std::scoped_allocator_adaptor
Defined in header <scoped_allocator>
pointer allocate( size_type n );
 (1) (since C++11)
pointer allocate( size_type n, const_void_pointer hint );
 (2) (since C++11)

Uses the outer allocator to allocate uninitialized storage.

1) Calls std::allocator_traits <OuterAlloc> :: allocate (outer_allocator( ), n)
2) Additionally provides memory locality hint, by calling std::allocator_traits <OuterAlloc> :: allocate (outer_allocator( ), n, hint)

Parameters

n - the number of objects to allocate storage for
hint - pointer to a nearby memory location

Return value

The pointer to the allocated storage.
