This version includes support for /dev/poll so that libevent now supports all
fast event mechanisms. It also improves the portability across operating
systems.
Changes:
0.8:
* Buffered event abstraction to make writing network applications
easier; see libio for the predecessor of this idea.
0.7c:
* Bug fixes in Linux epoll and poll support.
0.7b:
* 3-clause BSD-license.
* Experimental support for real-time signals. Likely to be buggy.
* Experimental support for Windows from Mike Davis.
0.7:
* Requires level-triggered epoll patch for Linux epoll support.
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.
libevent is meant to replace the asynchronous event loop found in event
driven network servers. An application just needs to call event_dispatch()
and can then add or remove events dynamically without having to change the
event loop.
Currently, libevent supports kqueue(2) and select(2). Support for poll(2)
and /dev/poll is planned. The internal event mechanism is completely
independent of the exposed event API, and a simple update of libevent can
provide this new functionality without having to redesign the server
applications.
