请教大家一个关于jna调用中，遇到结构体指针的问题。

[jane_zhao]

// Original C code
typedef struct _Point
{ int x, y;
} Point;

Point* translate(Point* pt, int dx, int dy);

// Equivalent JNA mapping

class Point extends Structure
{ public int x, y; }

Point translate(Point pt, int x, int y);
...
Point pt = new Point();
Point result = translate(pt, 100, 100);

以上是JNA API Documentation 里的实现方式，依次类推，如果C这边的函数类似：

struct nn_pollfd {
    int fd;
    short events;
    short revents;
};
int nn_poll (struct nn_pollfd *fds, int nfds, int timeout);

那我写的java代码则为：

public class nn_pollfd extends Structure{
   public int fd;
     public  short events;
     public  short revents;
}
int nn_poll (nn_pollfd fds, int nfds, int timeout);

我的问题出来了，C这边为结构体指针，可以传入多组结构体值，例如：

struct nn_polld pfd [2];
pfd [0].fd = s1;
pfd [0].events = NN_POLLIN | NN_POLLOUT;
pfd [1].fd = s2;
pfd [1].events = NN_POLLIN;
rc = nn_poll (pfd, 2, 2000);
if (rc == 0) {
    printf ("Timeout!");
    exit (1);
}
if (rc == -1) {
    printf ("Error!");
    exit (1);
}
if (pfd [0].revents & NN_POLLIN) {
    printf ("Message can be received from s1!");
    exit (1);
}

但对应到java这边，第一个参数只是一个类而非类的数组，那只能传入一组值，java这边怎么办？
在线等，谢谢！

有人在吗？怎么没人帮我啊？谢谢！

我觉得int nn_poll (nn_pollfd fds, int nfds, int timeout); 错误了，声明应该为int nn_poll (Pointer fds, int nfds, int timeout);或者int nn_poll (nn_pollfd.Byreference fds, int nfds, int timeout);
