是否有其返回的结构直接是很好的做法无论如何？ [英] Is there any case for which returning a structure directly is good practice?

问题描述

IMO所有code直接返回结构可以被修改以返回指针结构

IMO all code that returns structure directly can be modified to return pointer to structure.

当直接返回一个结构好的做法呢？

When is returning a structure directly a good practice?

推荐答案

修改的怎么样？返回指针的结构的静态实例的功能内，从而使功能非折返;或者通过指针返回给调用者必须确保自由，这样做appropiately堆中分配的结构？我会考虑返回的结构是在一般情况下，很好的做法。

Modified how? Returning a pointer to a static instance of the structure within the function, thus making the function non-reentrant; or by returning a pointer to a heap allocated structure that the caller has to make sure to free and do so appropiately? I would consider returning a structure being the good practice in the general case.
