Args > constexpr T* uninitialized_construct_using_allocator( T* p, const (since C++20) Alloc& alloc, Args&&... args ); Creates an object of the given type T by means of uses-allocator construction at the uninitialized memory location indicated by p Equivalent to return std::apply([&]<class... Xs>(Xs&&...xs) { return std::construct_at(p, std::forward<Xs>(xs)...); }, std::uses_allocator_construction_args<T>(alloc, std::for- ward<Args>(args)...)); Parameters p - the memory location where the object will be placed. alloc - the allocator to use. args - the arguments to pass to T's constructor Return value Pointer to the newly-created object of type T Exceptions May throw any exception thrown by the constructor of T, typically including std::bad_alloc Example This section is incomplete Reason: no example See also uses_allocator checks if the specified type supports uses- allocator (C++11) construction (class template) make_obj_using_allocator creates an object of the given type by means of (C++20) uses-allocator construction (function template) http://cppreference.com 2022.07.31 std::uninit...g_allocator(3)
