protected: inline MMMFAudioOutput();

Description

Protected constructor.

static inline MMMFAudioOutput *NewAudioOutputL(TUid aImplementationUid, const TDesC8 &aInitData);

Description

Gets a new audio output object.

Parameters

TUid aImplementationUid The implementation UID. const TDesC8 &aInitData The initialisation data.

Return value

MMMFAudioOutput * The audio output object.

virtual CMMFDevSound &SoundDevice()=0;

Description

Returns the sound device.

Accessor function exposing public CMMFDevsound methods.

Return value
