在文件缓冲区上使用ifstream作为TCHAR * [英] Use ifstream on a filebuffer as TCHAR*

问题描述

我正在尝试使用Hans Dietrich关于如何将文本文件作为资源包含在exe文件XResFile中的精彩文章。我之前使用过ifstream的单独文件，



ifstream datfile（datf.txt）



我已经重载了>>运营商，我想继续使用。问题是该文章描述了返回TCHAR *的GetTextBuffer（）。如何将此指针转换为ifstream对象？



谢谢。



Haakon。

I am trying to use Hans Dietrich's great article on how to include a text file as a resource in a exe file, XResFile. I have previously used a separate file with ifstream,

ifstream datfile("datf.txt")

where I have overloaded the >> operator, which I would like to keep using. The problem is that the article describes the GetTextBuffer() which returns a TCHAR*. How can I convert this pointer to a ifstream object?

Thank you.

Haakon.

推荐答案

你不能。 ifstream 适用于文件和仅文件。如果你有一块内存，你想从中提取东西，那么使用 std :: strstream ，但需要注意的是它在C ++ '98和'03中被弃用了可能已在'11。

You can't. ifstream is for files and only files. If you have a block of memory that you want to extract stuff out of then use std::strstream, with the caveat that it was deprecated in C++'98 and '03 and might have been removed in '11.
