Return Values
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 errors documented for this action in the AVTransport DCP documentation:
- ERROR_AV_UPNP_AVT_INVALID_TRANSITION
- ERROR_AV_UPNP_AVT_TRANSPORT_LOCKED
- ERROR_AV_UPNP_AVT_ILLEGAL_SEEK_TARGET
- ERROR_AV_UPNP_AVT_INVALID_INSTANCE_ID

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