The caller is responsible to drop this reference when done. On failure, NULL is returned. On success, udev_monitor_enable_receiving() and udev_monitor_set_receive_buffer_size() return an integer greater than, or equal to, 0. On failure, a negative error code is returned. On success, udev_monitor_get_fd() returns the file descriptor used by this monitor. On failure, a negative error code is returned. udev_monitor_get_udev() always returns a pointer to the udev context that this monitor is associated with. udev_new3, udev_device_new_from_syspath3, udev_enumerate_new3, udev_monitor_new_from_netlink3, udev_monitor_filter_update3, udev_list_entry3, systemd1,
