| Allegro CL version 8.2 Unrevised from 8.1 to 8.2. 8.1 version |
Arguments: character-input-stream
This is used to implement read-char-no-hang. It returns either a
character, or nil
if no input is currently
available, or :eof
if end-of-file is reached. The default
method provided by fundamental-character-input-stream
simply
calls stream-read-char; this
is sufficient for file streams, but interactive streams should define
their own method.
See also streams.htm for general information on streams in Allegro CL.
