768<p>TBD.</p> 768<p>Libev offers a compatibility emulation layer for libevent. It cannot
769emulate the internals of libevent, so here are some usage hints:</p>
770<dl>
771 <dt>* Use it by including &lt;event.h&gt;, as usual.</dt>
772 <dt>* The following members are fully supported: ev_base, ev_callback,
773ev_arg, ev_fd, ev_res, ev_events.</dt>
774 <dt>* Avoid using ev_flags and the EVLIST_*-macros, while it is
775maintained by libev, it does not work exactly the same way as in libevent (consider
776it a private API).</dt>
777 <dt>* Priorities are not currently supported. Initialising priorities
778will fail and all watchers will have the same priority, even though there
779is an ev_pri field.</dt>
780 <dt>* Other members are not supported.</dt>
781 <dt>* The libev emulation is <i>not</i> ABI compatible to libevent, you need
782to use the libev header file and library.</dt>
