NAME

       <stdint.h>: Standard Integer Types -

   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 uint8_t uint_least8_t
       typedef int16_t int_least16_t
       typedef uint16_t uint_least16_t

       typedef uint32_t uint_least32_t
       typedef int64_t int_least64_t

       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

   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 UINT32_C(value)   __CONCAT(value, UL)
       #define INT64_C(value)   __CONCAT(value, LL)

       #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.
