Implement this interface to recieve a callback when rendering has completed on the IRenderEngine this interface is attached to. IRenderEngine::SetRenderCallback() should be called initiate this exchange.

Member Function Documentation

virtual signed int IRenderEngineCallback::AskInterface ( const BGUID *  piid, IRoot **  ppr  )

pure virtual

Queries this object to see if the interface piid is supported and returns the result in ppr.

Parameters

piid	The BGUID of the requested interface.
ppr	The address of an IRoot pointer which will receive the new interface.

Returns

S_OK if the interface is supported. E_FAIL if it is not.

Implements IRoot.

virtual signed int IRenderEngineCallback::DecRef ( )

pure virtual

Decreases the reference count on this object by 1. If the reference count reaches 0, the object is deallocated.

Implements IRoot.

virtual signed int IRenderEngineCallback::IncRef ( )

pure virtual

Increases the reference count on this object by 1. You do not need to call this after an object is first created. It is 1 by default.

Implements IRoot.

virtual signed int IRenderEngineCallback::RenderComplete ( signed int *  id )

pure virtual

Indicates that a render has completed.

Parameters

id	Contains the value passed into IRenderEngine::SetRenderCallback().
