I'm not familiar with `sync/timeout' or `scheme_fd_to_semaphore', but from `sync/timeout's documentation: "A zero value for timeout is equivalent to (lambda () #f). In either case, each evt is checked at least once before returning #f or calling timeout." So, I guess it's not a surprise that your call always returns `#f'. It's not blocking/waiting, how one would want in this situation. ____________________ Racket Users list: http://lists.racket-lang.org/users
