无法调用函数 [英] Cannot call a function

问题描述

你好，



我有这个代码：



EcosiaSearcher.h

Hello,

I have this code :

EcosiaSearcher.h

template <typename T, typename M>
	list<T> WINAPI do_search(string research, string parameters, void (M::*parse)(char* , list<T> &));

EcosiaSearcher.cpp

EcosiaSearcher.cpp

template <typename T, typename M>
list<T> WINAPI EcosiaSearcher::do_search(string research, string parameters, void (M::*parse)(char*, list<T> &))
{
	...
	list<T> results;

	...

	parse((char*)r_buffer, results);

	...

	return results;
}

template list<EcosiaWebResult> WINAPI EcosiaSearcher::do_search(string research, string parameters, void (EcosiaWebHtmlParser::*parse)(char*, list<EcosiaWebResult> &));

我尝试调用这样的函数：

And i try to call the function like this :

return EcosiaSearcher::do_search<EcosiaWebResult>(research, parameters, _web_parser.parse);

这是我想指出的功能的签名：

Here is the signature of the function i want to point :

void WINAPI parse(char* sz_buffer, list<EcosiaWebResult> &ls);

它不起作用。我有这个错误：

It doesn't work. I have this error :

Severity	Code	Description	Project	File	Line	Suppression State
Error	C3867	'EcosiaWebHtmlParser::parse': non-standard syntax; use '&' to create a pointer to member	Ecosiana	d:\users\deckbsd\source\projects\ecosiana\ecosiana\ecosiawebsearcher.cpp	17	

提前感谢您的时间和答案:)



我的尝试：



我也尝试过：



返回EcosiaSearcher :: do_search< ecosiawebresult>（研究，参数，和EcosiaWebHtmlParser ::解析）;



...

Thanks in advance for your time and answers :)

What I have tried:

I also tried :

return EcosiaSearcher::do_search<ecosiawebresult>(research, parameters, &EcosiaWebHtmlParser::parse);

...

推荐答案

这显然是编译器检测到的错误，它也会大声说出如何解决它。



在错误C3867 后用Google搜索解释了语法的一些细节。



因为你的全局范围我的函数会使用：

It is clearly an error which the compiler detect and it yells also how to fix it.

Googling after the Error C3867 and there is explained some details to the syntax.

Because your function with global scopeI would use:

do_search(research, parameters, &parse);

全部谢谢你的回复:)



确切地说C ++不是C＃我做得对：

Thanks all for your replies :)

Exactly C++ is not C# i did it correctly :

template <typename typename="" m="">
list<t> WINAPI EcosiaSearcher::do_search(string research, string parameters, string page, M& parser, void (M::*parse)(char*, list<t> &))

</t></t></typename>

(parser.*parse)((char*)r_buffer, results);

template list<ecosiavideoresult> WINAPI EcosiaSearcher::do_search(string research, string parameters, string page, EcosiaVideoHtmlParser &parser, void (EcosiaVideoHtmlParser::*parse)(char*, list<ecosiavideoresult> &));
</ecosiavideoresult></ecosiavideoresult>

和电话：

and the call :

return EcosiaSearcher::do_search<ecosiawebresult>(research, parameters, ECOSIA_SEARCH_PAGE, _web_parser, &EcosiaWebHtmlParser::parse);
</ecosiawebresult>

最好的问候，
