Invoking native C/C++ libs using clojure and JNA

So as a continuation of the last post http://orphanware.blogspot.com/2012/08/making-c-available-through-native-calls.html....here is how you do it in clojure download jna.jar and platform.jar write clojures codes!

(defn helloworld ( []
                ( let [ lib  ( com.sun.jna.NativeLibrary/getInstance "mylib" ) ]
                ( let [ helloWorld ( .getFunction lib  "MYLIB_helloWorld" ) ]
                ( println ( .invokeVoid helloWorld null ) ) ) ) ) )

( helloworld )

then run with

java -cp /usr/share/java/clojure.jar:jna.jar:. -Djna.nosys=true clojure.main helloworld.clj
