__gnu_cxx::_Relative_pointer_impl< _Tp >(3cxx)                    __gnu_cxx::_Relative_pointer_impl< _Tp >(3cxx)

NAME

       __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.

SYNOPSIS

       #include <pointer.h>

   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.
