因為沒有任何 COM 相當於std::unique_ptr,單一擁有者和多個擁有者的情況下使用這些智慧型指標。兩者都CComPtr和ComQIPtr支援移動有右值參考的作業。範例下列範例示範如何使用CComPtr,COM 物件具現化,並取得其介面指標。請注意, CComPtr::CoCreateInstance成員函式用來建立 COM 物件,而非 Win32 函式具有相同的名稱。

This lets us read thechar *strpointer. If we could control the value ofstr, we could use this to arbitrary read. 3.2. "Delete result" case2:puts("Result deleted"); result.reset();return; It callsstd::unique_ptr<Request>::reset, which destructs theRequestand frees it. So we can tot...
Another possible solution to many of the above problems is to dynamically allocate the “optional” value and pass it via pointer – ideallystd::unique_ptr. Given that we C++ programmers are accustomed to using pointers, this solution has good usability: a null pointer indicates the no-value ...
