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

DWORD lParam1

The following flags apply to all devices supporting MCI_COMMAND:

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 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 member of the structure identified by lpEscape. This flag is required.

LPMCI_VD_ESCAPE_PARMS lParam2

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

The data sent with MCI_ESCAPE is device dependent and is usually passed directly to the hardware associated with the device.
