MCI_ESCAPE command
The MCI_ESCAPE command sends a string directly to the device. Videodisc devices recognize this command.
To send this command, call the mciSendCommand function with the following parameters.
MCIERROR mciSendCommand(
MCIDEVICEID wDeviceID,
MCI_ESCAPE,
DWORD dwFlags,
(DWORD) (LPMCI_VD_ESCAPE_PARMS) lpEscape
);
Parameters
-
wDeviceID
-
Device identifier of the MCI device that is to receive the command message.
-
dwFlags
-
MCI_NOTIFY or MCI_WAIT. For information about these flags, see The Wait, Notify, and Test Flags.
-
lpEscape
-
Pointer to an MCI_VD_ESCAPE_PARMS structure.
Return Value
Returns zero if successful or an error otherwise.
Remarks
The data sent with MCI_ESCAPE is device-dependent and is usually passed directly to the hardware associated with the device.
The following additional flag applies to videodisc devices:
-
MCI_VD_ESCAPE_STRING
-
A command string is specified in the lpstrCommand member of the structure identified by lpEscape. This flag is required.
