Arguments: device &key quantity-p name-p open-only-p install-name-p

Returns a string or number containing descriptive information about the MCI device as requested by the keyword arguments. Exactly one of quantity-p, name-p, or install-name-p should be passed as true.

If quantity-p is true, then the number of devices of the same type as device is returned as an integer. If open-only-p is nil then this is the number of such devices that are listed in the registry; if open-only-p is true then this is the number of such devices that are currently open.

If name-p is true, then a device name or names are returned as a string. If open-only-p is true, then the names for all of the currently open devices are returned. If open-only-p is nil, then the device name for the type of device is returned.

If install-name-p is true, then the name of the type of device of mci-device (listed in the registry or the system.ini file) that was used to install the device is returned.
