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.
