Detailed Description

template<typename _Tp>

class __gnu_cxx::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

Template Parameters

_Tp Type of allocated object.
