指向指针的指针的内存析放问题？

[guoxiny]

GetMemory(char** p)
{
*p = malloc(10);
}

char** p;
p = (char**)new char;
GetMemory(p);
free(*p);
delete p;//error这里会出现错误
请问这样分配的内存如何析放呢？

[chinajiji]

GetMemory(char** p)
{
*p = (char*)malloc(10);
}

char** p;
//p = (char**)new char;
GetMemory(p);
free(*p);
//delete p;//

[jinyongzhi]

p = (char**)new char;//此处错误，应为p = new char*；在你的程序里，其实完全不需要这步，直接p=NULL；
delete p;//如果上面new了，此处就应该delete，否则内存就泄漏了
GetMemory(p);

sorry，我说的有问题，再看看：（

[chinajiji]

GetMemory(char** p)
{
*p = new char[10];
}

char** p;
p = new char*;
GetMemory(p);
delete *p;
delete p;

[chinajiji]

delete *p;
改为:
delete []*p;

[Cybergate]

p = (char**)new char;
改为
p = new char*

[jinyongzhi]

把*p = malloc(10);改为 *p = (char*)malloc(10);
p = (char**)new char;改为 p = new char*;
就OK了，

你这样不对吧p = (char**)new char;，把一个本来是char*地址强行转化为char**,
后面又试图delete p? 本来就不能这样来。如果你非要如此。就没有必要delete p，free(*p)就已经释放完了。后面写上p=null就可以了

chinajiji is right!!
