Question

c++的dll返回值为结构体,delphi如何调用?

类型说明：
typedef unsigned short INT16U;
typedef unsigned char INT8U;
typedef unsigned long INT32U;

typedefenum
{
TemHumNone,
TemHumLOAD,
TemHumSend,
}eType;

typedefstruct TemHumStatus

{
eType euType;
INT8U ucStatus;
INT8U ucNodeNum;
INT16U wTemp[8];
INT16U wHum[8];
INT8U ucYXStatus;
INT32U dwAddress;
}TemHumStatus;
以下为待调用的函数:
void CH_RoalPower_Init()
TemHumStatusCH_RoalPower_Unpack(INT8U *lpPtr, INT16U wUnPackSize);

INT16UCH_RoalPower_Pack(INT32U dwAddress, eType euMessgeType, INT8U* lpPre);

请高人指点,不甚感激!

你需要先申明与C++类型的内存结构一样的Delphi类型，然后再去调用函数。
