Detailed Description

template<typename _Tp>
class __gnu_cxx::_ExtPtr_allocator< _Tp >

An example allocator which uses a non-standard pointer type.

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.
