ATL END_COM_MAP macro is defined as follows: #define END_COM_MAP() \\ __if_exists(_GetAttrEntries) {{NULL, (DWORD_PTR)_GetAttrEntries, _ChainAttr }, }\\
In ATL there\'s a BEGIN_COM_MAP macro for declaring a table that controls how the QueryInterface() behaves when called on the corresponding class object.
Seems like both COM_INTERFACE_ENTRY_IID and COM_INTERFACE_ENTRY2_IID are for the case when the class is derived from two or more classes each derived from a common interface. Like this:
Closed. This question does not meet Stack Overflow guidelines. It is not currently accepting answers.
ATL provides a bunch of macros for creating so-called COM maps - chains of rules of how the QueryInterface() call behaves on a given object. The map begins with BEGIN_COM_MAP and ends with END_COM_MAP
or a VB6 - compatible - collection object. We provide hooks into ou开发者_Python百科r .net products through a set of API\'s.
