ncurses_raw() places the terminal in raw mode. Raw mode is similar to cbreak mode, in that characters typed are immediately passed through to the user program. The differences that are that in raw mode, the interrupt, quit, suspend and flow control characters are all passed through uninterpreted, instead of generating a signal. Returns TRUE if any error occurred, otherwise FALSE.
