NAME

       inttypes.h, inttypes - fixed size integer types

SYNOPSIS

       #include <inttypes.h>

DESCRIPTION

       The <inttypes.h> header includes the <stdint.h> header.

       The <inttypes.h> header includes a definition of the following type:

       imaxdiv_t       structure type that is the type of the value returned by the imaxdiv() function.

       The  following  macros  are  defined.  Each expands to a character string literal containing a conversion specifier, possibly modified by a
       length 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.

       The fprintf() macros for signed integers are:

       PRIdN  PRIdLEASTN  PRIdFASTN  PRIdMAX  PRIdPTR
       PRIiN  PRIiLEASTN  PRIiFASTN  PRIiMAX  PRIiPTR

       The fprintf() macros for unsigned integers are:

       PRIoN   PRIoLEASTN  PRIoFASTN  PRIoMAX  PRIoPTR
       PRIuN   PRIuLEASTN  PRIuFASTN  PRIuMAX  PRIuPTR
       PRIxN   PRIxLEASTN  PRIxFASTN  PRIxMAX  PRIxPTR
       PRIXN   PRIXLEASTN  PRIXFASTN  PRIXMAX  PRIXPTR

       The fscanf() macros for signed integers are:

       SCNdN  SCNdLEASTN  SCNdFASTN  SCNdMAX  SCNdPTR
       SCNiN  SCNiLEASTN  SCNiFASTN  SCNiMAX  SCNiPTR

       The fscanf() macros for unsigned integers are:

       SCNoN  SCNoLEASTN  SCNoFASTN  SCNoMAX  SCNoPTR
       SCNuN  SCNuLEASTN  SCNuFASTN  SCNuMAX  SCNuPTR
       SCNxN  SCNxLEASTN  SCNxFASTN  SCNxMAX  SCNxPTR

       For each type that the implementation provides in <stdint.h>, the corresponding fprintf() and  fwprintf() macros must be defined. The  cor-
       responding fscanf() and fwscanf() macros must be defined as well, unless the implementation does not have a suitable modifier for the type.

USAGE

       The  purpose of <inttypes.h> is to provide a set of integer types whose definitions are consistent across machines and independent of oper-
       ating systems and other implementation idiosyncrasies. It defines, with a typedef, integer types of various sizes. Implementations are free
       to typedef them as ISO C standard integer types or extensions that they support. Consistent use of this header greatly increases the porta-
       bility of applications across platforms.

EXAMPLES

       Example 1: Use of Macro

       The following code uses one of the macros available through <inttypes.h>.

       #include <inttypes.h>
       #include <wchar.h>
       int main(void)
       {
	    uintmax_t i = UINTMAX_MAX; // This type always exists.
	    wprintf("The largest integer value is %020"
		 PRIxMAX, "
", i);
	    return 0;
       }
