/* "The following macros shall be defined. Each expands to a character string
* literal containing a conversion specifier, possibly modified by a lengt
* 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.
