(chunga:peek-char* stream &optional eof-error-p eof-value) | Function: We're simulating PEEK-CHAR by reading a character and putting it into *CHAR-BUFFER*.
|
(trivial-gray-streams:stream-peek-char stream) | Function: This is used to implement PEEK-CHAR; this corresponds to PEEK-TYPE of NIL. It returns either a character or :EOF. The default method calls STREAM-READ-CHAR and STREAM-UNREAD-CHAR.
