Exit

The exiting library provides a way to perform cleanup actions when the application is quit.

Clean up actions can be installed by registering a callback procedure that will be invoked by exit:exit.

On exit, callback will be called with no arguments. Also, use exit:insert-on-callback:

  (exit:insert-on-callback callback) 

Also, callbacks can be registered that abort exiting. To install such a a callback, use exit:insert-can?-callback:

  (exit:insert-can?-callback callback)
