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.
- 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.
