# LEV
LEV is [libev](http://software.schmorp.de/pkg/libev.html) bindings for Common Lisp.
## Usage
“‘common-lisp
(ql:quickload :lev)
(cffi:defcallback stdin-cb :void ((evloop :pointer) (io :pointer) (revents :int))
(declare (ignore revents))
(format t "stdin ready~%")
(lev:ev-io-stop evloop io))
(cffi:defcallback timeout-cb :void ((evloop :pointer) (timer :pointer) (revents :int))
(declare (ignore timer revents))
(format t "timeout~%")
(lev:ev-break evloop lev:+EVBREAK-ONE+))
(let ((evloop (lev:ev-default-loop 0))
(stdin-watcher (cffi:foreign-alloc ’(:struct lev:ev-io)))
(timeout-watcher (cffi:foreign-alloc ’(:struct lev:ev-timer))))
(unwind-protect
(progn
;; initialize an io watcher, then start it
;; this one will watch for stdin to become readable
(lev:ev-io-init stdin-watcher ’stdin-cb 0 lev:+EV-READ+)
(lev:ev-io-start evloop stdin-watcher)
;; initialize a timer watcher, then start it
;; simple non-repeating 5.5 second timeout
(lev:ev-timer-init timeout-watcher ’timeout-cb 5.5d0 0d0)
(lev:ev-timer-start evloop timeout-watcher)
(format t "running~%")
(lev:ev-run evloop 0))
(cffi:foreign-free stdin-watcher)
(cffi:foreign-free timeout-watcher)))

## Why not cl-ev?
We already have [cl-ev](https://github.com/sbryant/cl-ev) for libev bindings, however I found there’s some problems in it.
* Wrapping with CLOS. It’s bad for performance, obviously
* Incomplete API
* The author is inactive in Common Lisp world anymore
## See Also
* [libev’s documentation](http://pod.tst.eu/http://cvs.schmorp.de/libev/ev.pod)
