newt_wait_for_key — Doesn't return until a key has been pressed
This function doesn't return until a key has been pressed. The keystroke is then ignored. If a key is already in the terminal's buffer, this function discards a keystroke and returns immediately.
- newt_clear_key_buffer() - Discards the contents of the terminal's input buffer without waiting for additional input
