带有附加参数的JNA回调函数

import com.sun.jna.Callback;
import com.sun.jna.Pointer;

public interface MyCallback extends Callback {
    void callbackFunction(int param1, float param2, Pointer additionalParam);
}

public class MyCallbackProxy implements MyCallback {
    private Pointer additionalParam;

    public MyCallbackProxy(Pointer additionalParam) {
        this.additionalParam = additionalParam;
    }

    @Override
    public void callbackFunction(int param1, float param2, Pointer additionalParam) {
        // 在这里使用传递的参数进行处理
    }
}

public class Main {
    public static void main(String[] args) {
        Pointer additionalParam = new Pointer(123); // 创建附加参数
        MyCallback callback = new MyCallbackProxy(additionalParam); // 创建回调函数实例
        // 将回调函数传递给本地代码进行调用
        NativeLibrary.myNativeFunction(callback);
    }
}
