Function notcurses_cursor_enable 

pub unsafe extern "C" fn notcurses_cursor_enable(
    nc: *mut notcurses,
    y: c_int,
    x: c_int,
) -> c_int

Enable or disable the terminal’s cursor, if supported, placing it at ‘y’, ‘x’. Immediate effect (no need for a call to notcurses_render()). It is an error if ‘y’, ‘x’ lies outside the standard plane. Can be called while already visible to move the cursor.
