| // To print a 64-bit value in a portable way: |
| // int64_t value; |
| // printf("xyz:%" PRId64, value); |
| // The "d" in the macro corresponds to %d; you can also use PRIu64 etc. |
| // |
| // For wide strings, prepend "Wide" to the macro: |
| // int64_t value; |
| // StringPrintf(L"xyz: %" WidePRId64, value); |
| // |
| // To print a size_t value in a portable way: |
| // size_t size; |
| // printf("xyz: %" PRIuS, size); |
| // The "u" in the macro corresponds to %u, and S is for "size". |
