COM_INTERFACE_ENTRY_AUTOAGGREGATE_BLIND

  • 项目

Same as COM_INTERFACE_ENTRY_AUTOAGGREGATE, except that querying for any IID results in forwarding the query to punk, and if punk is NULL, automatically creating the aggregate described by the clsid.

COM_INTERFACE_ENTRY_AUTOAGGREGATE_BLIND( punk, clsid )

Parameters

  • 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

If the interface query fails, processing of the COM map continues.

See COM_INTERFACE_ENTRY Macros for remarks about COM map entries.

Example

BEGIN_COM_MAP(COuter4)
   COM_INTERFACE_ENTRY_AUTOAGGREGATE_BLIND(m_punkAutoAggB, CLSID_CAutoAggB)
END_COM_MAP()
