You wrote: > (while true > (with-open [pipe (new java.io.FileInputStream pipe-name)] > (print pipe) > (let [buffer (make-array Byte/TYPE buffer-size)] > (. pipe read buffer) > (map print buffer)))) You're asking for the pipe to be repeatedly opened, one uninterrupted glob of bytes read and processed and then the pipe closed. Is that really what you intend? As written, this suggest a kind of "daemon" that monitors the pipe, waiting for successive writers, each of which must write everything they want processed by the far side in a single write call and furthermore that transmission must not exceed the operating system's pipe high-water mark. All this seems a bit fragile to me. But more practically, you should _say_ what you want your code to accomplish. > > (explanations snipped) > > Thanks for the explanations, the blocking is not a problem. ... It was not clear whether or not your mention of the blocking behavior was something you considered unexpected or problematic. > Vlad Randall Schulz --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
