所以我似乎无法正确填写此构造函数的要求。
DIVA_STATUS DIVA_getObjectDetailsList (
IN BOOL pFirstTime,
IN time_t *initialTime,
IN int pListType,
IN int pObjectsListType,
IN int pMaxListSize,
IN DIVA_STRING pObjectName,
IN DIVA_STRING pObjectCategory
IN DIVA_STRING pMediaName
DIVA_LEVEL_OF_DETAIL pLevelOfDetail,
IN vector<DIVA_STRING> listPosition,
OUT vector<DIVA_OBJECT_DETAILS_LIST> *&pObjectDetailsList
)
问题似乎是输出类向量的最后一行(???)。我对C ++有点生疏,所以我不记得为什么你会取消引用参考调用(*&amp;)。
DIVA_OBJECT_DETAILS_LIST是一个如下所示的类:
class DIVA_OBJECT_DETAILS_LIST {
public:
int listType;
DIVA_STRING siteID;
vector<DIVA_STRING> *listPosition;
vector<DIVA_OBJECT_INFO> *objectInfo;
vector<DIVA_OBJECT_TAPE_INFO> *objectTapeInfo;
};
以下是我尝试使用VC ++ 2008 Express进行编译时得到的结果

以下是我调用构造函数的方法:
cr = DIVA_getObjectDetailsList (
_firstTime,
(time_t)_initDate,
(int)DIVA_OBJECTS_LIST,
(int)DIVA_OBJECTS_CREATED_SINCE,
_size,
_name,
_category,
_group,
DIVA_INSTANCE,
*_listType.listPosition,
&*_listType
);
_listType是DIVA_OBJECT_DETAILS_LIST。如何通过引用传递指针?
答案 0 :(得分:2)
问题似乎是倒数第二个参数。当您传递std::vector<DIVA_STRING>*
(而不是指针)时,您传递的是std::vector<DIVA_STRING>
。
但为了帮助您理解最后一个参数,vector<DIVA_OBJECT_DETAILS_LIST>*&
是“指向vector<DIVA_OBJECT_DETAILS_LIST>
”类型的指针。也就是说,你应该传递一个指针,然后通过引用传递它。
