<p>Libev offers a compatibility emulation layer for libevent. It cannot |
|
|
|
|
emulate the internals of libevent, so here are some usage hints:</p> |
|
|
|
|
<dl> |
|
|
|
|
<dt>* Use it by including <event.h>, as usual.</dt> |
|
|
|
|
<dt>* The following members are fully supported: ev_base, ev_callback, |
|
|
|
|
ev_arg, ev_fd, ev_res, ev_events.</dt> |
|
|
|
|
<dt>* 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).</dt> |
|
|
|
|
<dt>* 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.</dt> |
|
|
|
|
<dt>* Other members are not supported.</dt> |
|
|
|
|
<dt>* The libev emulation is <i>not</i> ABI compatible to libevent, you need |
|
|
|
|
to use the libev header file and library.</dt> |
