exit:exit in Framework Functions

• (exit:exit) -> any

  exit:exit performs four actions:

  • sets the result of the exit:exiting? function to #t.

  • invokes the exit-callbacks, with exit:can-exit?If none of the ``can?'' callbacks return #f,

  • invokes exit:on-exitand then

  • queues a callback that calls exit (a mzscheme procedure) and (if exit returns) sets the result of exit:exiting? back to #t.
