IAudioChannelConfig::SetChannelConfig method

The SetChannelConfig method sets the channel-configuration mask in a channel-configuration control.

Syntax


HRESULT SetChannelConfig(
  [in] DWORD   dwConfig,
  [in] LPCGUID pguidEventContext
);

Parameters

dwConfig [in]

The channel-configuration mask.

pguidEventContext [in]

Context value for the IControlChangeNotify::OnNotify method. This parameter points to an event-context GUID. If the SetChannelConfig call changes the state of the channel-configuration control, all clients that have registered IControlChangeNotify interfaces with that control receive notifications. In its implementation of the OnNotify method, a client can inspect the event-context GUID to discover whether it or another client is the source of the control-change event. If the caller supplies a NULL pointer for this parameter, the client's notification method receives a NULL context pointer.

Return value

If the method succeeds, it returns S_OK. If it fails, possible return codes include, but are not limited to, the values shown in the following table.
