Function libnotcurses_sys::notcurses_inputready_fd

pub unsafe extern "C" fn notcurses_inputready_fd(n: *mut notcurses) -> c_int

Get a file descriptor suitable for input event poll()ing. When this descriptor becomes available, you can call notcurses_getc_nblock(), and input ought be ready. This file descriptor is not necessarily the file descriptor associated with stdin (but it might be!).
