The newpad() function creates a new pad of
    size lines, cols.
subpad() is similar to
    newpad() excepting that the size of the subpad is
    bounded by the parent pad pad. The subpad shares
    internal data structures with the parent pad and will be refreshed when the
    parent pad is refreshed. The starting column and row
    begin_y, begin_x are relative to
    the parent pad origin.
The pnoutrefresh() function performs the
    internal processing required by curses to determine what changes need to be
    made to synchronise the internal screen buffer and the terminal but does not
    modify the terminal display. A rectangular area of the pad starting at
    column and row pbeg_y, pbeg_x is
    copied to the corresponding rectangular area of the screen buffer starting
    at column and row sbeg_y, sbeg_x
    and extending to smax_y,
  smax_x.
The prefresh() function causes curses to
    propagate changes made to the pad specified by pad to
    the terminal display. A rectangular area of the pad starting at column and
    row pbeg_y, pbeg_x is copied to
    the corresponding rectangular area of the terminal starting at column and
    row sbeg_y, sbeg_x and extending
    to smax_y, smax_x.
The pnoutrefresh() and
    doupdate() functions can be used together to speed
    up terminal redraws by deferring the actual terminal updates until after a
    batch of updates to multiple pads has been done.
The is_pad() function returns true if the
    given window was created by newpad(), otherwise
    false.
NULL if an
  error is detected. The functions that return an int will return one of the
  following values:
OKERRsubpad() function is similar to the
  derwin(3) function, and not the
  subwin(3) function.
is_pad() function is a ncurses
  extension to the Curses library and was added in NetBSD
  8.0.
