COM Map Macros

These macros define COM interface maps.

BEGIN_COM_MAP	Marks the beginning of the COM interface map entries.
COM_INTERFACE_ENTRY	Enters interfaces into the COM interface map.
COM_INTERFACE_ENTRY2	Use this macro to disambiguate two branches of inheritance.
COM_INTERFACE_ENTRY_IID	Use this macro to enter the interface into the COM map and specify its IID.
COM_INTERFACE_ENTRY2_IID	Same as COM_INTERFACE_ENTRY2, except you can specify a different IID.
COM_INTERFACE_ENTRY_AGGREGATE	When the interface identified by iid is queried for, COM_INTERFACE_ENTRY_AGGREGATE forwards to punk.
COM_INTERFACE_ENTRY_AGGREGATE_BLIND	Same as COM_INTERFACE_ENTRY_AGGREGATE, except that querying for any IID results in forwarding the query to punk.
COM_INTERFACE_ENTRY_AUTOAGGREGATE	Same as COM_INTERFACE_ENTRY_AGGREGATE, except if punk is NULL, it automatically creates the aggregate described by the clsid.
COM_INTERFACE_ENTRY_AUTOAGGREGATE_BLIND	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_BREAK	Causes your program to call DebugBreak when the specified interface is queried for.
COM_INTERFACE_ENTRY_CACHED_TEAR_OFF	Saves the interface-specific data for every instance.
COM_INTERFACE_ENTRY_TEAR_OFF	Exposes your tear-off interfaces.
COM_INTERFACE_ENTRY_CHAIN	Processes the COM map of the base class when the processing reaches this entry in the COM map.
COM_INTERFACE_ENTRY_FUNC	A general mechanism for hooking into ATL's QueryInterface logic.
COM_INTERFACE_ENTRY_FUNC_BLIND	Same as COM_INTERFACE_ENTRY_FUNC, except that querying for any IID results in a call to func.
COM_INTERFACE_ENTRY_NOINTERFACE	Returns E_NOINTERFACE and terminates COM map processing when the specified interface is queried for.
END_COM_MAP	Marks the end of the COM interface map entries.
