Same as COM_INTERFACE_ENTRY_FUNC, except that querying for any IID results in a call to func.
[in] A parameter passed through to the func.
[in] The function that gets called when this entry in the COM map is processed.
Any failure will cause processing to continue on the COM map. If the function returns an interface pointer, it should return S_OK.
See COM_INTERFACE_ENTRY Macros for remarks about COM map entries.
