Microsoft DirectX 8.0 (C++) |
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 );
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 |
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.
