Microsoft DirectX 8.0 (C++)

IDirectMusicTool8::Init

Initializes the tool. This method is called when the tool is inserted into the graph, giving the tool an opportunity to perform any necessary initialization.

HRESULT Init(
  IDirectMusicGraph* pGraph
);

Parameters

pGraph
Calling graph.

Return Values

Return values are determined by the implementation. If the method succeeds, it returns S_OK. If it fails, the method can return one of the following error values:

E_FAIL
E_NOTIMPL

Remarks

Because a tool can be inserted into more than one graph, this method must be able to deal gracefully with multiple calls.

Be sure not to create a circular reference to the graph represented by pGraph. For more information, see DirectMusic Tools.
