MODM_RESTART

Sent to a MIDI output device driver to restart playback after a MODM_PAUSE.

Returns zero if the operation is successful. Otherwise, it returns an error number. Possible error values include the following:

MMSYSERR_NOTENABLED

The driver failed to load or initialize.

dwParam1: Unused.
dwParam2: Unused.

The driver should resart MIDI playback at the current position.

MODM_PAUSE/MODM_RESTART pairs cannot be nested. MODM_PAUSE messages received while already in the paused state should be ignored; playback will start on the first MODM_RESTART message received regardless of how many MODM_PAUSE messages where received. Likewise, MODM_RESTART messages received while already playing should be ignored. MMSYSERR_NOERROR should be returned in either case.
