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

This is a non-standard extension that can be used to guarantee allocation from new even if the library has been configured to use a different implementation for std::allocator.

Template Parameters

_Tp	Type of allocated object.
