JNA中怎么模拟这个结构体，解决再加分！！急！！！！！！

[wsnangua]

typedef struct _PCI_COMMON_CONFIG {
USHORT VendorID;
USHORT DeviceID;
USHORT Command;
USHORT Status;
UCHAR RevisionID;
UCHAR ProgIf;
UCHAR SubClass;
UCHAR BaseClass;
UCHAR CacheLineSize;
UCHAR LatencyTimer;
UCHAR HeaderType;
UCHAR BIST;
union {
struct {
ULONG BaseAddresses[6];
ULONG Reserved1[2];
ULONG ROMBaseAddress;
ULONG Reserved2[2];
UCHAR InterruptLine;
UCHAR InterruptPin;
UCHAR MinimumGrant;
UCHAR MaximumLatency;
} type0;
} u;
UCHAR DeviceSpecific[192];
} PCI_COMMON_CONFIG, *PPCI_COMMON_CONFIG;

其中
typedef unsigned short USHORT;
typedef unsigned char UCHAR;
typedef unsigned long ULONG;

这个结构体在java中怎么对应？我用的JNA，急~~~~~~~~~~~

mark，学习，帮顶

谢谢帮顶的大家，我用的是JNA，直接调用dll，不用自己写dll文件了~~~ 看了网上的参考资料，我对应的java部分如下：

	public static class pciConfig extends Structure {

		public static class ByReference extends pciConfig implements
				Structure.ByReference {
		}

		public static class ByValue extends pciConfig implements
				Structure.ByValue {
		}
				
		public short VendorID;
		public short DeviceID;
		public short Command;
		public short Status;
		public byte RevisionID;
		public byte ProgIf;
		public byte SubClass;
		public byte BaseClass;
		public byte CacheLineSize;
		public byte LatencyTimer;
		public byte HeaderType;
		public byte BIST;
		
		public static class type0 extends Structure {

			public static class ByReference extends type0 implements
					Structure.ByReference {
			}
			public static class ByValue extends type0 implements
					Structure.ByValue {
			}
			public NativeLong[] BaseAddresses = new NativeLong[3];
			public NativeLong[] Reserved1 = new NativeLong[2];
			public NativeLong ROMBaseAddress;
			public NativeLong[] Reserved2 = new NativeLong[2];
			public byte InterruptLine;
			public byte InterruptPin;
			public byte MinimumGrant;
			public byte MaximumLatency;
		}

		public static class union extends Union {

			public static class ByReference extends union implements
					Union.ByReference {
			}
			public static class ByValue extends union implements Union.ByValue {
			}
			public type0 typ;
		}
		public union u;
		public byte[] DeviceSpecific = new byte[192];

	}

但是老是报错，网上的例子中结构体都木有这么复杂，我不知道这种嵌套的怎么写，有木有JNA高手呀，求解惑！！！

你直接把这个structure当成一个byte[]来处理吧

[hbwhwang]

先在C里面把PCI_COMMON_CONFIG sizeof一下，看看多少个byte，就在JAVA里面 new byte[size]。 你自己心里得清楚这个数组中每个字节对应的PCI_COMMON_CONFIG中的属性。

唉 现在CSDN这么冷清。。。。最终还是自己解决了，不过还是谢谢楼上的TX~
