explicit-page-height

Arguments: window-or-widget

Returns the page-height that has been explicitly specified for window-or-widget with either the (setf page-height) function or the :page-height initarg.

If page-height has not been explicitly specified, then nil is returned.

(The function page-height, on the other hand, always returns the actual effective height that is in use.)

See also default-page-height. (And page-width, explicit-page-width and default-page-width.)
