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.
