Arguments: stream character
Undoes the last call to stream-read-char, as in unread-char. Returns nil. Every subclass of fundamental-character-input-stream must define
a method for this function. As with
unread-char,
only one character may be returned to the builtin stream classes.
See also streams.htm for general information on streams in Allegro CL.
