Hi Alex, http://www.software-lab.de/refP.html#poll says:
(poll 'cnt) -> cnt | NIL Checks for the availability of data for reading on the file descriptor cnt. See also open, in and close. : (and (poll *Fd) (in @ (read))) # Prevent blocking The comment is a bit misleading as it does not prevent blocking really. The data might be available but the 'read' function might still block. Cheers, Tomas -- UNSUBSCRIBE: mailto:[EMAIL PROTECTED]
