// 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:

// 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".
