| // The arraysize(arr) macro returns the # of elements in an array arr. |
| // The expression is a compile-time constant, and therefore can be |
| // used in defining new arrays, for example. If you use arraysize on |
| // a pointer by mistake, you will get a compile-time error. |
| // |
| // One caveat is that, for C++03, arraysize() doesn't accept any array of |
| // an anonymous type or a type defined inside a function. In these rare |
| // cases, you have to use the unsafe ARRAYSIZE() macro below. This is |
| // due to a limitation in C++03's template system. The limitation has |
| // been removed in C++11. |
