Function atexit and Ctrl+C

[Pavel Hofman]

Hi,

I am trying to run atexit in a script started in octave command of the 
GUI environment. I stop the script with Ctrl+C, please is there a way to 
run a function at such moment? Ctrl+C seems to skip the atexit feature.

Reason: my script opens a figure and I want to close the figure when the 
script ends in GUI command.

Octave 4.2, linux

Thanks lot in advance.

Best regards,

Pavel.
