NAME

inttypes — fixed-size integer data types

SYNOPSIS

#include <inttypes.h>

DESCRIPTION

This header file defines integer data types of various sizes. By using the data types defined in this header file, developers can be assured that the data types will have the same properties and behavior on different systems.

Since not all implementations are required to support all of the integer sizes defined in this manual page, the proper way to see if a particular size of an integer is supported on the current implementation is to test the symbol that defines its maximum value. For example, if #ifdef UINT64_MAX tests false, then that implementation does not support 64-bit unsigned signed integers.

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

This header file defines the following data type.

imaxdiv_t

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

The following macros can be used as formatting options with the printf() family of functions (see printf(3S)). These macros are used to select the correct formatting option for the integer data types defined earlier in this manual page.

PRId8 d print formatting option for int8_t PRId16 d print formatting option for int16_t PRId32 d print formatting option for int32_t PRId64 d print formatting option for int64_t PRIdMAX d print formatting option for intmax_t PRIdFAST8 d print formatting option for int_fast8_t PRIdFAST16 d print formatting option for int_fast16_t PRIdFAST32 d print formatting option for int_fast32_t PRIdFAST64 d print formatting option for int_fast64_t PRIdFAST d print formatting option for intfast_t PRIdLEAST8 d print formatting option for int_least8_t PRIdLEAST16 d print formatting option for int_least16_t PRIdLEAST32 d print formatting option for int_least32_t PRIdLEAST64 d print formatting option for int_least64_t PRIi8 i print formatting option for int8_t PRIi16 i print formatting option for int16_t PRIi32 i print formatting option for int32_t PRIi64 i print formatting option for int64_t PRIiFAST8 i print formatting option for int_fast8_t PRIiFAST16 i print formatting option for int_fast16_t PRIiFAST32 i print formatting option for int_fast32_t PRIiFAST64 i print formatting option for int_fast64_t PRIiLEAST8 i print formatting option for int_least8_t PRIiLEAST16 i print formatting option for int_least16_t PRIiLEAST32 i print formatting option for int_least32_t PRIiLEAST64 i print formatting option for int_least64_t PRIu8 u print formatting option for uint8_t PRIu16 u print formatting option for uint16_t PRIu32 u print formatting option for uint32_t PRIu64 u print formatting option for uint64_t PRIuMAX u print formatting option for uintmax_t PRIuFAST8 u print formatting option for uint_fast8_t PRIuFAST16 u print formatting option for uint_fast16_t PRIuFAST32 u print formatting option for uint_fast32_t PRIuFAST64 u print formatting option for uint_fast64_t PRIuFAST u print formatting option for uintfast_t PRIuLEAST8 u print formatting option for uint_least8_t PRIuLEAST16 u print formatting option for uint_least16_t PRIuLEAST32 u print formatting option for uint_least32_t PRIuLEAST64 u print formatting option for uint_least64_t PRIo8 o print formatting option for int8_t PRIo16 o print formatting option for int16_t PRIo32 o print formatting option for int32_t PRIo64 o print formatting option for int64_t PRIoMAX o print formatting option for intmax_t PRIoFAST8 o print formatting option for int_fast8_t PRIoFAST16 o print formatting option for int_fast16_t PRIoFAST32 o print formatting option for int_fast32_t PRIoFAST64 o print formatting option for int_fast64_t PRIoFAST o print formatting option for intfast_t PRIoLEAST8 o print formatting option for int_least8_t PRIoLEAST16 o print formatting option for int_least16_t PRIoLEAST32 o print formatting option for int_least32_t PRIoLEAST64 o print formatting option for int_least64_t PRIx8 x print formatting option for int8_t PRIx16 x print formatting option for int16_t PRIx32 x print formatting option for int32_t PRIx64 x print formatting option for int64_t PRIxMAX x print formatting option for intmax_t PRIxFAST8 x print formatting option for int_fast8_t PRIxFAST16 x print formatting option for int_fast16_t PRIxFAST32 x print formatting option for int_fast32_t PRIxFAST64 x print formatting option for int_fast64_t PRIoFAST x print formatting option for intfast_t PRIxLEAST8 x print formatting option for int_least8_t PRIxLEAST16 x print formatting option for int_least16_t PRIxLEAST32 x print formatting option for int_least32_t PRIxLEAST64 x print formatting option for int_least64_t PRIX8 X print formatting option for int8_t PRIX16 X print formatting option for int16_t PRIX32 X print formatting option for int32_t PRIX64 X print formatting option for int64_t PRIXFAST8 X print formatting option for int_fast8_t PRIXFAST16 X print formatting option for int_fast16_t PRIXFAST32 X print formatting option for int_fast32_t PRIXFAST64 X print formatting option for int_fast64_t PRIXLEAST8 X print formatting option for int_least8_t PRIXLEAST16 X print formatting option for int_least16_t PRIXLEAST32 X print formatting option for int_least32_t PRIXLEAST64 X print formatting option for int_least64_t

The following macros can be used as formatting options with the scanf() family of functions (see scanf(3S)). These macros are used to select the correct formatting option for the integer data types defined earlier in this manual page.

SCNd16 d scan formatting option for int16_t SCNd32 d scan formatting option for int32_t SCNd64 d scan formatting option for int64_t SCNdMAX d scan formatting option for intmax_t SCNi16 i scan formatting option for int16_t SCNi32 i scan formatting option for int32_t SCNi64 i scan formatting option for int64_t SCNiMAX i scan formatting option for intmax_t SCNu16 u scan formatting option for uint16_t SCNu32 u scan formatting option for uint32_t SCNu64 u scan formatting option for uint64_t SCNo16 o scan formatting option for int16_t SCNo32 o scan formatting option for int32_t SCNo64 o scan formatting option for int64_t SCNoMAX o scan formatting option for intmax_t SCNx16 x scan formatting option for int16_t SCNx32 x scan formatting option for int32_t SCNx64 x scan formatting option for int64_t SCNxMAX x scan formatting option for intmax_t SCNdFAST d scan formatting option for intfast_t SCNiFAST i scan formatting option for intfast_t SCNoFAST o scan formatting option for intfast_t SCNxFAST x scan formatting option for intfast_t

Notes

The formatting options for the printf() family of functions all begin with PRI, whereas the formatting options for the scanf() family of functions all begin with SCN. These formatting strings may not be interchangeable.

EXAMPLES

The following example shows how to use one of the print formatting options with the printf() function.

uint64_t u; ... printf("u = %016" PRIx64 "\n", u);
