NAME
     inttypes.h, inttypes - fixed size integer types

SYNOPSIS
     #include 


DESCRIPTION
     The  header includes the  header.


     The  header includes a definition of the follow-
     ing 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  charac-
     ter string literal containing a conversion specifier, possi-
     bly 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
     . In these names, N represents the  width  of  the
     type as described in . 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
     , the corresponding fprintf() and  fwprintf() mac-
     ros  must  be  defined.  The  corresponding   fscanf()   and
     fwscanf()  macros must be defined as well, unless the imple-
     mentation does not have a suitable modifier for the type.

USAGE
     The purpose of  is to provide a set  of  integer
     types  whose  definitions are consistent across machines and
     independent of operating 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 sup-
     port. Consistent use of this header  greatly  increases  the
     portability of applications across platforms.

EXAMPLES
     Example 1 Use of Macro


     The following code uses one of the macros available  through
     .


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