Package

Signature

output-pane-cached-display-user-info pane => user-info

Values

user-info

A Lisp object.

Description

The function output-pane-cached-display-user-info gets and sets the user-info in the current cached display of the output pane pane .

If pane does not have a cached display, the getter returns nil and the setter has no effect (but returns the new user-info as per normal Common Lisp conventions).

A value that is set by the setter will be returned by the getter until the cached display is freed by a call to output-pane-free-cached-display, either explicitly or implicitly. Note that this means that calls to start-drawing-with-cached-display and output-pane-cache-display also reset the user-info .
