而jint是以JNI为中介使JAVA的int类型与本地的int沟通的一种类型，我们可以视而不见，就当做int使用。 函数的名称是JAVA_再加上java程序的package路径再加函数名组成的。

当然，如果有更好的方法也希望大家提出。 到这里，一个完整的Java通过JNI调用动态链接库的程序就完成了。 实际上也不是很复杂。 只要多注意一下细节，是很容易得出来的。

Since my trusty C++ compiler produced fast math code, I just needed to call these math routines instead of the slow StrictMath routines from my Java program. Java Native Interface (JNI) enables ...

I would like to have some JNI code malloc a block of memory and pass it back to my Java code (in the form of a jlong), so that future calls to other JNI functions can pass this pointer along for ...

JNI was introduced in JDK 1.1, which dates back to February 1997, as the primary means for interoperating between Java code and native code, typically written in C. The interface allows Java code ...
