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