| Return code | Description |
|---|---|
|
The method was successful. |
Remarks
Each client can have at most one event callback registered with it. When a callback is registered with a client, its IDebugEventCallbacks::GetInterestMask method is called to allow the client to specify which events it is interested in.
For more information about callbacks, see Callbacks.
