| 1730 | |
| 1731 | *** WARNING *** |
| 1732 | |
| 1733 | The format should limit the total size of the formatted output string to |
| 1734 | 1000 bytes. In particular, this means that no unrestricted "%s" formats |
| 1735 | should occur; these should be limited using "%.<N>s where <N> is a |
| 1736 | decimal number calculated so that <N> plus the maximum size of other |
| 1737 | formatted text does not exceed 1000 bytes. Also watch out for "%f", |
| 1738 | which can print hundreds of digits for very large numbers. |
