The GetOutputCallbacks method returns the output callbacks object registered with the client.

Syntax

HRESULT GetOutputCallbacks(
  [out] PDEBUG_OUTPUT_CALLBACKS *Callbacks
);

Parameters

[out] Callbacks

Receives an interface pointer to the IDebugOutputCallbacks object registered with the client.

Return value

Return code	Description
S_OK	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.
