COM_INTERFACE_ENTRY_AUTOAGGREGATE( iid, punk, clsid )
Parameters
iid
[in] The GUID of the interface queried for.
punk
[in] The name of an IUnknown pointer. Must be a member of the class containing the COM map.
clsid
[in] The identifier of the aggregate that will be created if punk is NULL.
Remarks
Same as COM_INTERFACE_ENTRY_AGGREGATE, except if punk is NULL, it automatically creates the aggregate described by the clsid.
For example, from the ATL sample COMMAP:
BEGIN_COM_MAP(COuter)
...
COM_INTERFACE_ENTRY_AUTOAGGREGATE(IID_IAutoAgg, m_pUnkAutoAgg.p, CLSID_CAutoAgg)
...
END_COM_MAP()
