Reversing Playback

Some devices support playback in the reverse direction. You can play the content of such a device in the reverse direction by using the MCIWndPlayReverseB4C6VZ macro. This macro defines the playback scope from the current playback position to the beginning of the content. The digital-video device, MCIAVI.DRV, can play backward. Devices that cannot play backward, such as CD audio, can issue an error message when MCIWndPlayReverse is invoked.
