IMoniker::IsSystemMoniker

Indicates whether this moniker is one of the system-supplied moniker classes.

HRESULT IsSystemMoniker(

DWORD *pdwMksys	//Receives value from MKSYS enumeration
);

Parameter
pdwMksys

[out] Receives an integer that is one of the values from the MKSYS enumeration. This parameter cannot be NULL. For information on the MKSYS enumeration, see the "Data Structures" section.

Return Values
S_OK

The moniker is a system moniker.

S_FALSE

The moniker is not a system moniker.

Comments
Notes to Callers
New values of the MKSYS enumeration may be defined in the future; therefore you should explicitly test for each value you are interested in.

Notes to Implementors
Your implementation of this method must return MKSYS_NONE. You cannot use this function to identify your own monikers (for example, in your implementation if IMoniker::ComposeWith). Instead, you should use your moniker's implementation of IPersist::GetClassID or use IUnknown::QueryInterface to test for your own private interface.
