constexpr void std::allocator_traits< allocator< void > >::construct	(	allocator_type &	,
		_Up *	__p,
		_Args &&...	__args )

inlinestaticconstexprnoexcept

Construct an object of type _Up.

Parameters

__a	An allocator.
__p	Pointer to memory of suitable size and alignment for an object of type _Up.
__args	Constructor arguments.

Calls __a.construct(__p, std::forward<_Args>(__args)...) in C++11, C++14 and C++17. Changed in C++20 to call std::construct_at(__p, std::forward<_Args>(__args)...) instead.
