 Similar to the other two macros, this gives you the value of the default

+=item C<EV_DEFAULT_UC>, C<EV_DEFAULT_UC_>
+
+Usage identical to C<EV_DEFAULT> and C<EV_DEFAULT_>, but requires that the
+default loop has been initialised (C<UC> == unchecked). Their behaviour
+is undefined when the default loop has not been initialised by a previous
+execution of C<EV_DEFAULT>, C<EV_DEFAULT_> or C<ev_default_init (...)>.
+
+It is often prudent to use C<EV_DEFAULT> when initialising the first
+watcher in a function but use C<EV_DEFAULT_UC> afterwards.
