com.sun.jna.Pointer，读取字节数据

示例：读取前四个字节数据

Pointer pBuffer//返回数据HCNetSDK.REMOTECONFIGSTATUS struCfgStatus  = new HCNetSDK.REMOTECONFIGSTATUS();
struCfgStatus.write();
Pointer pCfgStatus = Pointer();
pCfgStatus.write(0, ByteArray(0, struCfgStatus.size()), 0,struCfgStatus.size());
ad();int iStatus = 0;
for(int i=0;i<4;i++)
{int ioffset = i*8;int iByte = struCfgStatus.byStatus[i]&0xff;iStatus = iStatus + (iByte << ioffset);
}public static class REMOTECONFIGSTATUS extends Structure {public byte[] byStatus = new byte[4];public byte[] byErrorCode = new byte[4];
}
