| michael@0 | 12 | * nsPrintfCString lets you create a nsCString using a printf-style format |
| michael@0 | 13 | * string. For example: |

| michael@0 | 15 | * NS_WARNING(nsPrintfCString("Unexpected value: %f", 13.917).get()); |
| michael@0 | 16 | * |
| michael@0 | 17 | * nsPrintfCString has a small built-in auto-buffer. For larger strings, it |
| michael@0 | 18 | * will allocate on the heap. |
