Function stopping a function

[Sorin Schwimmer]

Hi All,

We all know that a function can launch the execution
of another function. How can a function stop the
execution of another function?

For instance, lenghty_function() executes, when an
external event triggers cancel(), which is supposed to
abruptly stop lengthy_function(), reset some variables
and exit immediately.

Thanks for your advice
SxN
