/* "The following macros shall be defined. Each expands to a character string

* modifier, suitable for use within the format argument of a formatted
* input/output function when converting the corresponding integer type.
* These macros have the general form of PRI (character string literals for
* the fprintf() and fwprintf() family of functions) or SCN (character
* string literals for the fscanf() and fwscanf() family of functions),
* followed by the conversion specifier, followed by a name corresponding
* to a similar type name in <stdint.h>. In these names, N represents the
* width of the type as described in <stdint.h>. For example, PRIdFAST32
* can be used in a format string to print the value of an integer of type
* int_fast32_t.
