MCI_INFO

This MCI command message obtains string information from a device. All devices respond to this message. The parameters and flags available for this message depend on the selected device.

Parameters DWORD lParam1 The following standard and command-specific flags apply to all devices:

MCI_NOTIFY	Specifies that MCI should post the MM_MCINOTIFY message when this command completes. The window that receives this message is specified in the dwCallback field of the data structure identified by lParam2.
MCI_TEST	Queries the device to determine if it can execute the command. The device returns an error if it is incapable of executing the command. It returns no error if it can handle the command. MCI returns control to the application without executing the command.
MCI_WAIT	Specifies that the operation should finish before MCI returns control to the application.
MCI_INFO_PRODUCT	Obtains a description of the hardware associated with a device. Devices should supply a description that identifies both the driver and the hardware used. Typically this returns manufacturer and model number. The name must be 31 characters or less.
LPMCI_INFO_PARMS lParam2	Specifies a far pointer to the MCI_INFO_PARMS data structure. (Devices with extended command sets might replace this data structure with a device-specific data structure.)
