/* IDX_MAX is the maximum value of an idx_t. */
#define IDX_MAX PTRDIFF_MAX
+/* A printf/scanf length modifier for idx_t. For example, if i is an idx_t,
+ printf ("i = %"pIDX"d\n", i) outputs i's value. */
+#define pIDX "t"
+
/* So far no need has been found for an IDX_WIDTH macro.
Perhaps there should be another macro IDX_VALUE_BITS that does not
count the sign bit and is therefore one less than PTRDIFF_WIDTH. */
