Detailed Description
template<typename _Tp> class __gnu_cxx::_Relative_pointer_impl< _Tp >
A storage policy for use with _Pointer_adapter<> which stores the
pointer's address as an offset value which is relative to its own
address.
This is intended for pointers within shared memory regions which might
be mapped at different addresses by different processes. For null
pointers, a value of 1 is used. (0 is legitimate sometimes for nodes in
circularly linked lists) This value was chosen as the least likely to
generate an incorrect null, As there is no reason why any normal
pointer would point 1 byte into its own pointer address.
