       typedef /* ... */  ptrdiff_t;

DESCRIPTION         top

       Used for a count of elements, or an array index.  It is the
       result of subtracting two pointers.  It is a signed integer type
       capable of storing values in the range [PTRDIFF_MAX,
       PTRDIFF_MAX].

       The length modifier for ptrdiff_t for the printf(3) and the
       scanf(3) families of functions is t, resulting commonly in %td or
       %ti for printing ptrdiff_t values.
