Once you've returned either success or failure (the only two choices) to
the operating system, yes, the OS does whatever it wants, e.g. print a
message saying "that was a good program" or "that was a bad
program".

RM> From your other reply, I gather that it's rash to make any

0 = success, EXIT_SUCCESS = success, EXIT_FAILURE = failure.

RM> I should be able to use anything, within sensible limits, provided

NO.  ANYTHING ELSE IS A BUG.

RM> I doc it properly.

If you want to document that your program is broken, yes, that makes a
small amount of sense.  (So long as you're drunk, and thus have an excuse).
