HRESULT IsSystemMoniker(
| 
 DWORD *pdwMksys  | 
 //Pointer to value from MKSYS enumeration  | 
| 
 );  | 
Parameter
Return Values
Remarks
New values of the MKSYS enumeration may be defined in the future; therefore you should explicitly test for each value you are interested in.
Your implementation of this method must return MKSYS_NONE. You cannot use this function to identify your own monikers (for example, in your implementation of IMoniker::ComposeWith). Instead, you should use your moniker’s implementation of IPersist::GetClassID or use IUnknown::QueryInterface to test for your own private interface.
