现在有一个DLL中的函数是：int ReadRecord1(int Address,Word RecNumber,Word *pEventNO, BYTE *pCardID,SYSTEMTIME &EventTime);我现在在Delphi中定义了这个函数：function ReadRecord1(Address: integer; RecNumber:Word;pEventNO
Word; pCardIDchar ;EventTime:SYSTEMTIME):integer;stdcall;external 'CVIOAccessAPI.dll';
但是在编译的时候会报错：[Error] UIOAccess.pas(134): Undeclared identifier: 'SYSTEMTIME'，请问这是怎么回事啊，该如何解决？SYSTEMTIME 的结构是这样的：
typedef struct _SYSTEMTIME {
WORD wYear;
WORD wMonth;
WORD wDayOfWeek;
WORD wDay;
WORD wHour;
WORD wMinute;
WORD wSecond;
WORD wMilliseconds;
} SYSTEMTIME;
Word; pCardIDchar ;EventTime:SYSTEMTIME):integer;stdcall;external 'CVIOAccessAPI.dll';但是在编译的时候会报错：[Error] UIOAccess.pas(134): Undeclared identifier: 'SYSTEMTIME'，请问这是怎么回事啊，该如何解决？SYSTEMTIME 的结构是这样的：
typedef struct _SYSTEMTIME {
WORD wYear;
WORD wMonth;
WORD wDayOfWeek;

} SYSTEMTIME;
