NAME
       std::__new_allocator< _Tp > - An allocator that uses global new, as per
       C++03 [20.4.1].

SYNOPSIS
       #include <memory>

       Inherited by std::allocator< value_type >, __gnu_cxx::new_allocator< _Tp
       >, and std::allocator< _Tp >.

       typedef std::size_t size_type
       typedef _Tp value_type

Detailed Description
   template<typename _Tp>
       class std::__new_allocator< _Tp >"An allocator that uses global new, as
       per C++03 [20.4.1].

       This is precisely the allocator defined in the C++ Standard.

       • all allocation calls operator new

       • all deallocation calls operator delete

       This  is the default base-class implementation of std::allocator, and is
       also the  base-class  of  the  __gnu_cxx::new_allocator  extension.  You
       should  use either std::allocator or __gnu_cxx::new_allocator instead of
       using this directly.

       Template Parameters
           _Tp Type of allocated object.
