在删除之前测试C ++中的void指针 [英] Test for void pointer in C++ before deleting

问题描述

我在C ++中有一个数组：

  Player ** playerArray; 
  

这是在它的类的构造函数中初始化的。

在析构函数中，我有：

  delete playerArray;除了通过Valgrind测试程序时，它表示有一些调用要删除一个void指针：
 



<

 操作员delete（void *）
  

我想在调用delete之前测试playerArray是否为void指针，以避免此错误。

有人知道如何做？ $

解决方案

也许你的意思是 delete [] playerArray 。如果指针是数组，而不是单个实例，则需要 [] 。

I have an array in C++:

Player ** playerArray;

which is initialized in the constructor of the class it is in.

In the destructor I have:

delete playerArray;

except when testing the program through Valgrind it says that there are some calls to delete to a void pointer:

 operator delete(void*)

I want to test whether the playerArray is a void pointer before calling delete to avoid this error.

Does anyone know how to do this?

解决方案

Perhaps you meant delete [] playerArray. You need the [] if the pointer is an array, not a single instance.
