is_a()

template<typename T , typename U >

bool is_a ( U * p )

inline

Note that we deliberately do not define the 'test' member template.  Not
doing so will result in a build-time error for type relationships that have
not been defined, rather than a run-time error.  See the discussion above
for when to define this member.   

The public interface.   

A generic test for a type relationship.  See the discussion above for when
to use this function.  The question answered is "Is type T a derived type of
type U?".
