std::scoped_allocator_adaptor<OuterAlloc,InnerAlloc...>::allocate
Since C++20
// 1)
[[nodiscard]] pointer allocate( size_type n );
// 2)
[[nodiscard]] pointer allocate( size_type n, const_void_pointer hint );
Since C++11, Until C++20
// 1)
pointer allocate( size_type n );
// 2)
pointer allocate( size_type n, const_void_pointer hint );
Uses the outer allocator to allocate uninitialized storage.
- Calls
std::allocator_traits<OuterAlloc>::allocate(outer_allocator(), n)
- 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
