On success, udev_monitor_receive_device() returns a pointer to a
newly referenced device that was received via the monitor. 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.
