+// 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". |
