std::allocator::construct(3) C++ Standard Libary std::allocator::construct(3) NAME std::allocator::construct - std::allocator::construct Synopsis Defined in header <memory> void construct( pointer p, const_reference val ); (1) (until C++11) template< class U, class... Args > (since C++11) void construct( U* p, Args&&... args ); (2) (deprecated in C++17) (removed in C++20) Constructs an object of type T in allocated uninitialized storage pointed to by p, using global placement-new. 1) Calls ::new((void*)p) T(val). 2) Calls ::new((void*)p) U(std::forward<Args>(args)...). Parameters p - pointer to allocated uninitialized storage val - the value to use as the copy constructor argument args... - the constructor arguments to use Return value (none) Defect reports The following behavior-changing defect reports were applied retroac- tively to previously published C++ standards. DR Applied to Behavior as published Correct behavior LWG 402 C++98 if T::operator new exists, the uses global re- placement-new program might be ill-formed instead See also construct constructs an object in the allocated storage [static] (function template) construct_at creates an object at a given address (C++20) (function template) operator new allocation functions operator new[] (function) http://cppreference.com 2024.06.10 std::allocator::construct(3)
