On success,
udev_enumerate_scan_devices(),
udev_enumerate_scan_subsystems() and
udev_enumerate_add_syspath()
return an integer greater than, or equal to,
0.
On success,
udev_enumerate_get_list_entry()
returns a pointer to the first entry in the list of found
devices. If the list is empty, or on failure,
NULL is returned.
udev_enumerate_get_udev() always
returns a pointer to the udev context that this enumerated
object is associated with.
udev_enumerate_scan_devices(),
udev_enumerate_scan_subsystems(),
udev_enumerate_get_list_entry(),
udev_enumerate_add_syspath(), and
udev_enumerate_get_udev() were added in version 221.
