intmax_t(3type)                                                intmax_t(3type)

NAME
       intmax_t, uintmax_t - greatest-width basic integer types

LIBRARY
       Standard C library (libc)

SYNOPSIS
       #include <stdint.h>

       typedef /* ... */ intmax_t;
       typedef /* ... */ uintmax_t;

       #define INTMAX_WIDTH  /* ... */
       #define UINTMAX_WIDTH INTMAX_WIDTH

       #define INTMAX_MAX    /*  2**(INTMAX_WIDTH - 1) - 1  */
       #define INTMAX_MIN    /*  - 2**(INTMAX_WIDTH - 1)    */
       #define UINTMAX_MAX   /*  2**UINTMAX_WIDTH - 1       */

       #define INTMAX_C(c)   c ## /* ... */
       #define UINTMAX_C(c)  c ## /* ... */

DESCRIPTION
       intmax_t is a signed integer type capable of representing any value of
       any basic signed integer type supported by the implementation.  It is
       capable of storing values in the range [INTMAX_MIN, INTMAX_MAX].

       uintmax_t is an unsigned integer type capable of representing any value
       of any basic unsigned integer type supported by the implementation.  It
       is capable of storing values in the range [0, UINTMAX_MAX].

       The macros [U]INTMAX_WIDTH expand to the width in bits of these types.

       The macros [U]INTMAX_MAX expand to the maximum value that these types
       can hold.

       The macro INTMAX_MIN expands to the minimum value that intmax_t can
       hold.

       The macros [U]INTMAX_C() expand their argument to an integer constant
       of type [u]intmax_t.

       The length modifier for [u]intmax_t for the printf(3) and the scanf(3)
       families of functions is j; resulting commonly in %jd, %ji, %ju, or %jx
       for printing [u]intmax_t values.

STANDARDS
       C11, POSIX.1-2008.

HISTORY
       C99, POSIX.1-2001.

NOTES
       The following header also provides these types: <inttypes.h>.

BUGS
       These types may not be as large as extended integer types, such as
       __int128
