17.4.1 Header synopsis [cstdint.syn]

namespace std { using int8_t = signed integer type;
using int16_t = signed integer type;
using int32_t = signed integer type;
using int64_t = signed integer type;

using int_fast8_t = signed integer type; using int_fast16_t = signed integer type; using int_fast32_t = signed integer type; using int_fast64_t = signed integer type;

using int_least8_t = signed integer type; using int_least16_t = signed integer type; using int_least32_t = signed integer type; using int_least64_t = signed integer type;

using intmax_t = signed integer type; using intptr_t = signed integer type;

using uint8_t = unsigned integer type; using uint16_t = unsigned integer type; using uint32_t = unsigned integer type; using uint64_t = unsigned integer type;

using uint_fast8_t = unsigned integer type; using uint_fast16_t = unsigned integer type; using uint_fast32_t = unsigned integer type; using uint_fast64_t = unsigned integer type;

using uint_least8_t = unsigned integer type; using uint_least16_t = unsigned integer type; using uint_least32_t = unsigned integer type; using uint_least64_t = unsigned integer type;

using uintmax_t = unsigned integer type; using uintptr_t = unsigned integer type; }

The header also defines numerous macros of the form:

INT_[FAST LEAST]{8 16 32 64}MIN [U]INT[FAST LEAST]{8 16 32 64}_MAX INT{MAX PTR}_MIN [U]INT{MAX PTR}_MAX {PTRDIFF SIG_ATOMIC WCHAR WINT}{_MAX _MIN} SIZE_MAX

plus function macros of the form:

[U]INT{8 16 32 64 MAX}_C

The header defines all types and macros the same as the C standard library header <stdint.h>.
