This method checks whether moniker is one of the system-supplied types.
Syntax
HRESULT IsSystemMoniker(
DWORD* pdwMksys
);
Parameters
pdwMksys
[out] Pointer to an integer that is one of the values from the MKSYS enumeration, and refers to one of the COM moniker classes.This parameter cannot be NULL.
Return Value
The following table shows the return values for this method.
| Value | Description |
|---|---|
S_OK |
The moniker is a system moniker. |
S_FALSE |
The moniker is not a system moniker. |
Remarks
To determine whether the platform supports this interface, see Determining Supported COM APIs.
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 Implementers
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 the IPersist::GetClassID method or use the IUnknown::QueryInterface method to test for your own private interface.
Requirements
