#ifndef BASE_FORMAT_MACROS_H_

#define BASE_FORMAT_MACROS_H_

// 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".
