this depends upon _which_ standard libraries one uses :-)
i recommend the package_libs(.tar.gz) bundle from ''richardc''.

it has better functions, more consistent names and is built with the 
following conventions:

''    Return values in general

        - A function should *not* return wrapped values like
          {ok,Value}/{error,Reason} to indicate success or
          failure. The assumed behaviour should be success,
          and failures should be signalled by exceptions,
          as described below.

        - A function which is evaluated for its side effects
          only should always return the atom 'ok'; this is
          the typical Erlang "void" value.
