this makes no sense to me. opengroup says:
If unsuccessful, they shall return a value of -1 and set errno
to indicate the error.
so "-1" can not be a useful value by definition. clearly our
implementation needs to map between internal values and ones
we return to these functions if "-1" is interanlly useful.
it's also extremely awful to introduce more APIs that abuse errno
like you suggest, and should not be done any time.
