定义于头文件 <memory>
static void deallocate( Alloc& a, pointer p, size_type n );		(始于 C++11) (constexpr 始于 C++20)

使用分配器 a 以解分配由 p 引用的存储，通过调用 a.deallocate(p, n)。

参数

a	-	要使用的分配器
p	-	指向先前分配的存储的指针
n	-	存储分配用于的对象数量

返回值

(无)

参见

allocate [静态]	使用分配器分配未初始化的存储 (public static member function)
deallocate	解分配存储 (public member function of std::allocator<T>)
