如何封装delete[] p; p = null;

[CG_XinBing]

一般new动态分配内存之后，都要删除之，代码都一样;
delete[] p; p = null;
但总是这样写很麻烦，最好可以把这二句封装在一个函数中。但指针指向结构体千差万别，如何做啊？谢谢！

LZ没听过析构函数么

[hai040]

boost::smart_ptr?

我觉得不要封装的好，如果是一个局部的指针就麻烦了。

[「已注销」]

定义一个宏岂不更简单？

#define DelArray(x) delete [] x; x = NULL

[ahao]

template<typename T>
void safeDelete(T *& p_t)
{
    delete p_t;
    p_t = NULL;
}

那我觉得你还不如去用JAVA了

[机智的呆呆]

#define ARRAYDELETE(p) {delete[] (p); (p) = null;}

[linyongzuo]

void dele( int **p )
{
	delete[] *p;
	*p = NULL;
}
int main()
{
	int *p = new int[3];
	p[0]=1;
	p[1]=2;
	p[2]=3;
	// ...
	dele( &p );//封装
}

[gzliaojian]

#define SAFE_DELETE(p) { if(p) { delete p; p=NULL; } }
#define SAFE_DELETE_ARRAY(p) { if(p) { delete[] p; p=NULL; } }

C/C++ code

#define ARRAYDELETE(p) {delete[] (p); (p) = null;}

俺就这么做的。还有有些要调用Release的com接口
