size_type max_size() const throw();		(C++11 前)
size_type max_size() const noexcept;		(C++11 起) (C++17 中已棄用) (C++20 中移除)

返回 n 的最大理論可能值，對於此值，呼叫 allocate(n, 0) 可能會成功。

在大多數實現中，這返回 std::numeric_limits<size_type>::max() / sizeof(value_type)。

引數

(無)

返回值

支援的最大分配大小。

max_size [靜態]

返回分配器支援的最大物件大小 (std::allocator_traits<Alloc> 的公共靜態成員函式)
