std::__new_allocator< _Tp >(3)                        Library Functions Manual

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 >.

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.

       o all allocation calls operator new

       o 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.
