std::pmr::memory_resource
void deallocate ( void * p,

std:: size_t bytes,

std:: size_t alignment = alignof ( std:: max_align_t ) ) ;
(C++17 起)

释放由 p 指向的存储空间。 p 必须是通过先前调用与 * this 相等的 memory_resource 上的 allocate ( bytes, alignment ) 所返回的指针，且其指向的存储空间尚未被释放。

等效于 do_deallocate ( p, bytes, alignment ) ; 。

异常

不抛出任何异常。
