IAVTransport::GetCurrentTransportActions (Windows Embedded CE 6.0)

  • Article

1/6/2010

This method returns the currently valid transport actions.

Syntax

virtual DWORD GetCurrentTransportActions(
  TransportActions* pActions
) = 0;

Parameters

  • pActions
    [in, out] Pointer to a TransportActions structure that contains valid transport actions. Corresponds to the CurrentTransportActions state variable.

Return Value

Custom implementations can return appropriate error codes. Should return SUCCESS_AV if the method succeeds. Otherwise, should return an error code defined in WinError.h or UPnP.h, or one of the UPnP AV-specific return values specified in UPnPAVError, especially the following error documented for this action in the AVTransport DCP documentation:

  • ERROR_AV_UPNP_AVT_INVALID_INSTANCE_ID

Remarks

This method corresponds to the AVTransport service's GetCurrentTransportActions action.

The AVTransport service does not require that this method be implemented. The IAVTransportImpl class therefore overrides this method to return ERROR_AV_UPNP_INVALID_ACTION.

For more information about the actions in the AVTransport service, see UPnP AV DCP Documentation.

Requirements

Header av_upnp.h
Library Av_upnp.lib
Windows Embedded CE Windows CE 5.0 and later
