Processing the MM_WOM_DONE Message

The following example shows how to process the MM_WOM_DONEEE2C5P message. This example assumes the application does not play multiple data blocks, so it can close the output device after playing a single data block.

// WndProc--Main window procedure.

LRESULT FAR PASCAL WndProc(HWND hWnd, UINT msg, WPARAM wParam,

    LPARAM lParam)

{ 

switch (msg)

{ 

    case MM_WOM_DONE:

    // A waveform-audio data block has been played and

    // can now be freed.

    waveOutUnprepareHeader((HWAVEOUT) wParam,

        (LPWAVEHDR) lParam, sizeof(WAVEHDR) );

    // Free hData memory.

    waveOutClose((HWAVEOUT) wParam);

    break;

    }

    return DefWindowProc(hWnd, msg, wParam, lParam);

}
