MCI_STOP

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.
