MCI_STOP

See also MCI_PAUSE, MCI_PLAY, MCI_RECORD, MCI_RESUME

Stops all play and record sequences, unloads all play buffers, and ceases display of video images. Support of this message by a device is optional. The parameters and flags for this message vary according to the selected device.

Returns zero if successful. Otherwise, it returns an MCI error code.

DWORD lParam1

The following flags apply to all devices supporting MCI_STOP:

MCI_NOTIFY	Specifies that MCI should post the MM_MCINOTIFY message when this command completes. The window to receive this message is specified in the dwCallback member of the structure identified by lpStop.
MCI_WAIT	Specifies that the device should stop before MCI returns control to the application.

LPMCI_GENERIC_PARMS lParam2

Specifies a far pointer to the MCI_GENERIC_PARMS structure. (Devices with extended command sets might replace this structure with a device-specific structure.)

The difference between MCI_STOP and MCI_PAUSE depends upon the device. If possible, MCI_PAUSE suspends device operation but leaves the device ready to resume play immediately.
