__gnu_cxx::_Relative_pointer_impl< _Tp > - SYNOPSIS
Public Types typedef _Tp element_type Public Member Functions _Tp * get () const bool operator< (const _Relative_pointer_impl &__rarg) const bool operator== (const _Relative_pointer_impl &__rarg) const void set (_Tp *__arg) 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.

This allocator specifies that containers use a 'relative pointer' as it's pointer type. (See ext/pointer.h) Memory allocation in this example is still performed using std::allocator.
