The touchline() function marks
    count lines starting from start
    in window win as having been modified. These
    characters will be synced to the terminal on the next call to
    wrefresh().
The touchoverlap() function marks the
    portion of win2 that overlaps
    win1 as being modified.
The touchwin() function marks the entire
    window win as having been modified. Conversely, the
    untouchwin() function marks the window
    win as being unmodified, so that any changes made to
    that window will not be synced to the terminal during a
    wrefresh().
The wtouchln() function performs one of
    two operations on n lines starting at
    line in the given window. If
    changed is 1 then the given line range is marked as
    being modified, if changed is 0 then the given line
    range is set to being unmodified.
The is_linetouched() function returns
    TRUE if line in window
    win has been modified since the last refresh was done,
    otherwise FALSE is returned.
is_wintouched() returns
    TRUE if the window win has
    been modified since the last refresh, otherwise
    FALSE is returned.
The redrawwin() function marks the entire
    window win as having been corrupted. Is is equivalent
    to the touchwin() function.
The wredrawln() function marks
    n lines starting at line in the
    given window as corrupted. It is equivalent to
    wtouchln(win,
    line, n,
    1).
The syncok() function determines whether
    all the ancestors of the specified window are implicitly touched whenever
    there is a change in the window. The initial state is
    FALSE.
The wsyncup() function touches all
    ancestors of win.
The wsyncdown() function touches
    win if any of its ancestors is touched.
NULL if an
  error is detected. The functions that return an int will return one of the
  following values:
