The MCI_CLOSE command releases access to a device or file. All devices recognize this command.
To send this command, call the mciSendCommand function with the following parameters.
MCIERROR mciSendCommand( MCIDEVICEID wDeviceID, MCI_CLOSE, DWORD dwFlags, (DWORD) (LPMCI_GENERIC_PARMS) lpClose );
Device identifier of the MCI device that is to receive the command message.
MCI_NOTIFY or MCI_WAIT. For information about these flags, see The Wait, Notify, and Test Flags.
Pointer to an MCI_GENERIC_PARMS structure. (You can also use an MCI_CLOSE_PARMS structure. For more information, see the comments for MCI_GENERIC_PARMS.)
Returns zero if successful or an error otherwise.
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.
