27   * 7.8.1 Macros for format specifiers
28   *
29   * Each of the following object-like macros expands to a string
30   * literal containing a conversion specifier, possibly modified by
31   * a prefix such as hh, h, l, or ll, suitable for use within the
32   * format argument of a formatted input/output function when
33   * converting the corresponding integer type.  These macro names
34   * have the general form of PRI (character string literals for the
35   * fprintf family) or SCN (character string literals for the fscanf
36   * family), followed by the conversion specifier, followed by a
37   * name corresponding to a similar typedef name.  For example,
38   * PRIdFAST32 can be used in a format string to print the value of
39   * an integer of type int_fast32_t.
