MCIWndPlay is the most general playback macro. This macro lets you play a file or device from the current playback position. Playback continues through the end of the content unless it is interrupted.
You can temporarily interrupt a device that is playing by using the MCIWndPause macro. To resume playback from the paused position, use the MCIWndResume macro. Some devices do not support the pause and resume commands. These devices usually map MCIWndPause to the MCIWndStop macro, which stops playback or recording. You can restart a device that does not support pause or resume by using MCIWndPlay, which starts playback from the current playback position.
