Allegro CL version 8.2
Unrevised from 8.1 to 8.2.
8.1 version

stream-read-char-no-hang

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.
