        The header <boost/core/typeinfo.hpp>
        defines a class boost::core::typeinfo, which is an alias for std::type_info
        when RTTI is enabled, and is a reasonable substitute when RTTI is not supported.
      
        The macro BOOST_CORE_TYPEID,
        when applied to a type T,
        is the equivalent of typeid(T)
        and produces a reference to a const typeinfo
        object.
      
        The function boost::core::demangled_name takes a boost::core::typeinfo const & ti and either returns ti.name(),
        when that string doesn't need to be demangled, or boost::core::demangle(ti.name()),
        when it does. The return type of boost::core::demangled_name
        is char const* in the first case and std::string
        in the second.
      
namespace boost { namespace core { class typeinfo; /* char const* or std::string */ demangled_name( typeinfo const & ti ); } } #define BOOST_CORE_TYPEID(T) /*unspecified*/
#include <boost/core/typeinfo.hpp> #include <iostream> template<class T1, class T2> struct X { }; int main() { typedef X<void const*, void(*)(float)> T; boost::core::typeinfo const & ti = BOOST_CORE_TYPEID(T); std::cout << boost::core::demangled_name( ti ) << std::endl; }
