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