class CMessage
{
public:int a;
       CMessage(){}
       ~CMessage(){}
};
void Testing(CMessage *f_pMessage)//l_pMessage is output parameter
{
    f_pMessage = new CMessage();
    f_pMessage->a = 1;
}
int main()
{
    CMessage *l_pMessage =NULL;
    Testing(l_pMessage);
    std::cout<<l_pMessage->a;//getting l_pMessage = NULL;
    return 0;
}
