Reading a File While Being Written to by Another Program(Windows)

Question

So basically, I'm trying to read a log file from a game while that game is running in order to have my program react to it in dynamic ways. I know it's possible , as other programs such as Notepad(++) are able to do it. However, after searching for an answer, most of what I can come up with is only Linux related.

I have no idea as to how to go about this, help in doing so with either C++ or C# would be great. Even though I would prefer native C++ over C#.

Answer 1

“原生”winapi解决方案是CreateFile ，特别是其dwShareMode参数。
