intmax_t(3type) intmax_t(3type)
intmax_t, uintmax_t - greatest-width basic integer types
Standard C library (libc)
#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 ## /* ... */
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.
C11, POSIX.1-2008.
C99, POSIX.1-2001.
The following header also provides these types: <inttypes.h>.
These types may not be as large as extended integer types, such
as __int128
int64_t(3type), intptr_t(3type), printf(3), strtoimax(3)
