| Return code | Description |
|---|---|
|
The method was successful. |
Remarks
Each client can have at most one IDebugOutputCallbacks or IDebugOutputCallbacksWide object registered with it for output.
If no output callbacks object is registered with the client, the value of Callbacks will be set to NULL.
The IDebugOutputCallbacks interface extends the COM interface IUnknown. Before returning the IDebugOutputCallbacks 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.
