Panels are ncurses(3NCURSES) windows with the added feature of depth.
Panel functions allow the use of stacked windows and ensure the proper
portions of each window and the curses stdscr window are hidden or dis-
played when panels are added, moved, modified or removed. The set of
currently visible panels is the stack of panels. The stdscr window is
beneath all panels, and is not considered part of the stack.
A window is associated with every panel. The panel routines enable you
to create, move, hide, and show panels, as well as position a panel at
any desired location in the stack.
Panel routines are a functional layer added to ncurses(3NCURSES), make
only high-level curses calls, and work anywhere terminfo curses does.
allocates a PANEL structure, associates it with win, places
the panel on the top of the stack (causes it to be displayed
above any other panel) and returns a pointer to the new panel.
refreshes the virtual screen to reflect the relations between
the panels in the stack, but does not call doupdate() to refresh
the physical screen. Use this function and not wrefresh or
wnoutrefresh. update_panels() may be called more than once
before a call to doupdate(), but doupdate() is the function
responsible for updating the physical screen.

puts the given visible panel on top of all panels in the stack.
See COMPATIBILITY below.
puts panel at the bottom of all panels.
moves the given panel window so that its upper-left corner is at
starty, startx. It does not change the position of the panel in
the stack. Be sure to use this function, not mvwin(), to move a
replaces the current window of panel with window (useful, for
example if you want to resize a panel; if you're using ncurses,
you can call replace_panel on the output of wresize(3NCURSES)).
It does not change the position of the panel in the stack.
returns a pointer to the panel above pan. If the panel argument
is (PANEL *)0, it returns a pointer to the bottom panel in the
returns a pointer to the panel just below pan. If the panel
argument is (PANEL *)0, it returns a pointer to the top panel in
sets the panel's user pointer.
returns the user pointer for a given panel.
returns a pointer to the window of the given panel.
Each routine that returns a pointer returns NULL if an error occurs.
Each routine that returns an int value returns OK if it executes suc-
cessfully and ERR if not.
Reasonable care has been taken to ensure compatibility with the
native panel facility introduced in SVr3.2 (inspection of the SVr4
manual pages suggests the programming interface is unchanged). The
PANEL data structures are merely similar. The programmer is cautioned
not to directly use PANEL fields.
The functions show_panel() and top_panel() are identical in this imple-
mentation, and work equally well with displayed or hidden panels. In
