(chunga:read-char* stream &optional eof-error-p eof-value) | Function: The streams we're dealing with are all binary with element type (UNSIGNED-BYTE 8) and we're only interested in ISO-8859-1, so we use this to `simulate' READ-CHAR.
|
(trivial-gray-streams:stream-read-char stream) | Function: Read one character from the stream. Return either a character object, or the symbol :EOF if the stream is at end-of-file. Every subclass of FUNDAMENTAL-CHARACTER-INPUT-STREAM must define a method for this function.
|
(trivial-gray-streams:stream-unread-char stream character) | Function: Un-do the last call to STREAM-READ-CHAR, as in UNREAD-CHAR. Return NIL. Every subclass of FUNDAMENTAL-CHARACTER-INPUT-STREAM must define a method for this function.

(read-char-no-hang &optional (stream *standard-input*) (eof-error-p t) eof-value recursive-p) | Undocumented
|
| Mentioned in: CLtL2 - 22.2.1. Input from Character Streams HyperSpec - Function READ-CHAR-NO-HANG Successful Lisp - chapter19 | |
(trivial-gray-streams:stream-read-char-no-hang stream) | Function: 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.
