NAME¶
std::scoped_allocator_adaptor::allocate - std::scoped_allocator_adaptor::allocate
Synopsis¶
Defined in header <scoped_allocator>
pointer allocate( size_type n ); (since C++11)
(until C++20)
[[nodiscard]] pointer allocate( size_type n ); (since C++20)
pointer allocate( size_type n, (1) (since C++11)
const_void_pointer hint ); (2) (until C++20)
[[nodiscard]] pointer allocate( size_type n, (since C++20)
const_void_pointer hint );
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.
