IDebugEventCallback2
This interface is used by the debug engine (DE) to send debug events to the session debug manager (SDM).
Syntax
IDebugEventCallback2 : IUnknown
Notes for Implementers
Visual Studio implements this interface to receive events from a debug engine.
Notes for Callers
A debug engine typically receives this interface when the SDM calls Attach, Attach, or LaunchSuspended. A debug engine sends events to the SDM by calling Event.
Methods in Vtable Order
The following table shows the methods of IDebugEventCallback2.
| Method | Description |
|---|---|
| Event | Sends notification of debugging events to the SDM. |
Remarks
Although EvaluateSync and EvaluateAsync specify that they take an IDebugEventCallback2 interface, this is not the case, and the interface pointer will always be a null value. Instead, the debug engine must use the IDebugEventCallback2 interface received in the call to Attach, Attach, or LaunchSuspended.
If a package implements IDebugEventCallback in managed code, it is strongly advised that ReleaseComObject be invoked on the various interfaces that are passed to Event.
