函数返回多个值的问题

[confach]

我写的函数如下：我想根据lpszBorough得到lpszCity和 lpszState
get_city_by_boro(LPSTR lpszBorough, LPSTR lpszCity, LPSTR lpszState)
{
BOOL mRtValue=FALSE;
if(lpszBorough== "M")
{
lpszCity = "Manhattan";
lpszState = "NY";
mRtValue = TRUE;
}
if(lpszBorough== "BK")
{
lpszCity = "Brooklyn";
lpszState = "NY";
mRtValue=TRUE;
}
if(lpszBorough== "QU")
{
lpszCity = "Queens";
lpszState = "NY";
mRtValue=TRUE;
}

return mRtValue;

}
测试：
LPSTR strCity;
LPSTR strState;
if(this->get_city_by_boro("M",strCity,strState))
{
MessageBox((CString)strCity+"\\"+(CString)strState);
}
但是结果为”\\",居然strCity和strState为空，这是为什么？

To BombZhang(我不入党) ，我试过，好象不行的。

get_city_by_boro(LPSTR lpszBorough, LPSTR &lpszCity, LPSTR &lpszState)

[beijingshizi]

弄个char aaa[256] ;
然后用 XXX( .. , &aaa , .... )试试

[闻缺陷则喜何志丹]

char strCity[1000];
char strState[1000];

get_city_by_boro(LPSTR lpszBorough, LPSTR lpszCity, LPSTR lpszState)
{
strcpy(plszCity,"s...");
}

错在 if(lpszBorough== "M")

改成 if(strcmp(lpszBorough,"M") == 0)

所以的If都要改。

用引用咯。

bool CReadExcelDlg::get_city_by_boro(LPSTR lpszBorough, LPSTR lpszCity, LPSTR lpszState)
{
BOOL mRtValue=FALSE;
if(strcmp(lpszBorough,"M")==0)
{
strcpy(lpszCity,"Manhattan");
strcpy(lpszState,"NY");
mRtValue = TRUE;
}
if(strcmp(lpszBorough,"BK")==0)
{
strcpy(lpszCity,"Brooklyn");
strcpy(lpszState,"NY");
mRtValue=TRUE;
}
if(strcmp(lpszBorough,"QU")==0)
{
strcpy(lpszCity,"Queens");
strcpy(lpszState,"NY");
mRtValue=TRUE;
}

return mRtValue;

}
