designers are not even in a good mood. All of this is to satisfy the so-called principle of "who applies and who releases. The best way to solve this problem is to dynamically apply for memory in the function based on actual needs, and the caller is responsible for releasing the memory. Although this violates the above principles, COM is designed in this way based on convenience and efficiency.　 　 C Language C ++ Language Win
