IMoniker::IsSystemMoniker method (objidl.h)

  • Article

Determines whether this moniker is one of the system-provided moniker classes.

Syntax

HRESULT IsSystemMoniker(
  [out] DWORD *pdwMksys
);

Parameters

[out] pdwMksys

A pointer to a variables that receives one of the values from the MKSYS enumeration and refers to one of the COM moniker classes. This parameter cannot be NULL.

Return value

This method returns S_OK to indicate that the moniker is a system moniker, and S_FALSE otherwise.

Remarks

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 IPersist::GetClassID or use QueryInterface to test for your own private interface.
