CHAPTER 15. EXTENDED STREAM OUTPUT

The end-of-page action is one of:

:wrap - when doing text output, wrap the text around (that is, go back to the top of the
viewport).
:scroll - scroll the window vertically to keep the cursor position inside the viewport, then
keep doing output. This is the default.
:allow - ignore the viewport and do the output on the drawing plane beyond the visible
part of the viewport.

=> with-end-of-page-action (stream action) &body body [Macro]
Temporarily changes stream's end-of-page action for the duration of execution of body. action
must be one of the actions described in stream-end-of-page-action.
The stream argument is not evaluated, and must be a symbol that is bound to a stream. If
stream is t, *standard-output* is used. body may have zero or more declarations as its first
forms.

15.5 Attracting the User's Attention

=> beep &optional sheet [Generic Function]
Attracts the user's attention, usually with an audible sound.

15.6 Buffering of Output

Some mediums that support the output protocol may buffer output. When buffering is enabled
on a medium, the time at which output is actually done on the medium is unpredictable. force- outputor finish-output can be used to ensure that all pending output gets completed. If the
medium is a bidirectional stream, a force-output is performed whenever any sort of input is
requested on the stream.

with-buffered-output provides a way to control when buffering is enabled on a medium. By
default, CLIM's interactive streams are buffered if the underlying window system supports buffer-
ing.

=> medium-buffering-output-p medium [Generic Function]
Returns true if the medium medium is currently buffering output, otherwise returns false.

=> (setf medium-buffering-output-p) buffer-p medium [Generic Function]
Sets medium-buffering-output-p of the medium medium to buffer-p.
