pub fn touchwin(handle: WINDOW) -> Result<(), NCurseswError>Expand description
Pretend the whole window has been changed, for purposes of drawing optimizations.
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.
