The touchwin and touchline routines throw away all optimization information about which parts of the window have been touched, by pretending that the entire window has been drawn on. It is sometimes necessary to call these routines when using overlapping windows. In this case, a change to one window affects the other window, but the other window's records of which lines have been changed do not reflect the change in the first window. The touchline routine only pretends that count lines have been changed, beginning with line start.
The untouchwin routine marks all lines in the window as unchanged since the last call to wrefresh.
The wtouchln routine makes n lines in the window, starting at line y, look as if they have changed (if changed=1) or have not changed (changed=0) since the last call to wrefresh.

wrefresh; otherwise they

All routines return the integer
failure and an integer value other than
successful completion, unless otherwise noted in the preceding routine descriptions.
