I did so at first, but it didn't work with Visual Studio 2010 at hand. It doesn't support %z which is added in C99.

But "I" (capital i) instead of "ll" seems appropriate as the following page says. I chose this.

I For signed integer types, causes printf to expect ptrdiff_t-sized integer argument; for unsigned integer types, causes printf to expect size_t-sized integer argument. Commonly found in Win32/Win64 platforms.
