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
C99 and later; POSIX.1-2001 and later.
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
