Arguments: input-stream
Used by listen. Returns true or false. The default method uses stream-read-char-no-hang and stream-unread-char. Most streams should define their own method since it will usually be trivial and will always be more efficient than the default method.
See also streams.htm for general information on streams in Allegro CL.
