MCI_ESCAPE (VIDEODISC)
 
        This MCI command message sends a string directly to the
        device. This message is part of the videodisc command set. The
        parameters and flags for this message vary according to the
        selected device.
 
Parameters
        DWORD dwFlags
            The following flags apply to all devices supporting
            MCI_ESCAPE:
 
            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 field of the data
                structure identified by lpEscape
 
            MCI_WAIT
                Specifies that the operation should finish before MCI
                returns control to the application.
 
            MCI_VD_ESCAPE_STRING
                Indicates a command string is specified in the
                lpstrCommand field of the data structure identified by
                lpEscape. This flag is required.
 
        LPMCI_VD_ESCAPE_PARMS lpEscape
            Specifies a far pointer to the MCI_VD_ESCAPE_PARMS data
            structure. (Devices with extended command sets might
            replace this data structure with a device-specific data
            structure.)
 
Comments
        The data sent with MCI_ESCAPE is device dependent and is
        usually passed directly to the hardware associated with the
        device.
 
Return value
        Returns zero if successful. Otherwise, it returns an MCI error
        code.
