+

+ The header <boost/cstdint.hpp> + provides the typedef's useful for writing portable code that requires certain + integer widths. All typedef's are in namespace boost. +

+

+ The specifications for these types are based on the ISO/IEC 9899:1999 C Language + standard header <stdint.h>. The 64-bit types required by the C standard + are not required in the boost header, and may not be + supplied for all platforms/compilers, because long long + is not [yet] included in the C++ standard. +

+

+ See cstdint_test.cpp for + a test program. +

+
+
+
+

+ The organization of the Boost.Integer headers and classes is designed to + take advantage of <stdint.h> types from the 1999 C standard without + causing undefined behavior in terms of the 1998 C++ standard. The header + <boost/cstdint.hpp> makes the standard integer types safely available + in namespace boost without placing any names in namespace + std. The intension is to complement rather than compete + with the C++ Standard Library. Should some future C++ standard include <stdint.h> + and <cstdint>, then <boost/cstdint.hpp> will continue to function, + but will become redundant and may be safely deprecated. +

+

+ Because these are boost headers, their names conform to boost header naming + conventions rather than C++ Standard Library header naming conventions. +

+
+
+
+

+ As an implementation artifact, certain C <limits.h> macro names may + possibly be visible to users of <boost/cstdint.hpp>. Don't use these + macros; they are not part of any Boost-specified interface. Use boost::integer_traits<> + or std::numeric_limits<> instead. +

+

+ As another implementation artifact, certain C <stdint.h> typedef names + may possibly be visible in the global namespace to users of <boost/cstdint.hpp>. + Don't use these names, they are not part of any Boost-specified interface. + Use the respective names in namespace boost instead. +

+
+
+
+

+ The typedef int#_t, with # replaced by the width, designates + a signed integer type of exactly # bits; for example int8_t + denotes an 8-bit signed integer type. Similarly, the typedef uint#_t + designates an unsigned integer type of exactly # bits. +

+

+ These types are optional. However, if a platform supports integer types with + widths of 8, 16, 32, 64, or any combination thereof, then <boost/cstdint.hpp> + does provide the corresponding typedefs. +

+

+ The absence of int64_t and uint64_t is indicated by the macro BOOST_NO_INT64_T. +

+
+
+
+

+ The typedef int_least#_t, with # replaced by the width, + designates a signed integer type with a width of at least # bits, such that + no signed integer type with lesser size has at least the specified width. + Thus, int_least32_t denotes the smallest signed integer + type with a width of at least 32 bits. Similarly, the typedef name uint_least#_t + designates an unsigned integer type with a width of at least # bits, such + that no unsigned integer type with lesser size has at least the specified + width. +

+

+ The following minimum-width integer types are provided for all platforms: +

+
    +
  • + int_least8_t +
    • +
  • + int_least16_t +
    • +
  • + int_least32_t +
    • +
  • + uint_least8_t +
    • +
  • + uint_least16_t +
    • +
  • + uint_least32_t +
    • +
+

+ The following types are available only if, after including <boost/cstdint.hpp>, + the macro BOOST_NO_INT64_T is not defined: +

+
    +
  • + int_least64_t +
    • +
  • + uint_least64_t +
    • +
+

+ All other minimum-width integer types are optional. +

+
+
+
+

+ The typedef int_fast#_t, with # replaced by the width, + designates the fastest signed integer type with a width of at least # bits. + Similarly, the typedef name uint_fast#_t designates the + fastest unsigned integer type with a width of at least # bits. +

+

+ There is no guarantee that these types are fastest for all purposes. In any + case, however, they satisfy the signedness and width requirements. +

+

+ The following fastest minimum-width integer types are provided for all platforms: +

+
    +
  • + int_fast8_t +
    • +
  • + int_fast16_t +
    • +
  • + int_fast32_t +
    • +
  • + uint_fast8_t +
    • +
  • + uint_fast16_t +
    • +
  • + uint_fast32_t +
    • +
+

+ The following types are available only if, after including <boost/cstdint.hpp>, + the macro BOOST_NO_INT64_T is not defined: +

+
    +
  • + int_fast64_t +
    • +
  • + uint_fast64_t +
    • +
+

+ All other fastest minimum-width integer types are optional. +

+
+
+
+

+ The typedef intmax_t designates a signed integer type + capable of representing any value of any signed integer type. +

+

+ The typedef uintmax_t designates an unsigned integer type + capable of representing any value of any unsigned integer type. +

+

+ These types are provided for all platforms. +

+
+
+
+

+ The following macros are always defined after inclusion of this header, these + allow integer constants of at least the specified width to be declared: INT8_C, + UINT8_C, INT16_C, UINT16_C, INT32_C, UINT32_C, INTMAX_C, UINTMAX_C. +

+

+ The macros INT64_C and UINT64_C are also defined if the the macro BOOST_NO_INT64_T + is not defined. +

+

+ The C99 macro __STDC_CONSTANT_MACROS is also defined as an artifact of the + implementation. +

+

+ For example: +

+
#include <boost/cstdint.hpp>
+
+// Here the constant 0x1FFFFFFFF has the correct suffix applied:
+static const boost::uint64_t c = INT64_C(0x1FFFFFFFF);
