结构定义
typedef struct  {
    BYTE sSerialNumber[SERIALNO_LEN];  
    BYTE byAlarmInPortNum;        
    BYTE byAlarmOutPortNum;        
    BYTE byDiskNum;                
    BYTE byDVRType;                 
    BYTE byChanNum;                
    BYTE byStartChan;            
}NET_DVR_DEVICEINFO, *LPNET_DVR_DEVICEINFO;

函数声明：

LONG _stdcall(*NET_DVR_Login)(char *sDVRIP,WORD wDVRPort,char *sUserName,
               char *sPassword, LPNET_DVR_DEVICEINFO lpDeviceInfo);

Ctrl+F9时提示
    E2303 Type name expected
  请问如何处理结构体做参数？主要错在LPNET_DVR_DEVICEINFO lpDeviceInfo但不知如何处理
