MCI_CLOSE
The MCI_CLOSE
command releases access to a device or file. All devices recognize this
command.
MCIERROR mciSendCommand(MCIDEVICEID wDeviceID,
MCI_CLOSE,
DWORD dwFlags, (DWORD)
(LPMCI_GENERIC_PARMS) lpClose);
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.
lpClose
Address of an
MCI_GENERIC_PARMS
structure. (You can also use an MCI_CLOSE_PARMS structure. For more information, see the
comments for MCI_GENERIC_PARMS.)
Return Values
Returns zero
if successful or an error otherwise.
Remarks
Exiting an
application without closing any MCI devices it has opened can leave the device
inaccessible. Your application should explicitly close each device or file when
it is finished with it. MCI unloads the device when all instances of the device
or all associated files are closed.
