LIBEVENT EMULATION

Top

-

TBD.

+

Libev offers a compatibility emulation layer for libevent. It cannot +emulate the internals of libevent, so here are some usage hints:

+
+
* Use it by including <event.h>, as usual.
+
* The following members are fully supported: ev_base, ev_callback, +ev_arg, ev_fd, ev_res, ev_events.
+
* Avoid using ev_flags and the EVLIST_*-macros, while it is +maintained by libev, it does not work exactly the same way as in libevent (consider +it a private API).
+
* Priorities are not currently supported. Initialising priorities +will fail and all watchers will have the same priority, even though there +is an ev_pri field.
+
* Other members are not supported.
+
* The libev emulation is not ABI compatible to libevent, you need +to use the libev header file and library.
