In the sources of OpenFOAM we find

exit(FatalError);

as well as

abort(FatalError);

The definition of both functions in $FOAM_SRC/OpenFOAM/db/error/error.C seems very similar to me. So maybe I am missing something.

Is there a rule of thumb when to use which?

What I already can tell is this:

• Abort prints the call stack
• Exit always returns 1 as return value to the Terminal (check with

  echo $?

  )
