IRenderingControlImpl (Windows Embedded CE 6.0)

1/6/2010

This class derives from the pure virtual IRenderingControl class and provides do-nothing implementations for all methods that correspond to optional actions in the RenderingControl DCP.

Syntax

class IRenderingControlImpl : public IRenderingControl

Methods

This class inherits methods defined in the IRenderingControl interface. It defines no additional methods.

Remarks

UPnP AV devices usually provide RenderingControl functionality by creating a class that derives from this class.

This class provides implementations for all methods that correspond to optional actions in the RenderingControl DCP. Therefore, custom code only needs to provide implementations for required RenderingControl methods and any optional methods it wants to implement. Optional methods that are not implemented should not be included in the XML service description document.

The do-nothing implementation for each method in this class returns ERROR_AV_UPNP_INVALID_ACTION.

For more information about the RenderingControl DCP, see UPnP AV DCP Documentation.
