// This file defines the format macros for some integer types.

// 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".
