The Close method closes a DirectMusic "port", which is a DirectMusic term for a device that sends or receives music data.
Syntax
HRESULT Close();
Return value
Close returns S_OK if the call was successful. Otherwise, the method returns an appropriate error code. The following table shows some of the possible return status codes.
| Return code | Description |
|---|---|
|
Indicates that the port was not open. |
Remarks
This method closes a DirectMusic "port" that was previously opened by a call to IDirectMusicSynth::Open.
When the DirectMusic "port" closes, it automatically releases all instruments and waves that were previously downloaded to the port. However, a good practice for applications is to explicitly free these objects before closing the port.
Avoid confusing the term DirectMusic "port" with a DMus port driver. A DirectMusic port corresponds to a render or capture pin on a DirectMusic filter. For more information about DirectMusic ports, see the description of the IDirectMusicPort interface in the Microsoft Windows SDK documentation.
