Remarks
CComObjectStack is used to create a temporary COM object and provide the object a skeletal implementation of IUnknown. Typically, the object is used as a local variable within one function (that is, pushed onto the stack). Since the object is destroyed when the function finishes, reference counting is not performed to increase efficiency.
The following example shows how to create a COM object used inside a function:
void MyFunc()
{
CComObjectStack<CMyClass2> Tempobj;
//...
}
The temporary object Tempobj is pushed onto the stack and automatically disappears when the function finishes.
