[systemd-devel] Udev development questions

[Marek]

Hi,

I'd like to ask a couple of questions:
1. Does udev store its list as a simple single or double linked list
or key value database? Does udev store it on disk or in memory?
2. Where can I find description of subsystem devtype string values?
struct udev_device * udev_device_get_parent_with_subsystem_devtype

                                                        (struct
udev_device *udev_device,
                                                         const char *subsystem,
                                                         const char *devtype);
