Comments

A user-mode waveform input driver sends a WOM_CLOSE message to its client, by means of a callback, when the driver finishes processing a WODM_CLOSE message. The driver sends the message to the client by calling DriverCallback, passing the specified parameters.

The driver sends the WOM_CLOSE message only if the client has previously specified a notification target with a WODM_OPEN message.

Win32 SDK documentation states that clients receive an MM_WOM_CLOSE message if the notification target is a window handle. WOM_CLOSE and MM_WOM_CLOSE are equivalent.
