Function ncursesw::halfdelay

pub fn halfdelay(tenths: Duration) -> Result<(), NCurseswError>

Used for half-delay mode, which is similar to cbreak mode in that characters typed by the user are immediately available to the program. However, after blocking for tenths tenths of seconds, raise an exception if nothing has been typed. The value of tenths must be a number between 1 and 255. Use nocbreak() to leave half-delay mode.
