Documentation

Return the last buffer in FRAME's buffer list.

If BUFFER is the last buffer, return the preceding buffer instead. Buffers not visible in windows are preferred to visible buffers, unless optional argument VISIBLE-OK is non-nil. Optional third argument FRAME nil or omitted means use the selected frame's buffer list. If no such buffer exists, return the buffer *scratch*, creating it if necessary.
