平台调用----封送结构体指针。
请教你   一个问题。
C定义如下：
BOOL     effnEDClientCheckPointInfoByTime(
efSTReadRtInfoRequest*pReqBuffer,//
efSTReadRtInfoResponse   *   pResBuffer,//
unsigned long   Count   //
);
结构如下：
#define   EFMI_POINTNAMELENGTH 48
#define   EFMI_POINTCOMMLENGTH EFMI_POINTNAMELENGTH

//查询实时记录请求包结构

typedef   struct   defefSTReadRtInfoRequest{
long   time; //
char   pointName[EFMI_POINTNAMELENGTH+1];//EFMI_POINTNAMELENGTH+1;
char   ednaServ[EFMI_POINTCOMMLENGTH+1]; //  
}efSTReadRtInfoRequest;


//查询实时记录回复包结构

typedef   struct   defefSTReadRtResponse{

double   value;
long   time;
unsigned   short   status;//
char   pointName[EFMI_POINTNAMELENGTH+1];//
}efSTReadRtInfoResponse;
