Reference class can not inherit from IAudioSessionNotification in C++
In C++, you can define a reference class that implements the IAudioSessionNotification
interface by using the Windows Runtime (WinRT) and the Component Extensions for Runtime Platforms (C++/CX). Here's an example of how to do it:
cpp#include <wrl/client.h>
#include <windows.media.audio.h>
using namespace Platform;
using namespace Windows::Media::Audio;
using namespace Microsoft::WRL;
ref class MyAudioSessionNotification : public IAudioSessionNotification
{
public:
STDMETHODIMP OnSessionCreated(IAudioSessionControl* pNewSession)
{
// Implement your logic here
return S_OK;
}
};
int main()
{
ComPtr<MyAudioSessionNotification> notification = Make<MyAudioSessionNotification>();
// Register the notification object with the audio session manager
// Rest of your code
return 0;
}
In the above example, the MyAudioSessionNotification
class is defined as a reference class (ref class
) and inherits from IAudioSessionNotification
. It overrides the OnSessionCreated
method, which is called when a new audio session is created.
To use the reference class, you need to include the necessary header files (windows.media.audio.h
in this case) and use the appropriate namespaces (Platform
, Windows::Media::Audio
, Microsoft::WRL
).
Note that this example assumes you're using the Windows Runtime and C++/CX to interact with the Windows audio session API. If you're using a different technology or framework, the implementation may vary.
