NAME

       avr_stdint - <stdint.h>: Standard Integer Types

SYNOPSIS

   Exact-width integer types
       Integer types having exactly the specified width
       typedef signed char int8_t
       typedef unsigned char uint8_t
       typedef signed int int16_t
       typedef unsigned int uint16_t
       typedef signed long int int32_t
       typedef unsigned long int uint32_t
       typedef signed long long int int64_t
       typedef unsigned long long int uint64_t

   Integer types capable of holding object pointers
       These allow you to declare variables of the same size as a pointer.
       typedef int16_t intptr_t
       typedef uint16_t uintptr_t

   Minimum-width integer types
       Integer types having at least the specified width
       typedef int8_t int_least8_t
       typedef uint8_t uint_least8_t
       typedef int16_t int_least16_t
       typedef uint16_t uint_least16_t
       typedef int32_t int_least32_t
       typedef uint32_t uint_least32_t
       typedef int64_t int_least64_t
       typedef uint64_t uint_least64_t

   Fastest minimum-width integer types
       Integer types being usually fastest having at least the specified width
       typedef int8_t int_fast8_t
       typedef uint8_t uint_fast8_t
       typedef int16_t int_fast16_t
       typedef uint16_t uint_fast16_t
       typedef int32_t int_fast32_t
       typedef uint32_t uint_fast32_t
       typedef int64_t int_fast64_t
       typedef uint64_t uint_fast64_t

   Greatest-width integer types
       Types designating integer data capable of representing any value of any integer type in
       the corresponding signed or unsigned category
       typedef int64_t intmax_t
       typedef uint64_t uintmax_t

   Limits of specified-width integer types
       C++ implementations should define these macros only when __STDC_LIMIT_MACROS is defined

   Limits of other integer types

       #define WINT_MIN   __WINT_MIN__

   Macros for integer constants
       C++ implementations should define these macros only when __STDC_CONSTANT_MACROS is defined
       before <stdint.h> is included.

       These definitions are valid for integer constants without suffix and for macros defined as
       integer constant without suffix
       #define INT8_C(value)   ((int8_t) value)
       #define UINT8_C(value)   ((uint8_t) __CONCAT(value, U))
       #define INT16_C(value)   value
       #define UINT16_C(value)   __CONCAT(value, U)

       #define INT64_C(value)   __CONCAT(value, LL)
       #define UINT64_C(value)   __CONCAT(value, ULL)
       #define INTMAX_C(value)   __CONCAT(value, LL)
       #define UINTMAX_C(value)   __CONCAT(value, ULL)

Detailed Description

       #include <stdint.h>

       Use [u]intN_t if you need exactly N bits.

       Since these typedefs are mandated by the C99 standard, they are preferred over rolling
       your own typedefs.
