MCI_ANIM_PLAY_PARMS
 
        The MCI_ANIM_PLAY_PARMS structure contains parameters for the
        MCI_PLAY message for animation devices. When assigning data to
        the fields in this data structure, set the corresponding MCI
        flags in the dwFlags parameter of mciSendCommand to validate
        the fields. You can use the MCI_PLAY_PARMS data structure in
        place of MCI_ANIM_PLAY_PARMS if you are not using the extended
        data fields.
