MCI_WAVE_OPEN_PARMS
 
        The MCI_WAVE_OPEN_PARMS structure contains information for
        MCI_OPEN message for waveform audio 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_OPEN_PARMS data structure in place of MCI_WAVE_OPEN_PARMS
        if you are not using the extended data fields.
