IAVTransportImpl (Windows Embedded CE 6.0)
1/6/2010
This class derives from the pure virtual IAVTransport class and provides do-nothing implementations for all methods that correspond to optional actions in the AVTransport DCP.
Syntax
class IAVTransportImpl : public IAVTransport
Methods
This class inherits methods defined in the IAVTransport interface. It defines no additional methods.
Remarks
UPnP AV devices usually provide AVTransport functionality by creating a class that derives from this class.
Because this class provides implementations for all methods that correspond to optional actions in the AVTransport DCP, custom code only needs to provide implementations for required AVTransport 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 AVTransport DCP, see UPnP AV DCP Documentation.
