| 31 | bool "Enable safe version of sprintf()" |
| 32 | help |
| 33 | Since sprintf() can overflow its buffer, it is common to use |
| 34 | snprintf() instead, which knows the buffer size and can avoid |
| 35 | overflow. However, this does increase code size slightly (for |
| 36 | Thumb-2, about 420 bytes). Enable this option for safety when |
| 37 | using sprintf() with data you do not control. |

| 42 | If this variable is defined, U-Boot is linked against the |
