sh_none不是'std :: basic_filebuf< _Elem，_Traits>'的成员 [英] sh_none is not a member of 'std::basic_filebuf<_Elem,_Traits>'

问题描述

我尝试使用Microsoft特定的 filebuf： ：sh_none 变量以在独占模式（另一个Microsoft特定功能）中打开 fstream 。我得到了上面的错误。我正在导入< fstream> 。如何解决此错误？

I am trying to use the Microsoft Specific filebuf::sh_none variable to open an fstream in an exclusive mode (another Microsoft specific function). I am getting the above error. I am importing <fstream>. How can I fix this error?

UPDATE ：我发现此线程，其中建议我尝试_SH_DENYNO。代码编译，我现在测试它。这对我没有任何意义，因为这没有记录在函数中。

UPDATE: I found this thread, where it was suggested that I try _SH_DENYNO instead. The code compiles, I am testing it now. This doesn't make any sense to me, as this isn't documented in the function.

推荐答案

什么版本的Visual C ++

What version of Visual C++ are you using?

链接的Visual C ++ 6文档是iostreams的预标准版本，来自 #include< fstream.h> ; 。它不再可用，甚至在Visual C ++ 6.0中只有向后兼容性。

The Visual C++ 6 documentation you linked to is the pre-standard version of iostreams, from #include <fstream.h>. It's no longer available, and even in Visual C++ 6.0 was only there for backward compatibility.

此外， _SH_DENYNO 独占模式的相反。您希望 _SH_DENYRW 获得与 sh_none 相同的行为。以下是新文档： http://msdn.microsoft.com/en-us /library/44cs32f9.aspx ，最终导致您访问 http： //msdn.microsoft.com/en-us/library/8f30b0db.aspx 了解第三个参数的详细信息。

Also, _SH_DENYNO is the opposite of exclusive mode. You want _SH_DENYRW to get the same behavior as sh_none. Here is the new documentation: http://msdn.microsoft.com/en-us/library/44cs32f9.aspx, which ends up directing you to http://msdn.microsoft.com/en-us/library/8f30b0db.aspx for details on the third parameter.
