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.

History

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.
