Function ncursesw::touchline

pub fn touchline(
    handle: WINDOW, 
    count: i32, 
    start: i32
) -> Result<(), NCurseswError>

Pretend that count lines have been changed, beginning with line start.

This 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. This is sometimes necessary when using overlapping windows, since a change to one window affects the other window, but the records of which lines have been changed in the other window do not reflect the change.
