That's not good approach. The size differs on 32-bit platforms (ix86)

You should use "%zd" for size_t variable
and "%zu" for ssize_t variable.

@see man 3 printf -> The length modifier

But IIRC the most important part is "z" modifier and warning is not printed
if number is unsigned or not ("d" or "u"). So you can use either "%zd" or "%zu"
for size_t and ssize_t variables
