Are you sure? A little googling picks up e.g. HP docs [1] that state RETURN VALUE If the aiocb is invalid or if no asynchronous I/O operation is enqueued for the aiocb, aio_error() returns -1 and errno is set to indicate the error It may be non-POSIX, but I'd like to see some verbiage for which HP/UX's behavior isn't the most natural interpretation. jcc [1] http://docs.hp.com/en/B9106-90009/aio_error.2.html _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
