Question

Mathematica has the CheckAbort function which allows to catch and handle user-generated and programmatic Aborts. But it does not allow to catch interrupts generated by such functions as TimeConstrained and MemoryConstrained:

TimeConstrained[CheckAbort[Pause[100], Print["From CheckAbort"]], 1]

(does not print "From CheckAbort").

Is there a way to catch such interrupts in Mathematica?

EDIT: I do know that third argument of TimeConstrained and MemoryConstrained allows to evaluate some code in the case of interrupt but this way is not what I need: I need a way to handle such interrupts entirely inside of my function allowing a user do not care of its internals.

P.S. The reason why I need this is that I have a function that creates MathLink objects which must be closed in the case of any interrupts or aborts but not in other cases.

Answer 1

The construct for this is available in undocumented form.

Internal`WithLocalSettings[
  preprocessing,
  code,
  postprocessing]

will cause postprocessing to take place before returning from aborts or various types of jumps.
