Hi all,
why the Unix.getlogin function returns "no such file or directory"
if the unix getlogin() function returns null (see getlogin.c) ? 

ex:
-----------
let main () =
  try
      print_string (Unix.getlogin())
  with Unix.Unix_error(e,_,_) ->
      failwith (Unix.error_message e)
;;

main ()
---------

echo "a" | ./a.out
Fatal error: exception Failure(No such file or directory")

How can I use getlogin if I want to pass something on the standard input
to my program ? 

The same example works with MacOsX. Why this difference ?

:)
