WIDM_STOP

Sent to a waveform input device driver to stop waveform recording.

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.

DWORD dwParam1: Unused.
DWORD dwParam2: Unused.

If the current buffer is partially full, it should be marked as done and returned to the client. Any empty buffers in the queue should remain there. Calling this function when input is not started should have no effect and MMSYSERR_NOERROR should be returned.
