This message is used in an MMDRV_MESSAGE_PARAMSstructure passed to the WAV_IOControlfunction to request a waveform output driver to break an output loop that was created with a WODM_WRITE message.
Parameters
Return Values
MMSYSERR_NOERROR indicates success. Otherwise, the driver returns one of the MMSYSERR or WAVERR error values declared in the Mmsystem.h header file.
Remarks
The ACM sends the WODM_BREAKLOOP message by calling the audio driver's WAV_IOControlentry point through the DeviceIoControlfunction.
The driver should stop output of the loop buffers at the end of the next loop iteration.
If the driver receives this message and a loop is not in progress, it returns MMSYSERR_NOERROR.
