IDebugOutputCallbacks2 interface (dbgeng.h)
The IDebugOutputCallbacks2 interface allows clients to receive full debugger markup language (DML) content for presentation.
This interface extends the IDebugOutputCallbacks interface, not the IDebugOutputCallbacksWide interface. Therefore, it can be passed in to the existing SetOutputCallbacks method.
The engine performs a QueryInterface for IDebugOutputCallbacks2 to see which interface the incoming output callback object supports. If the object supports IDebugOutputCallbacks2, all output will be sent through the extended IDebugOutputCallbacks2 methods.
An output object can register for both text and DML content, if it can handle them both. During output processing of the callback the engine will pick the format that reduces conversions, thus supporting both may reduce conversions in the engine. It is not necessary, though, and supporting only one format is the expected mode of operation.
The basic IDebugOutputCallbacks::Output method is not used.
Inheritance
The IDebugOutputCallbacks2 interface inherits from the IUnknown interface. IDebugOutputCallbacks2 also has these types of members:
