Detailed Description

CPMUnknown is provided as a simple way for your interface to implement QueryInterface,

AddRef, and Release, which are required for all interfaces (they are pure virtual 

functions declared in IPMUnknown). In addition, it also declares and defines a helper 

function, PreDirty, which is used for persistent interfaces only.



This class provides the same functionality as the macros in HelperInterface.h; it is

intended to be a replacement for those macros. You should not need to call methods in

CPMUnknown yourself directly.



See below for an example of how to use CPMUnknown:

#include "CPMUnknown.h"

class Foo : public CPMUnknown<IFoo> {



                Foo(IPMUnknown* boss);

virtual void    SomeMethod();

private: MyStruct* fMyStruct; };

Foo:Foo(IPMUnknown* boss)

    :  CPMUnknown<IFoo>(boss),

       fMyStruct(nil)

{
