如何访问SAFEARRAY中的数据?

[fancy_zhh]

void (SAFEARRAY ** safearray)
{
//如何在这里读写safearray中的数据
//????????????????????????????
}

int main {
unsigned int cn = 10;
SAFEARRAY * p = SafeArrayCreateVector(VT_UI4,0,&cn);
void * pData;
SafeArrayAccessData(p,&pData);
strcpy(pData,"0123456789");

//调用上面的这个函数,在函数内部读取
f(&p); //???????????????????????????????????

SafeArrayUnaccessData(p);
SafeArrayDestroy(p);
}

void f(SAFEARRAY **safearray)
{
PChar S = (PChar)safearray[0]->pvData;
ShowMessage(S);
}

void __fastcall TForm1::Button1Click(TObject *Sender)
{
unsigned long cn = 10;
SAFEARRAY * p = SafeArrayCreateVector(VT_UI4, 0, cn);
void *pData;
SafeArrayAccessData(p, &pData);
Move("0123456789", pData, 10);

//调用上面的这个函数,在函数内部读取
f(&p); //???????????????????????????????????

SafeArrayUnaccessData(p);
SafeArrayDestroy(p);
}

这样可行，但我在ActiveX传递时却根据不对
