Pointer to the ITransition2 interface object.
nOffset
[in]:
Specifies the new step offset.
pnStatus
[out]:
Used to track the state of the transition.
Interface
Prototype
  •    AEERESULT ITransition2_Step(ITransition2* pif, int nOffset, int *pnStatus) 
    
Return
  •    AEE_SUCCESS         :  The transition step successfully.
       AEE_EFAILED         :  Transition failed to step.
    
Side Effect

Comments
nStatus is set to ITransition2_STATUS_STEP_DONE if the transition has completed, otherwise it will be set to ITransition2_STATUS_STEP_MORE. The transition manager will use this status to determine whether or not the transition needs to be re- queued.
