结构数组的智能指针？ [英] Smart pointer for arrays of structs?

问题描述

我有一些数据存储为普通的旧C结构。到目前为止，我已经在堆栈上有这些结构的数组，但由于堆栈溢出，我需要将这些结构移动到堆中。

我一直在尝试一些智能指针来帮助，但到目前为止，我一直在处理的

实现与[]运算符

有问题，因为它可以使用带有unsigned char的相同类时会发生冲突。


您对能够使用数组的智能指针有什么建议吗？


我需要类似的东西：


ptr =（new或malloc）MY_STRUCT [16];


ptr [i] .member


谢谢。

std :: vector有什么问题？

std :: vector有什么问题？

我忘了提到要求从外部C函数访问数据需要
。因此，它需要像普通数组一样序列化。

std :: vector符合这个要求。

vector存储它的内存连续的

Hi,

I have some data which is stored as plain old C structures. Until now I''ve
had arrays of these structs on stack but due to stack overrun I need to move
these to heap.
I''ve been trying out some smart pointers to help but so far the
implementation I''ve been dealing with has had problems with [] operator
since it could conflict when using the same class with "unsigned char".

Do you have any recommendations for smart pointers able to work with arrays?

I would need something like:

ptr = (new or malloc) MY_STRUCT [16];

ptr[i].member

Thanks.

What is wrong with std::vector ?

I forgot to mention that it''s a requirement that the data needs to be
accessible from external C functions. For this reason it needs to be
serialized just like an ordinary array.

std::vector fits the bill for that.

vector stores it''s memory contiguous
