MCI_UNDO command
The MCI_UNDO command reverses the most recent successful MCI_CUT, MCI_COPY, MCI_DELETE, or MCI_PASTE command. Digital-video devices recognize this command.
To send this command, call the mciSendCommand function with the following parameters.
MCIERROR mciSendCommand(
MCIDEVICEID wDeviceID,
MCI_UNDO,
DWORD dwFlags,
(DWORD) (LPMCI_GENERIC_PARMS) lpUndo
);
Parameters

MCI_NOTIFY, MCI_WAIT, or MCI_TEST. For information about these flags, see The Wait, Notify, and Test Flags.
-

Pointer to an MCI_GENERIC_PARMS structure. (Devices with extended command sets might replace this structure with a device-specific structure.)
