Pidgin Query

[Jeff Sadowski]

here is a demonstration of using jna :-)

wget https://jna.dev.java.net/source/browse/*checkout*/jna/trunk/jnalib/dist/jna.jar
cat << END > hello.c
int hello()
{
 return 5;
}
END
gcc -shared -o libhello.so hello.c
PWD=`pwd`
export CLASSPATH=.:jna.jar
cat << END > hellow.java
import com.sun.jna.*;
import java.util.*;
class hellow
{
 String oldclasspath = System.setProperty("java.class.path","$PWD");
 public interface helloworld extends Library {
 int hello();
 }
 public static void main(String[] args)
 {
 String oldjnalibpath = System.setProperty("jna.library.path","$PWD");
 helloworld lib = (helloworld)Native.loadLibrary("hello",helloworld.class);
 System.out.println(lib.hello());
 }
}
END
javac hellow.java
java hellow
