button from the LabWindows/CVI debugger cause program execution to stop immediately without running any cleanup code in the program. This may leave the real-time target in a bad state, which would then require a reboot.

Instead, you can call the RTIsShuttingDown library function from your program to check for a shut down request. From the LabWindows/CVI debugger, you can select the Simulate RT Shutting Down item from the <Running> menu to cause the RTIsShuttingDown library function to return true. This way your program can call any necessary cleanup code, leaving the real-time target in a good state.
