Add a size parameter to mode_string() and use scnprintf() to return only the bytes actually written. Add an early return when offset already exceeds the buffer. In show_modes(), stop accumulating once the buffer is full. Join the discussion | GCVE Database | 08/27/2026, 06:31:33 UTC Added: 08/27/2026, 15:12:58 UTC |
