Supplies typedefs for standard integer types such as int32_t or uint_least16_t. + Use in preference to <stdint.h> + for enhanced portability. Furthermore, all names are safely placed in the boost namespace.

Rationale

+

The organization of boost integer headers and classes is designed to take +advantage of <stdint.h> types from the 1999 C standard +without resorting to 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. As always, 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. + +

Caveat emptor

+

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. + +
