@section The Buffer List
@cindex buffer list
- The @dfn{buffer list} is a list of all live buffers. The order of
-the buffers in the list is based primarily on how recently each buffer
-has been displayed in a window. Several functions, notably
address@hidden, use this ordering. A buffer list displayed for
-the user also follows this order.
-
- Creating a buffer adds it to the end of the buffer list, and killing
-a buffer removes it. Buffers move to the front of the list when they
-are selected for display in a window (@pxref{Displaying Buffers}), and
-to the end when they are buried (see @code{bury-buffer}, below).
-There are no functions available to the Lisp programmer which directly
-manipulate the buffer list.
-
- In addition to the fundamental Emacs buffer list, each frame has its
-own version of the buffer list, in which the buffers that have been
-selected in that frame come first, starting with the buffers most
-recently selected @emph{in that frame}. (This order is recorded in
address@hidden's @code{buffer-list} frame parameter; see @ref{Buffer
-Parameters}.) The buffers that were never selected in @var{frame} come
-afterward, ordered according to the fundamental Emacs buffer list.
