| Return code | Description |
|---|---|
|
The method was successful. |
Remarks
Each client can have at most one IDebugEventCallbacks or IDebugEventCallbacksWide object registered with it for receiving events.
If no event callbacks object is registered with the client, the value of Callbacks will be set to NULL.
The IDebugEventCallbacks interface extends the COM interface IUnknown. Before returning the IDebugEventCallbacks object specified by Callbacks, the engine calls its IUnknown::AddRef method. When this object is no longer needed, its IUnknown::Release method should be called.
For more information about callbacks, see Callbacks.
