std::alloca...ts::max_size(3) C++ Standard Libary std::alloca...ts::max_size(3) NAME std::allocator_traits::max_size - std::allocator_traits::max_size Synopsis Defined in header <memory> static size_type max_size( const Alloc& a ) noexcept; (since C++11) (until C++20) static constexpr size_type max_size( const Alloc& a ) noexcept; (since C++20) If possible, obtains the maximum theoretically possible allocation size from the allocator a, by calling a.max_size(). If the above is not possible (e.g. Alloc does not have the member func- tion max_size()), then returns std::numeric_limits<size_type>::max() / sizeof(value_type). Parameters a - allocator to detect Return value Theoretical maximum allocation size. Defect reports The following behavior-changing defect reports were applied retroac- tively to previously published C++ standards. DR Applied to Behavior as published Cor- rect behavior LWG 2162 C++11 max_size was not requied to be noexcept re- quired LWG 2466 C++11 theoretical maximum allocation size in bytes size in elements is was returned as fallback re- turned See also max_size returns the largest supported allocation size (until C++20) (public member function of std::allocator<T>) http://cppreference.com 2024.06.10 std::alloca...ts::max_size(3)
