Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

WODM_RESET
 
        This message is sent to a waveform output device driver to stop
        playback of a waveform and return all data blocks in the
        playback queue to the client.
 
Parameters
        DWORD dwParam1
            Unused.
 
        DWORD dwParam2
            Unused.
 
Return value
        The return value is an error code, or zero (MMSYSERR_NOERROR) if
        the operation is successful. Possible error codes are:
 
        MMSYSERR_NOTENABLED
            The driver failed to load or initialize.
 
Comments
        If the driver is playing or paused, it should stop and mark all
        pending data blocks as done by setting the WHDR_DONE bit in the
        dwFlags field of the WAVEHDR structure for each block. The
        driver should then notify the client by using DriverCallback to
        send a WOM_DONE message for each data block. If playback was
        paused, the driver should take itself out of the paused state.
        The driver should reset its position count to zero.
