The libevent API provides a mechanism to execute a callback function when a specific event occurs on a file descriptor or after a timeout has been reached. It is meant to replace the asynchronous event loop found in event-driven network servers. License: BSD License (revised) Changes: This release contains a new RPC subsystem that makes it easy to write distributed servers and clients. Almost everything is documented via Doxygen now. There have been a bunch of fixes and improvements to evdns and evhttp. Libevent now builds two additional libraries: libevent_core (containing only the event core) and libevent_extras (contained evdns, evhttp, and evrpc). Performance was slightly improved due to using a heap instead of red-black trees for timeouts. Finally, Solaris' event ports are better supported.
