Processing the MM_WOM_DONE Message

The following example shows how to process the MM_WOM_DONE 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);

}
