Function ncursesw::intrflush

pub fn intrflush(handle: WINDOW, flag: bool) -> Result<(), NCurseswError>

If the intrflush() option is enabled (flag is true), and an interrupt key is pressed on the keyboard (interrupt, break, quit), all output in the tty driver queue will be flushed, giving the effect of faster response to the interrupt, but causing NCurses to have the wrong idea of what is on the screen. Disabling the option (flag is false) prevents the flush. The default for the option is inherited from the tty driver settings. The window argument is ignored.
