to happyparrot:

代码如下：

REQUEST * getRequestStructMFC(char * inputStr)
{
REQUEST * req = (REQUEST*)malloc(sizeof(REQUEST));
CString tempStr;
CString ss;
char* str = NULL;
char * retStr = NULL;
for(int i = 0; i < 9; i++)
{
AfxExtractSubString(tempStr,inputStr,i,'\n');
str = (char*)malloc(tempStr.GetLength() + 1);
strcpy(str,tempStr);
AfxExtractSubString(ss,str,1,'=');
free(str);
str = NULL;
retStr = (char*)malloc(ss.GetLength() + 1);
strcpy(retStr,ss);
if (i == 0)
{
(*req).mallid = retStr;
}
if (i == 1)
{
(*req).termno = retStr;
}
if (i == 2)
{
(*req).order = retStr;
}
if (i == 3)
{
(*req).gcode= retStr;
}
if (i == 4)
{
(*req).paydate = retStr;
}
if (i == 5)
{
(*req).name = retStr;
}
if (i == 6)
{
(*req).cardno = retStr;
}
if (i == 7)
{
(*req).limit = retStr;
}
if (i == 8)
{
(*req).price = retStr;
}
}
return req;






typedef struct a
{
char * mallid;
char * termno;
char * order;
char * gcode;
char * paydate;
char * name;
char * cardno;
char * limit;
char * price;
} REQUEST;
}

并且，为何是释放free((*reqStruct).cardno);而不是free(*reqStruct)呢？或者free(reqStruct)

reqStruct = getRequestStructMFC(cReqStr);
这个函数的帮助信息中说了返回信息需要由外部进行free么？

代码有些长，出错位置在最后：free((*reqStruct).cardno); //<------------- exception
malloc之后为什么要free()? free到底释放了什么？
通俗的来说，malloc是分配内存 free是释放malloc所分配的内存。...那么free()所释放的内存到底是什么呢？ 我们应该知道，在我们malloc这块区域之前，这块内存就有它自己的内容 当我们free()掉了这块内存，
free出错
free函数
free()出错
malloc后free出错总结： 1、malloc与free配套使用。不要跨进程分配和释放； 2、指向malloc申请的堆内存的指针，在运用过程中千万不要另外赋值，否则同样导致内存泄露（我曾经犯过这样的错误） 3、malloc后，实际...
new的数据能用free吗？
我的标题是我今天看到的一个面试题，...凭自己的直觉吧，猜了个“不可以”的答案，虽然对了，但我不知道为什么。于是 我就查查资料了： 不可以，new对应delete不可以张冠李戴。 malloc/free,new/delete必需
关于free()函数经常出错的细节问题
在标准C语言中，malloc() 和 free()是一对操作，有malloc()之后要有free()释放内存。另外在C++中也有一对类似的操作new 和delete，这两对完成的功能类似，但是这两对稍稍有些不同，这些就不讨论它们的区别，只讨论...
