Starting,
Pausing, and Resuming Playback
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 MCIWndPauseLGL3.T 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.
