This is the High-Level Macro Service API Routines of OS/2 Multimedia subsystem.
All functions are from MCIAPI dll (which also contains REXX functions.
See "Multimedia with REXX" for more information.).
Warning: This code is alfa. Future versions of this unit will propably
not be compatible.

This function plays a multimedia data file (video, audio) using MCI commands.
hwndOwner is handle of owner window. If hwndOwner equial to zero used active
          window.
pszFile is pointer to asciiz name of data file. For compound files can be
        used 'filename+element'.
ulFlags is MCI_* flags.
pszTitle is title of generated window (e.g. for video). Ignored if not generated.
hwndViewport is handle of window for displaying video. If none, then default
             window displayed.
