// 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".
