在GetProcessMemoryInfo（）中使用指针

Question

有我的代码：

    import com.sun.jna.Native;
        PROCESS_MEMORY_COUNTERS pmem = new PROCESS_MEMORY_COUNTERS();
        boolean success = PSAPI.GetProcessMemoryInfo(kernel32.GetCurrentProcess(), pmem, pmem.size());
                        if (!success){
                                int err=Native.getLastError();
                    System.out.println("GetProcessMemoryInfo failed:" + err);
        }

结构是PSAPI级：

public static class PROCESS_MEMORY_COUNTERS extends Structure {
    public int cb;
    public int PageFaultCount;
    public int PeakWorkingSetSize;
    public int WorkingSetSize;
    public int QuotaPeakPagedPoolUsage;
    public int QuotaPagedPoolUsage;
    public int QuotaPeakNonPagedPoolUsage;
    public int QuotaNonPagedPoolUsage;
    public int PagefileUsage;
    public int PeakPagefileUsage;

    @Override
    protected List getFieldOrder() {
        return null;
    }
}

PSAPI级声明：

boolean GetProcessMemoryInfo(Pointer process, int pmem, int cb);

这段代码是否正确？

GetProcessMemoryInfo（）函数需要指向 pmem 变量的指针，但我不知道如何在Java中实现这个指针：PSAPI.GetProcessMemoryInfo(kernel32.GetCurrentProcess(), pmem, pmem.size());

我希望你的帮助。谢谢！
