NAME

stdint.h, stdint - integer types

SYNOPSIS

#include

DESCRIPTION

The header declares sets of integer types having

specified widths, and defines corresponding sets of macros. It also defines macros that specify limits of integer types corresponding to types defined in other standard headers. The ``width'' of an integer type is the number of bits used to store its value in a pure binary system; the actual type

can use more bits than that (for example, a 28-bit type

could be stored in 32 bits of actual storage). An N-bit

signed type has values in the range -2^N-1 or 1-2^N-1 to

2^N-1-1, while an N-bit unsigned type has values in the

range 0 to 2^N-1.

Types are defined in the following categories: o integer types having certain exact widths o integer types having at least certain specified widths o fastest integer types having at least certain specified widths o integer types wide enough to hold pointers to objects o integer types having greatest width Some of these types may denote the same type. Corresponding macros specify limits of the declared types and construct suitable constants.

For each type described herein that the implementation pro-

vides, the header declares that typedef name and

defines the associated macros. Conversely, for each type described herein that the implementation does not provide,

the header does not declare that typedef name,

nor does it define the associated macros. An implementation

provides those types described as required, but need not provide any of the others (described as optional). Integer Types When typedef names differing only in the absence or presence of the initial u are defined, they denote corresponding

signed and unsigned types as described in the ISO/IEC 9899: 1999 standard, Section 6.2.5; an implementation providing one of these corresponding types must also provide the other. In the following descriptions, the symbol N represents an unsigned decimal integer with no leading zeros (for example, 8 or 24, but not 04 or 048).

Exact-width integer types

The typedef name intN_t designates a signed integer type

with width N, no padding bits, and a two's-complement

representation. Thus, int8_t denotes a signed integer

type with a width of exactly 8 bits.

The typedef name uintN_t designates an unsigned integer

type with width N. Thus, uint24_t denotes an unsigned

integer type with a width of exactly 24 bits. The following types are required:

int8_t

int16_t

int32_t

uint8_t

uint16_t

uint32_t

If an implementation provides integer types with width 64 that meet these requirements, then the following types are required:

int64_t

uint64_t

In particular, this is the case if any of the following are true: o The implementation supports the

_POSIX_V6_ILP32_OFFBIG programming environment

and the application is being built in the _POSI

X_V6_ILP32_OFFBIG programming environment (see

the Shell and Utilities volume of IEEE Std

1003.1-200x, c99, Programming Environments).

o The implementation supports the

_POSIX_V6_LP64_OFF64 programming environment

and the application is being built in the

_POSIX_ V6_LP64_OFF64 programming environment.

o The implementation supports the

_POSIX_V6_LPBIG_OFFBIG programming environment

and the application is being built in the

_POSIX_V6_LPBIG_OFFBIG programming environment.

All other types of this form are optional.

Minimum-width integer types

The typedef name int_leastN_t designates a signed

integer type with a width of at least N, such that no signed integer type with lesser size has at least the

specified width. Thus, int_least32 _t denotes a signed

integer type with a width of at least 32 bits.

The typedef name uint_leastN_t designates an unsigned

integer type with a width of at least N, such that no unsigned integer type with lesser size has at least the

specified width. Thus, uint_ least16_t denotes an

unsigned integer type with a width of at least 16 bits. The following types are required:

int_least8_t

int_least16_t

int_least32_t

int_least64_t

uint_least8_t

uint_least16_t

uint_least32_t

uint_least64_t

All other types of this form are optional.

Fastest minimum-width integer types

Each of the following types designates an integer type that is usually fastest to operate with among all integer types that have at least the specified width. The designated type is not guaranteed to be fastest for all purposes; if the implementation has no clear grounds for choosing one type over another, it will simply pick some integer type satisfying the signedness and width requirements.

Headers stdint.h(3HEAD)

The typedef name int_fastN_t designates the fastest

signed integer type with a width of at least N. The

typedef name uint_fastN_ t designates the fastest

unsigned integer type with a width of at least N. The following types are required:

int_fast8_t

int_fast16_t

int_fast32_t

int_fast64_t

uint_fast8_t

uint_fast16_t

uint_fast32_t

uint_fast64_t

All other types of this form are optional. Integer types capable of holding object pointers

intptr_t Designates a signed integer type with the

property that any valid pointer to void can be converted to this type, then converted back to a pointer to void, and the result will compare equal to the original pointer.

uintptr_t Designates an unsigned integer type with

the property that any valid pointer to void

can be converted to this type, then con-

verted back to a pointer to void, and the result will compare equal to the original pointer.

On standard-conforming systems, the intptr_t and

uintptr_t types are required; otherwise, they are

optional.

Greatest-width integer types

intmax_t Designates a signed integer type capable of

representing any value of any signed integer type.

uintmax_t Designates an unsigned integer type capable

of representing any value of any unsigned integer type.

These types are required. Applications can test for optional types by using the

corresponding limit macro from Limits of Specified-Width

Integer Types.

Limits of Specified-Width Integer Types

The following macros specify the minimum and maximum limits

of the types declared in the header. Each macro

name corresponds to a similar type name in Integer Types. Each instance of any defined macro is replaced by a constant

expression suitable for use in #if preprocessing directives.

This expression has the same type as would an expression that is an object of the corresponding type converted

according to the integer promotions. Its implementation-

defined value is equal to or greater in magnitude (absolute value) than the corresponding value given below, with the same sign, except where stated to be exactly the given value.

Limits of exact-width integer types

o Minimum values of exact-width signed integer

types:

{INTN_MIN} Exactly -(2^N-1)

o Maximum values of exact-width signed integer

types:

{INTN_MAX} Exactly 2^N-1 -1

o Maximum values of exact-width unsigned integer

types:

{UINTN_MAX} Exactly 2^N -1

Limits of Other Integer Types The following macros specify the minimum and maximum limits of integer types corresponding to types defined in other standard headers. Each instance of these macros is replaced by a constant

expression suitable for use in #if preprocessing directives.

This expression has the same type as would an expression that is an object of the corresponding type converted

according to the integer promotions. Its implementation-

defined value is equal to or greater in magnitude (absolute value) than the corresponding value given below, with the same sign.

Limits of ptrdiff_t:

{PTRDIFF_MIN} -65535

{PTRDIFF_MAX} +65535

Limits of sig_atomic_t:

{SIG_ATOMIC_MIN} See below.

{SIG_ATOMIC_MAX} See below.

Limits of size_t:

{SIZE_MAX} 65535

Limits of wchar_t:

{WCHAR_MIN} See below.

Headers stdint.h(3HEAD)

{WCHAR_MAX} See below.

Limits of wint_t:

{WINT_MIN} See below.

{WINT_MAX} See below.

If sig_atomic_t (see the header) is defined as a

signed integer type, the value of {SIG_ATOMIC_MIN} is no

greater than -127 and the value of {SIG_ATOMIC_MAX} is no

less than 127. Otherwise, sig_atomic_t is defined as an

unsigned integer type, the value of {SIG_ATOMIC_MIN} is 0,

and the value of {SIG_ATOMIC_MAX} is no less than 255.

If wchar_t (see the header) is defined as a

signed integer type, the value of {WCHAR_MIN} is no greater

than -127 and the value of {WCHAR_MAX} is no less than 127.

Otherwise, wchar_t is defined as an unsigned integer type,

and the value of {WCHAR_MIN} is 0 and the value of

{WCHAR_MAX} is no less than 255.

If wint_t (see the header) is defined as a signed

integer type, the value of {WINT_MIN} is no greater than

-32767 and the value of {WINT_MAX} is no less than 32767.

Otherwise, wint_t is defined as an unsigned integer type,

and the value of {WINT_MIN} is 0 and the value of {WINT_MAX}

is no less than 65535. Macros for Integer Constant Expressions The following macros expand to integer constant expressions suitable for initializing objects that have integer types

corresponding to types defined in the header.

Each macro name corresponds to a similar type name listed

under minimum-width integer types and greatest-width integer

types. Each invocation of one of these macros expands to an integer

constant expression suitable for use in #if preprocessing

directives. The type of the expression has the same type as would an expression that is an object of the corresponding type converted according to the integer promotions. The

value of the expression is that of the argument. The argu-

ment in any instance of these macros is a decimal, octal, or

hexadecimal constant with a value that does not exceed the limits for the corresponding type.

Macros for minimum-width integer constant expressions

The macro INTN_C(value) expands to an integer constant

expression corresponding to the type int_leastN_t. The

macro UINTN_C(value) expands to an integer constant

expression corresponding to the type uint_leastN_t. For

example, if uint_least64_t is a name for the type

unsigned long long, then UINT64_C(0x123) might expand to

the integer constant 0x123ULL.

Macros for greatest-width integer constant expressions

The following macro expands to an integer constant expression having the value specified by its argument

and the type intmax_t:

INTMAX_C(value)

The following macro expands to an integer constant expression having the value specified by its argument

and the type uintmax_t:

UINTMAX_C(value)
